Use this in the blog opening: Production setbacks are the primary reason 97% of consumer hardware startups fail to deliver their products on time, with many shutting down completely. The transition from a working prototype to high-volume manufacturing is often described as the "manufacturing valley of death".

------------------

Here are 5 common production setbacks that kill hardware startups, along with strategies to prevent them.
1. Ignoring Design for Manufacturability (DFM) Early
Startups often create functional prototypes using methods (like 3D printing or CNC machining) that cannot be scaled. When moving to injection molding or mass production, the design proves "unbuildable," causing massive redesign delays and cost overruns.

How to Prevent It:
Involve a Contract Manufacturer (CM) early: Bring manufacturing experts into the design loop during the prototyping phase to review for DFM.
Simplify the design: Use standard, off-the-shelf components instead of highly customized parts that are difficult to produce in volume.
Test for mass production: Ensure the design includes draft angles, proper wall thicknesses, and, and that it is designed to be assembled quickly at scale.

2. Underestimating Time and Cost of Production
Founders often assume hardware can be "lean" and brought to market in 2–3 months, failing to budget for tooling, certification (CE, FCC), testing, and shipping. Unexpected costs often balloon to 30–70% over budget.

How to Prevent It:
Build in financial buffers: Add a 15–20% contingency budget and 30–70% extra time for unforeseen setbacks.
Validate BOM costs: Verify the Bill of Materials (BOM) with a CM early to ensure it is not just a wishlist, but a realistic cost sheet.
Budget for tooling: Account for expensive, long-lead-time molds and tooling required for mass production.

How to Prevent It:
Find a "Bridge" Manufacturer: Look for CMs that specialize in low-to-mid volume (500–10k units) that can handle the transition from prototype to full production.
Vet for communication and quality: Ensure the manufacturer can discuss engineering and technical details directly, not just through a middleman.
Build a strong relationship: Conduct on-site visits and establish clear quality standards early.

How to Prevent It:
Diversify suppliers: Never rely on a single-source supplier for key components.
Regularly review component availability: Keep track of the lifecycle of parts and have a substitution plan for obsolete components.
Buffer critical stock: Keep key parts in reserve to prevent disruptions.

How to Prevent It:
Run pilot production: Produce a small, "pre-production" batch (100–500 units) to test the entire manufacturing process and uncover defects.
Use automated testing: Develop test jigs and flashing stations to ensure consistent quality in every unit.
Conduct environmental tests: Test for harsh conditions, such as extreme temperatures, high altitude, and humidity

Why Hardware Startups Fail — and How Engineering Strategy Can Save Them
Introduction: Hardware Is Hard — But Failure Is Not Inevitable
Software startups can iterate fast. Hardware startups? Not so much. Long development cycles, high upfront costs, and manufacturing complexity make building hardware especially risky — especially for first-time founders.

Yet, many failures come not from bad ideas, but from weak execution in engineering and product development. In this article, we examine why hardware startups fail and how a robust engineering strategy can drastically improve the odds of success.



1. Underestimating Time and Cost of Hardware Development
Unlike software MVPs, hardware requires:

Custom PCB design and prototyping
Regulatory testing and certification
Tooling for mechanical enclosures
Manufacturing and supply chain coordination
Common mistakes:

Assuming hardware can be done “lean” in 2–3 months
Underbudgeting for iterations or test failures
Ignoring per-unit cost structure and BOM targets
How to fix:

Build a realistic timeline with prototyping, pre-certification, and pilot production phases
Validate BOM costs early with your EMS or DFM consultant
Use off-the-shelf SoMs or evaluation kits for MVPs


2. No DFM/DFA Strategy from the Start
Many startups focus only on functionality in the early phase — but forget to make the product manufacturable.

Signs of trouble:

PCBs not optimized for yield or test coverage
Enclosures difficult to assemble or scale
Over-customized components not available in volume
What to do:

Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles early
Involve a contract manufacturer (CM) or EMS partner in the design loop
Use standard connectors, package sizes, and mounting strategies


3. Ignoring Compliance and Certification
Many hardware startups forget that CE, FCC, or RoHS aren’t just checkboxes — they’re gates to enter global markets.

Common missteps:

Skipping pre-compliance testing
Using non-compliant components or wireless modules
Delaying regulatory planning until too late
Engineering strategy tip:

Plan certification from day one: identify all needed standards
Choose pre-certified modules or platforms (e.g. Bluetooth, Wi-Fi)
Reserve time and budget for lab testing and paperwork


4. Fragmented Firmware and Hardware Co-Development
Hardware and firmware teams working in silos often lead to misaligned interfaces, integration bugs, and delayed validation.

Avoid this by:

Establishing hardware–software co-design from the beginning
Sharing interface specifications and version control across teams
Using emulators and simulators to test firmware before hardware is ready
Promwad frequently bridges firmware and hardware integration for clients launching their first product — reducing bugs and test delays by 30–40%.



5. Failing to Plan for Production and Scaling
Shipping 10 prototypes isn’t the same as building 10,000 units. Many startups get stuck after proof-of-concept due to a lack of:

Test automation
Supply chain coordination
Yield monitoring and post-sale support
Build with scale in mind:

Add test points and debug headers to every board
Develop scalable test jigs and flashing stations
Use an ERP or tracking system early for logistics


 Top Startup Failures and How Strategy Prevents Them




Summary Table: Top Startup Failures and How Strategy Prevents Them
Pitfall	Resulting Risk	Strategy to Prevent It
Underestimating time/cost	Missed launch, budget overrun	Phase planning, validated BOM
No DFM/DFA	Unbuildable design, high unit cost	Early EMS engagement, standard components
Skipping compliance	Market access blocked, legal risks	Pre-cert labs, certified wireless modules
Siloed HW/SW teams	Firmware bugs, integration delays	Co-design, shared specs, test simulators
No production scale plan	Post-MVP failure, QA issues	Test jigs, flashing automation, ERP setup


6. Lack of Risk Management and Contingency Planning
Hardware development is full of uncertainty — from component shortages to factory defects. Startups often fail to anticipate risk at each stage of development.

Typical oversights:

Assuming EMS partners will handle every quality issue
Relying on a single supplier for key components
No contingency budget for redesigns or compliance rework
Engineering strategy tip:

Conduct risk mapping (supply chain, design, certification, scaling)
Build 10–15% contingency into cost and timeline projections
Develop a component substitution plan and lifecycle monitoring


7. Poor User Feedback Integration
Startups that skip field testing or ignore early user feedback often miss critical flaws that derail the product post-launch.

Examples of missed insight:

Enclosure heat issues not identified in lab tests
User confusion due to unvalidated UI/UX
Field failures due to assumptions about install conditions
Preventative strategies:

Run structured field trials or beta deployments
Use telemetry to monitor behavior in real conditions
Build feedback loops into product update planning


Final Thoughts: Engineering Strategy Is a Startup’s Survival Tool
Most hardware startup failures are avoidable — if product development is grounded in solid engineering practice.

Promwad supports early-stage companies with:

Architecture planning and design reviews
Custom hardware/firmware development
DFM and EMS onboarding
Certification consulting and lifecycle support

Why 90% of Hardware Startups Fail?
During the years we served thousands of creators / innovators coming to us with fantastic designs, which reflect their ideas for changing something. For each one, we, as a manufacturing partner, are always proactive and eager to help and do something in their journey. That’s not only motivated by business opportunities, but also out of a sense of inherent responsibility.

Therefore, I watched, experienced, and attended many cases and saw their up-and-down, from a close distance and a special view angle, as an observer and participant. For those being successfully launched and growing up, we can feel and enjoy the tangible positive results. While for those less fortunate, their voices faded gradually silently until they could no longer be heard, leaving a mess of unfinished redesigns, untested 8th-loop prototypes, unreplied supplier emails, ignored customer calls, and the bank account reduced to zero…

I wrote this piece not to educate, but to inspire thought: what are factors leading to success and failure, what should be avoided in hardware creation journey.

The purpose of this work is to provide guidance that might be helpful at the time you’re planning your own creative journey.

Understand the Truth:

There’s statistics that hardware creation success rate is not higher than 10%, failure no less than 90% CB Insights Report and MacroFab analysis.

Cruel, isn’t it?

For what reasons do those fall?

funding?
competition?
manufacturing?
technical hurdles?
After long years of watching and real experiences, I realize the answer is not so simple and superficial. It’s rooted in a dark and hidden area, which can only be discovered by careful observation over time.

From the eyes of someone in manufacturing industry, this is not to analyze or reason logically, but patterns or reality concluded from different specific cases and common traits found among them.

1) Unrealistic judgement of time frame

You set up the whole project and break them down to segments, each one with a specific number of days to go:

electronics, hardware, mechanical designs: 14days prototype: 21days test and validation: 7days design modification: 14days 2nd prototype loop: 21days retest and revalidation: 7days

When it’s in process, you’ll find a small slow-down or deviation will break the schedule. You have to rewrite the timeline on your project management board again and again.

When you experience this more than three time, you’d get used to such change.

What’s wrong with your timetable?

Nothing.

This is how things really go in the real world.

The timetable is a reflection of your idealism and perfectionism.

It’s time for you to see the reality.

Date for reference:

most creators underestimate overall timeline by 2x or 4x
underestimate certification timeline by 3x
underestimate manufacturing difficulty by 10x
In reality, when timeline is broken, two results come along the way:

cash burning accelerating
investor confidence and passion dropping
It worsens when the two intersect. That’ll push the project closer to failure.

Truth is creators need 3 cycles to learn and be good at setting up timelines with a realistic mindset.

2) Revision — another killer for budget drain

You surely won’t foresee so many changes / revisions after you start prototyping, along the way through to engineering sampling, pilot run sampling, and production sampling. These engineering changes will bring anything you won’t predict or imagine during planning stage.

These revisions will consume your patience, enthusiasm, perseverance… They will weaken your team morale, They will quickly drain your budget in a visible manner.

Revision is such a ghost waiting on the road of your journey, smiling and waving, friendly and malicious.

Many don’t realize they will endure 3–8 prototype loops, Each loop increased prototype cost 15–40%, Mechanical parts cost increased by 40% or more, Electronics cost increases by another 30%

Take an example: from you need to change a connector → PCB changes → enclosure changes → tooling changes → schedule collapses → more cost.

If you have to add a new sensor → new firmware → power redesign → new EMC failure → more redesign.

What you’ve seen in the revision chain is increased cost.

You may feel uneasy considering those increased costs. A compromising thinking mode breeds in your brain.

looking for lower pricing parts.
skipping reliability testing
skipping some certification
removing some features to reduce cost
change supplier temporarily for lower pricing
force current supplier to find a cheaper solution
You might ignore an inner warning voice and let things move on.

3) Temporary supply chain network building

There is no correct or incorrect time for when to build a supply chain network. But the best way is the earlier, the better.

You need a long time of communication with supplier to identify if they’re the right one for you.

It’s not just about pricing, which is merely an aspect of supplier evaluation.

Is communication smooth?
Can you both sides easily understand each other?
Will one side consider something unspoken by the other side in making decision?
Except business negotiation, can the other discuss directly technical and engineering points with you with no other people’s help?
Is the response timely or after a long time?
Someone who always can not catch up with you will eventually frustrate you. On the other hand, a good communicator will bring ease and good feeling while mutual understanding is reached.

What will you consider when selecting someone to be your supplier besides communication?

more convenient?
lower pricing?
relative or friend’s introduction?
local source?
You find someone to make your prototype and pilot run, small batch 100pcs, 200pcs, all seems OK.

But once you require 500pcs, 1000pcs, 5000pcs, they fail.

You may wonder what’s wrong when it scales?

McKinsey’s 2023 survey(McKinsey Report on Hardware Startups):

67% of hardware startups fail during scaling
52% of delays come from supplier-side issues
teams underestimate lead time by 30–70%
Startup creators build the supply chain this way:

Design first
Prototype
Find supplier
Adjust design
Run into problems
Change supplier
Redesign again
They will hand some most important job to someone with no long-time communication and verification for their processing capabilities, quality, manufacturing, engineering, packaging and packing, shipping and logistics.

In other words, they give the work to someone they actually don’t understand, while they understand technical and materials so well.

Those succeeding will do it another way:

involve suppliers early
design with manufacturability in mind
let manufacturing experts highlight risks
simplify the BOM early
commit to stable partners
Good supplier dose not come right when you need. It’s something that you’ve spent a long time to build a network intentionally and strategically.

4) Building a product without building a business

This is so commonly found.

Project teams put their most energy and time on building the tangible product, while neglecting the product serving another purpose: a business.

The business that includes not only the product, the people in the office, supply chains, channels and distributors, marketing partners, sales platforms, KOLs(Key of Leaders), customers, and other associates who are involved in the projects.

Product is not business, business needs product.

While we can often see teams spend:

90% on engineering
10% on marketing
0% on pricing
0% on distribution
0% on long-term cost structure
When the product is ready for market, they find:

customer acquisition cost soaring
return cost so high
marketing fees exceeding expectation
Ads cost running at an unacceptable level
logistics fees greatly shrinking margin
every corner around product cutting profits
A dataset from Hardware Club shows:

58% ran out of cash because of wrong pricing
37% never reached market due to no distribution plan
26% built something the market didn’t want Hardware Club Report
Your engineering expertise brings the product to the world.

Business decides whether it can exist in the world.

5) Creator’s overoptimism, overconfidence, vision drift

It’s popular to hear from creators:

hardware founders are 2.4x more optimistic than software.
70% founders believe their product will be shipped in 12 months.
68% change product direction at least 3 times.
Every time direction changes will cause a new setup for everything:

design
engineering validation
prototype and test
supplier reverification
BOM
cost update
timeline update
Vision drift is a real threat to any product realization.

6) Wrong manufacturing partner

There’s no absolute best, there’s only a relatively best fitting.

Different companies at their specific development stage find the best partners who can meet their specific standards.

For startups, the best ones are those who can provide constructive suggestions on processing ways, materials, optimized engineering solutions, suitable tolerances, adaptive cost structure…, they can provide suggestions beyond just saying Yes, and they actually:

push back on impossible tolerances
warn you about exploding costs
recommend alternative materials
fix DFM issues early
highlight high-risk features
forecast bottlenecks
tell you what will break
Is it like your internal engineer? Yes, that’s what a good manufacture partner can do.

What they do is not just a supplier, they act like an advisor.

That’s the value a good manufacture partner can bring.

Stats show:

70% of successful projects had early supplier involvement
only 17% of failed projects had any early involvement
52% ignored manufacturability early
Your product is a demonstration of that it is only as strong as the weakest supplier in your chain.

How to avoid these failures?

We don’t talk about theories, but methods adopted by flying teams which get them through the difficult journey.

Define timeline in cycles, not dates.
By cycle, you emphasize completion of the task, this is result-oriented, and outcome performance. This is just what plays critically in successful founder’s mindset on how they judge, think, and decide.

Instead, everyone will feel the weight of pressure from a deadline date. They’re afraid of being lagged, they worry about low performance, so choices are not optimal, actions are hasty, logical thinking chains are short, decisions are made out of short-term consideration…

Think in cycles:

prototype cycle
mechanical cycle
electronics cycle
certification cycle
e.g., instead of prototyping taking 3 weeks, assume 2 cycles.

2. Build financial buffers

Successful projects plan budgets this way:

development × 2
certification × 1.5
supply chain setup × 1.5
manufacturing ramp × 2
With such budgets, you’ll feel at ease when confronting surprises.

3. Building supply network in early years, not when designs are finished.

Talk to them even at concept stage, or years before you think you’ll be a founder in the future. Ask for warnings/suggestions, not just quotes.

Advice, don’t delete a manufacturer’s cold email directly, but read it and interact with those good ones.

4. Validate an MSM (Minimum Success Model) before scaling.

With current business operation, ask the difficult questions early:

Do we truly make margin?
Can we afford distribution?
What is the return handling cost?
What is the cost of customer acquisition?
If the business model fails, engineering cannot rescue it.

5. Fix core product vision

Whatever a feature seems attractive as it may be, freeze such idea.

“NO MORE FEATURES” should be a rule. Stop thinking of adding any new features to increase product attraction.

Vision drift within a cycle is harmful.

What to do with the vision?

Only for feedback from early stage test users.

6. Align engineering and procurement on the same page

One BOM. One version. One communication channel. They update with each other every check meeting. They synchronize immediately when a difference is found.

7. Remember: execution over idea

Ideas are cheap, free, no efforts to exert.

Execution is expensive, energy consuming, result-producing.

Execution is where most teams fall.

Conclusions: Respect the Reality

After attending and watching so many projects — from successes to failures, I truly believe success doesn’t reward the most creative, best-looking, most intelligent.

It rewards those who’re disciplined.

They’re disciplined at:

timeline
costing
testing
communication
supply chain choices
decisions
Every team has its shortcut, every shortcut will be paid for.

But you can still go to the finish line by avoiding as less as possible those failures or project killers.

As a manufacturing partner, your success shapes ours as well.

When your project is growing to be great, we grow with you.

And we hope to be the partner who stands beside you — from the first idea sketch, through the hard middle, all the way to a finished product in someone’s hands.

That’s only wish we have.

14 Common Mistakes Hardware Startups Should Avoid
Everyone loves a success story, but failures tend to be shoved under the carpet. However, we can learn much more from failure than from success. In this way, failure is a stepping stone to success. In the hardware startup world, there have been many failures, and we can learn from the mistakes these startups have made that ultimately led to their demise.

Here are some of the most common mistakes that hardware startups make and advice on how to avoid them:

Not building a prototype that works in different conditions
This is the first step in your hardware startup journey and can greatly impact your progress. Let’s say you’ve built a great prototype that works well near sea level. What happens when the same product is taken to a higher altitude?

Questions such as these need to be answered before you start shipping out faulty products to customers. If you’re building a hardware product in an industry such as healthcare, automotive, or aerospace, testing the product for various different scenarios becomes even more critical.

It’s imperative for hardware startups to test their product for different scenarios and environments. This will ensure that you don’t end up shipping defective units to your customers. After all, your credibility and your customer’s trust are at stake.

You may think it’s practically impossible to test a product for multiple different scenarios. If you’re thinking of physical prototypes, yes it is. But there is another way you can test your product in a low-cost, low-risk environment: engineering simulation. Engineering simulation software helps you test your ideas virtually in any number of real-world scenarios. Startups can look at programs such as the ANSYS Startup Program that offer simulation solutions to startups.

Failing to take manufacturability into account
So, you’ve created a fully functional prototype. Congratulations! But wait, now you now have to face the hurdle that most hardware startups have trouble with once their prototype is ready: manufacturing their product at scale. This is also known as “Design for Manufacturability”.

You could’ve used prototyping boards such as Raspberry Pi or Arduino for building your prototype, but bear in mind that these are not viable options to manufacture your product at scale. Another challenge that hardware startups face is designing their product enclosure.

While enclosures for prototypes can be built using 3D printing, production units use injection molding to build at scale. It’s important to take into consideration all the modifications your enclosure will go through when using this method since it has several design rules that you must follow.

Skipping market research
Let’s face it: every founder is in love with their idea. But do you know what the success of your hardware product depends on? The answer is how much your target audience loves your idea (and the product you finally build).

Try as you might avoid the marketing side of starting a business, this is where you should begin research for your hardware startup.

Begin by asking yourself ‘who am I building this product for?’ This is your target audience. Next, think of what problem your product is solving for these people. Is this a real problem your audience is facing or something you’ve cooked up to sell a product? If you are creating a simple B2C product, the best way to find out is to speak to your target audience face-to-face or online (community forums, social media). In some cases, if you are creating a groundbreaking technology, you will also have to identify the few experts in your field who might be able to help out with valuable insights.

Another aspect of market research is finding out who your competitors are and how you will differentiate your product from theirs. If your research is solid, you’ll know which core features of your product matter most to customers. If not, you’ll end up with a product that nobody needs, packed with too many features that nobody uses.

Underestimating development costs
It’s important to take into account how much you’ll be spending on development in order to have a healthy profit margin.

We are not referring to prototyping costs. Thanks to modern software simulation tools, prototyping can be made substantially cheaper in comparison to building a costly physical prototype by trial and error. But the cost of manufacturing your product at scale is what you really need to consider: assembly, warehousing, certifications, packaging, and shipping. And let’s not forget delays and defects that you may have to deal with.

It’s crucial to take these into account while setting your sales price or you’ll end up with no profit margin, as well as delays in product manufacturing.

Developing “too many” features
This is not necessarily exclusive to hardware startups, but many of them are guilty of committing this mistake.

Developing too many features can be very expensive and time-consuming, and at launch, you may end up with a generic product that nobody really wants. Instead, focus your energy on developing one single feature that your target audience needs and doing it better than anyone else in the market.

Remember that a product that performs one function in a superior way is better than a product that performs 10 functions in an average way. The more features you try to add, the more chances of things going wrong, wasting your time and resources.

Hardware startups should first develop an MVP with one core feature. Take that to potential customers, get their feedback, and then work on developing a better version. Don’t try to develop your final product on the first attempt.

Choosing the wrong manufacturing partner
Your manufacturer carries the success of your product on his shoulders. Why? Because no matter how good your prototype is, it only matters how well you can develop the product at scale.

It is vital to choose a manufacturing partner that is both competent and can meet deadlines. Before you zero in your manufacturer, be sure to speak to as many candidates as possible, and put proper documentation in place, to avoid delays and roadblocks.

Spend as much time as possible with your manufacturing partner to build a strong relationship. Set expectations in the beginning, from a quality of production to production schedules. It’s also important to choose the optimal factory size. If the factory manufactures millions of parts every month, they may not be willing to give the necessary attention to your order.

Lack of a differentiating factor
Why do people buy iPhones when other cheaper phones are available on the market? Some of these phones have even managed to copy the features that Apple offers, such as interface and style. Why is iPhone still the leader in the market?

Because consumers know that Apple is an innovator. While every product can be copied, you need to have the ability to innovate and lead the market by being the first to offer unique ways to solve problems that set you aside from the pack. Patents can be an expensive, especially if you don’t have institutional investment.

In order to differentiate your product, you need to build a strong brand, offer great customer support, and build a community around your company.

Keeping insufficient profit margins
Your profit margin depends on two things: the cost of manufacturing your product and the sale price of your product. If you underestimate your cost of production or overestimate the price people are willing to pay for your product, you’ll end up with a low-profit-margin.

In the beginning, it’s common to see a low-profit-margin, as you don’t have the benefit of economies of scale. Once you start manufacturing large batches, you need to find a way to lower your cost of production so your profit margin can go higher.

Profit margins are essential to keeping your company afloat. Lower profit margins will also mean fewer resources to invest back into your business.

At launch, a low-profit-margin may be acceptable. But you have to eventually make a profit to be able to sustain your company, yourself, and your family. Even in the beginning, having low-profit margins will make growing your startup much more challenging because you won’t have any significant profit to invest back into your company.

Not working out cash flow needs
Many startups struggle with this, and it happens to be the second most important glitch after manufacturing.

First of all, there is the cost of developing a prototype. Depending on the complexity of your product, this can be an expensive affair. Luckily, hardware startups have the option of developing multiple virtual prototypes to see if their idea is feasible in the real-world through engineering simulation. Programs such as the ANSYS Startup Program offer multiple simulation options to startups.

After prototyping, startups need steady cash flow for manufacturing. Manufacturers generally require 50% upfront payment for production.

On the other hand, when you sell your inventory, it is likely that your clients will pay you after 30 to 90 days. So, you’re looking at financing a good part of the inventory yourself, until you get paid.

In the early days, it is often essential to have an initial investment, ensuring your cash flow needs are met on time.

Failing to invest in marketing
Hardware startup founders are often solely focused on building the product, and ignoring marketing altogether. “Build it and they will come” is surely a recipe for failure.

If marketing is not your strong suit, then it helps to have a co-founder with valuable marketing experience. You can also hire an independent sales representative so they can set up distribution channels and start acquiring customers. Most of the time, sales representatives get paid on a commission basis, so you only pay once the sale has been made.

It’s important to figure out a sales strategy early on. Don’t just focus on hiring engineering talent. Also, look at adding valuable marketing and sales hires to your team, and identifying who can focus on customer acquisition.

Focusing on ‘beauty’ over ‘value’
While there’s nothing wrong with beautiful products, they should also work properly.

While the design is one of the plus points of the iPhone, let’s not forget that the product is superior too. Many startups try to simply design a beautiful product and don’t invest too much in core functionality. The thing is customers don’t care as much about how your product looks, as much as they care about how well it works. So it doesn’t make sense spending precious dollars on an aesthetic designer.

In the beginning, it’s okay to ship not-so-good-looking products to early adopters, so you can get feedback from them. The design is something you can always work on later.

Choosing the wrong cofounder
This is where a lot of startups falter in general, not just hardware startups. A co-founder should ideally bring complementary skill sets to the table, and essentially complete you.

This means if you’re a technical founder, you need someone with business acumen and marketing know-how. On the other hand, if you’re a salesperson, and have zero knowledge about building hardware, you obviously need someone to bring your ideas to life. Avoid choosing someone with the exact same skill set.

Another important factor among co-founders is the presence of trust and mutual understanding. If you don’t believe in each other’s vision and skills, you’re probably not a good fit for each other.

Mismanagement of inventory
It’s important to have a handle on inventory if you don’t want things to spin out of control. If you manufacture too many units, you will have to wait until all of them are sold. On the other hand, if there’s a lot of demand and no product, you’ll lose customers.

Also, keep in mind that it costs money to store and ensure inventory. To avoid losses and lost opportunities, have a dedicated inventory management system in place for your startup.

Going to investors too soon, or too late
As a B2B hardware startup, you’re likely to need a good amount of initial investment to start manufacturing your product. If you need money from investors, by all means, go to them. Do not wait until your idea can no longer be salvaged, or has already been copied.

On the other hand, if you think you can sustain your company without outside investment, hold off on seeking investors. Spend some time doing research on which investors would be interested in your product, and have experience in your industry. Once you’ve done some research, approach them cautiously.

Conclusion

We hope you can learn a thing or two from the most common mistakes that hardware startups make. Are you guilty of making any of these mistakes? How did you rectify them and save your startup?

Top 7 DFM Mistakes Hardware Startups Make and How to Avoid Them

Introduction
Design for Manufacturing (DFM) is a critical stage in hardware product development, yet many startups overlook essential details in the rush to launch. This oversight often results in common DFM mistakes that delay production, increase costs, or compromise quality. For early-stage companies, avoiding these mistakes can mean the difference between a smooth market entry and a costly redesign. Startups often face challenges balancing innovation with practicality. While ambitious designs may excite investors and potential customers, overlooking manufacturability can lead to tooling errors, material issues, and long lead times. Many of these challenges can be mitigated with structured DFM planning and expert guidance from hardware product development specialists. In this article, we examine the top seven mistakes startups make in DFM, with practical solutions for each.

1. Ignoring Manufacturability in Early Design
The most common mistake startups make is pushing a design forward without considering manufacturability. While a design may look great in CAD software, it may be difficult or costly to reproduce at scale. How to Avoid:

Engage manufacturing engineers during the early design phase.
Conduct feasibility reviews before finalising design files.
Use prototyping to validate manufacturability.
2. Overlooking Material Selection
Material choice affects not only cost but also durability, weight, and production speed. Poor material selection can lead to failures in stress tests or unexpected cost overruns. How to Avoid:

Compare materials for mechanical strength, environmental resistance, and availability.
Evaluate sustainability and recyclability where relevant.
Consider both short-term prototyping needs and long-term mass production requirements.
Practical insights and case studies on design for manufacturing best practices can help startups refine material choices. Detailed service support is available through specialist DFM design services.

3. Neglecting Tolerances and Fit
Startups often underestimate the importance of tolerances when specifying parts. Overly tight tolerances increase machining costs, while loose tolerances can result in poor fits and product failure. How to Avoid:

Apply geometric dimensioning and tolerancing (GD&T).
Focus on critical tolerances instead of over-specifying all dimensions.
Validate tolerances during prototyping stages.
4. Miscommunication with Suppliers
Poor communication with suppliers can cause significant production setbacks. Without clear specifications and feedback loops, tooling errors and manufacturing delays become more likely. How to Avoid:

Establish open and consistent communication channels.
Share detailed technical drawings, not just CAD models.
Request design-for-manufacture input from suppliers before final approval.
5. Underestimating Tooling Errors
Tooling is one of the most expensive parts of production. Startups frequently run into problems by assuming a tool will work perfectly on the first run. Tooling errors can result in wasted time, increased costs, and missed deadlines. How to Avoid:

Conduct a tooling validation process with trial runs.
Use rapid tooling for low-volume production before committing to high-cost tooling.
Work with experienced toolmakers who understand startup constraints.
6. Failing to Account for Cost Overruns
Startups are often surprised by hidden costs such as shipping, retooling, and late-stage material substitutions. These cost overruns can quickly strain limited budgets. How to Avoid:

Include a cost buffer of at least 15–20% in manufacturing budgets.
Monitor cost drivers like material pricing and supplier lead times.
Balance quality with budget by considering design alternatives.
The following table illustrates how early-stage planning can reduce cost-related issues:

Stage	Common Oversight	Impact	Solution
Concept Design	Ignoring manufacturability	Redesign costs	Early DFM review
Prototype Phase	Wrong material choice	Weak or failing parts	Material comparison and testing
Tooling Preparation	Skipping trial runs	Expensive retooling	Rapid tooling validation
Production Scaling	Supplier miscommunication	Delays and cost overruns	Clear specs and open feedback loops
7. Overlooking Long-Term Scalability
Startups often design for short-term needs without considering how a product will scale to thousands of units. Components that are easy to produce in low volumes may not be suitable for mass manufacturing. How to Avoid:

Validate assembly processes for high-volume runs.
Choose scalable materials and suppliers from the beginning.
Plan for future cost reductions through design simplification.
Scaling requires not just technical preparation but also skilled teams. Many organisations expand their capabilities by hiring engineers experienced in manufacturability. Opportunities in careers focused on product development and DFM highlight the growing demand for professionals in this field.

8. Overlooking Electronic Component Selection
In hardware product development, electronic components are the backbone of functionality. Startups often neglect to thoroughly evaluate component availability, lifecycle, and support, which can cause critical setbacks. Choosing parts that are nearing end of life or have limited supply can result in redesigns and costly delays soon after launch. How to Avoid:

Verify component availability and supplier lead times.
Check alternatives to ensure flexibility in case of shortages.
Confirm that selected parts are not scheduled for end-of-life (EOL).
Ensure adequate technical support is available from the chip or component supplier, especially for complex designs.
By addressing component selection early, startups can protect their designs from sudden disruptions and avoid being forced into time-consuming redesigns.

Five Common Pitfalls of Hardware Product Development (and How You Can Avoid Them)

As the old saying goes, “Hardware is hard!”.

Yes, it’s true – hardware product development can be challenging and complex, requiring significant time, resources, and capital investment. Unlike software startups, hardware startups face unique challenges such as manufacturing, supply chain management, and hardware design. As a result, the failure rate for hardware startups is higher than that of software startups.

According to a study conducted by CB Insights, 97% of hardware startups fail to deliver their product on time, and 70% fail to deliver their product at all.

These trends remain remarkably consistent year after year, even as technology advancements progress.

So why exactly do so many hardware startups fail?

While learning from your mistakes is often necessary in the product development process, it is much more efficient to learn from the mistakes of others. Over the years, Product Creation Studio has worked with many hardware products from startups to established brands. This article details some common pitfalls that hardware teams may face when working on a new product initiative.

Pitfall #1: Underestimating the complexity and cost of the product development process.
Hardware product development involves multiple stages, including research, design, prototyping, testing, and manufacturing. Each stage requires significant resources and expertise, which may need to be clarified for those new to the innovation and product development process.

In early-stage startups, each team member often wears multiple hats. Therefore, these groups often need more hardware design and engineering expertise to navigate their product all the way through manufacturing and to market.

These business owners and entrepreneurs are often optimistic about their product’s potential for success. To bring it to market quickly and efficiently, they may try to simplify or reduce specific steps in the development process.

Unfortunately, this can result from a lack of consideration for product development's inherent risks and challenges. Additionally, external pressures such as investor expectations or deadlines can cause companies to underestimate the development process's complexity, timeline, and cost.

When managed properly, the product development process enables companies to allocate resources effectively, plan realistic development timelines, manage risks appropriately, make informed investment decisions, and communicate progress effectively.

Companies may underestimate the time and resources required without accurate estimates, leading to delays or project failure. Furthermore, identifying potential risks and challenges early on allows companies to plan and implement appropriate risk mitigation strategies, reducing the likelihood of project failure.

To pass forward the wisdom I learned from a trusted mentor early in my product-making career – “slow down to succeed quickly.”

Pitfall #2: Neglecting supply chain considerations.
Startup products often originate as an idea in the minds of entrepreneurs and then race as quickly as possible headlong toward production.

Founders hire engineers to turn their idea into reality, and those engineers develop the best product possible with the resources they have.

The complex nature of the supply chain, especially in recent years, involving multiple suppliers, manufacturers, and distributors, makes it challenging to manage, which increases the likelihood of errors or delays. Disruptions in the supply chain can also significantly impact the product development process, including milestone delays, cost overruns, and even product failure.

As such, managing the supply chain effectively is critical to the success of your product.

A well-designed supply chain strategy can ultimately help manage costs by optimizing procurement processes, mitigating component continuity of supply issues, negotiating beneficial component pricing, and identifying opportunities for cost savings over time–all of which are critical success criteria for a startup.

Furthermore, a solid supply chain strategy highlights when and where to make crucial decisions, which can improve product quality. Sometimes supply chain awareness even leads to a significant pivot in strategy. This can ultimately result in smoother, high-quality component substitutions when required.

Collaborating with a company that has built authentic relationships with various component providers over several years of successful product development can help you avoid potential setbacks and pitfalls in this stage of the product development process.

Pitfall #3: Problems scaling production.
Scaling production requires coordinating and aligning multiple suppliers, manufacturers, and distributors, which can add to the complexity and increase the likelihood of costly errors.

In reality, it is not uncommon for startups to have key materials or components that just don’t show up in time to support manufacturing needs. Alternatively, we also see cases where inventory piles up before production lines are even greenlit, leading to logistics problems for the manufacturing partner.

When supplier relationships, inventory control, manufacturing capacity, factory validation, and process optimization, are not given the necessary attention, misalignments and costly errors can arise as production volumes ramp up to meet targets.

In order to scale production successfully, these situations must be avoided at all costs.

Exacerbating this is a tendency at some startups to lavish resources on key product features, and in turn to skimp on production readiness. While features may impress investors and even increase revenue estimates, don’t overlook the importance of scaling and validating through production. Hardware business models depend on reliable products, delivered to all customers.

Both are important to achieving success, and balance is required.

Scaling production ensures that a mature, quality product is produced. You can meet the increasing demand for your product throughout the production lifecycle, which is essential for long-term success and profitability.

Pitfall #4: Failure to adequately test and validate the product before production.
Failure to adequately test, among many things, can lead to product immaturity and defects, resulting in recalls, customer dissatisfaction, and ultimately reputational damage.

Engineering Testing and Validation are essential to hardware product development, validating and refining the design before production. Engineering testing of initial prototypes ensures that the product design functions as intended at both the subsystem and system levels.  Design modifications may be required, but making those improvements before moving into production is essential to avoid costly redesign work.

Companies often fail to test and validate their products due to inadequate experience, process or limited testing budget. In addition, pressure to meet project deadlines or to launch the product to market prematurely may lead to rushed testing and validation, resulting in incomplete or insufficient testing. This can lead to oversight of critical factors, such as reliability, safety, or even regulatory compliance.

A paper from ScienceDirect called “Achieving Agility and Quality in Product Development" discusses the importance of both agility and quality in product development and the critical balance between the two.

Companies must be agile in responding to changing market needs and customer demands. This includes adapting to evolving requirements while incorporating feedback from customers and stakeholders. Additionally, quality in product development, including testing and validation, ensures the product matures in stability and robustness and that the products meet customers' needs, performing as intended.

Verification testing determines whether products built on the manufacturing line meet the expected cosmetic and functional product requirements.  By understanding, identifying, and resolving manufacturing issues before production, you can avoid costly scrap and rework of production units or shipping defective products to customers.

Pitfall #5: Having the wrong team.
When a team lacks the necessary experience, expertise, or cohesion, it can lead to poorly-informed decision-making, which can result in development delays and quality issues. A multidisciplinary team with expertise in areas such as engineering, design, manufacturing, and testing is required for the product development process. A team that is missing essential skills or doesn't function well together can negatively impact the speed and success of the product development process.

Inadequate team composition can be problematic for companies of all sizes. For instance, product development teams in larger organizations may require expertise in innovation frameworks to revamp existing products or create new ones. At the other end of the scale, startups may struggle to attract top talent due to budgetary constraints or lack of brand awareness. These recruiting obstacles and insufficient resources can result in an unbalanced or incomplete team, which can unexpectedly impact product viability.

Consequently, using the wrong team for product development can be a major pitfall. Successful product development entails more than just generating a fantastic idea or creating a unique solution to a problem. Newly-formed teams in established firms or startups may need external assistance in identifying the necessary skills and expertise for product design, testing, manufacturing, shipping, and maintenance.

According to Alira Health's 2023 US Medtech Contract Manufacturing Report, one of the most notable trends in the medical device industry is the growing popularity of Contract Development and Manufacturing Organizations (CDMOs) as the preferred option for medical device firms (both startups and large companies) to outsource talent.

By embracing this trend, companies are discovering exciting opportunities for growth and innovation.
