Why Commercial Viability Matters More Than Technical Feasibility
A prototype that works in the lab is not a business. Investors know it, and the founders who raise well know it too.
For an investor, commercial viability is a different question from technical feasibility. Technical feasibility asks: can we build it? Commercial viability asks: will anyone pay for it, and can we make money doing so?
The distinction matters because the two paths diverge sharply. A technology that's technically brilliant but commercially unviable will consume capital, talent, and time, and still collapse.
At P1 Carbon Solutions, we help advanced engineering ventures overcome the critical Valley of Death between innovation and market viability. The ventures that survive are not always the ones with the best technology. They are the ones that can evidence the commercial case before an investor asks for it.
Pro Tip: Start with commercial assumptions, not technical ones. Ask whether customers exist, whether they'll pay your target price, and whether you can deliver at that price profitably. If any answer is uncertain, that's your starting point for investigation, not a problem to solve later.
What Investors Will Actually Test
A serious investor will not take a commercial case on trust. Expect them to probe six things:
Quality of demand evidence. Commitments with money or time behind them, not positive conversations.
Cost at volume. Whether unit cost is modelled at production volumes, or extrapolated from prototype quotes.
Capital to break-even. How much cash the venture needs before it stops consuming it, and what that buys at each stage.
Time to revenue. How long customer qualification and production approval will take in your sector.
Supply chain exposure. Single-source components, supplier capacity and who owns the tooling.
Sensitivity. What happens to the case if price, volume or a key input cost moves by 20 percent.
The rest of this guide covers how to build the evidence for each.
Conducting a Commercial Viability Assessment
A commercial viability assessment is a structured examination of whether a product or service can generate sustainable revenue at scale. It's not a business plan. It's the foundation that a business plan sits on. Think of the work in three layers: the assessment asks whether there is a case at all, market and financial analysis size it, and a feasibility study tests it against reality.
The assessment answers three core questions:
Does a real market exist for this product?
Can we reach that market affordably?
Can we build and deliver it profitably?
Defining Your Target Market and Customer Base
Before you can assess viability, you need to know who you're selling to. Not a vague category, but specific customers with specific needs.
Define your target market by:
Primary customer: Who makes the purchase decision?
Problem they solve: What pain point does your product address for them?
Current solution: What are they using now, and why is it inadequate?
Budget authority: Does the person who feels the pain also control the budget?
Purchase cycle: How long is their decision process, and what triggers it?
Many teams skip this step and assume the market is obvious. It rarely is. A composite material that works beautifully for automotive might have no path into aerospace, even though both industries use advanced materials. The procurement processes are different. The cost targets are different. The validation requirements are different.
Validating Demand Before You Scale
Demand validation is not a survey. Surveys ask people what they want. Demand validation shows what they actually do.
Real demand signals include:
Customers willing to fund development or trials
Signed letters of intent or framework agreements
Pre-orders or commitments to purchase
Participation in pilot programmes with clear evaluation criteria
Willingness to change existing processes to adopt your solution
Weak demand signals include:
Positive feedback in conversations
Interest in learning more
Statements that your product "would be useful"
Attendance at your pitch meeting
The gap between those two lists is where many ventures come unstuck. They confuse politeness for commitment. A potential customer saying your solution is interesting is not the same as them betting their budget on it.
Watch Out: Do not scale production based on verbal interest. Demand validation requires skin in the game: money, time, or formal commitment. Without it, you're building inventory for a market that may not exist.
Market Viability Analysis: Sizing the Opportunity Honestly
Market viability analysis examines whether the market you've identified is large enough, accessible enough, and growing enough to justify your investment.
Start with market sizing. Many teams overestimate their addressable market. They look at a global industry and assume they can capture a meaningful slice. They rarely can.
Break market sizing into three tiers:
Total addressable market (TAM): The theoretical maximum if you captured every possible customer
Serviceable addressable market (SAM): The portion you can realistically reach given your geography, distribution, and resources
Serviceable obtainable market (SOM): Your realistic market share in year three or five
Most ventures can articulate their TAM. Few can honestly assess their SOM. That's where reality lives.
Assess market dynamics by examining:
Growth rate: Is the market expanding or contracting?
Competitive intensity: How many players already serve this market, and how entrenched are they?
Barriers to entry: What stops new competitors from entering? (Price, scale, regulation, relationships, technology)
Customer concentration: Are sales concentrated among a few large buyers, or distributed across many?
A large, growing market with weak barriers to entry is attractive to competitors. You'll face price pressure. A smaller market with high barriers is less attractive to competitors but harder to enter yourself. The ideal is a market growing faster than competitors can scale to meet it.
Key Takeaway: Market size alone doesn't determine viability. A small market with high barriers and a clear path to profitability is more valuable than a large market where you're one of fifty competitors fighting on price.
Financial Viability Assessment: The Numbers That Matter
This is where many engineering teams go silent. Financial viability sounds like spreadsheet work. It is. But it's also the only objective measure of whether your venture survives.
Unit Economics and Cost Structure
Unit economics are the foundation. They answer: what does it cost us to make one unit, and what can we sell it for?
Build your cost structure by layer:
Material costs: Raw inputs, components, sub-assemblies, priced at production volumes and minimum order quantities, not prototype costs
Direct labour: Hands-on production work
Manufacturing overhead: Facilities, equipment, utilities allocated to production
Tooling and up-front engineering: Moulds, fixtures and development costs, spread over realistic volumes rather than hoped-for ones
Quality and testing: Validation, certification, rework
Logistics: Storage, handling, shipping to customer
Sum these to get your cost of goods sold (COGS) per unit. Then determine your gross margin: the difference between your selling price and COGS.
There is no universal target. A differentiated technology product can command far higher margins than a component supplier, whose margins are often thin and subject to annual price-down demands from OEMs. The real test is whether your margin covers operating costs, warranty exposure and the price reductions customers will expect over the life of a contract, with headroom to spare.
The hard part is getting accurate cost data. Many teams use supplier quotes for components but underestimate manufacturing overhead, quality costs, and logistics. They build a financial model that looks viable, then reality arrives and margins collapse. Prototype quotes are a particular trap: they rarely reflect production volumes, minimum order quantities or the price breaks a supplier will actually commit to.
Pathway to Profitability
Unit economics tell you whether individual sales are profitable. Pathway to profitability tells you whether the business reaches profitability at scale.
Calculate your break-even point: the sales volume at which total revenue equals total costs. This requires:
Fixed costs: salaries, facilities, insurance, administration (costs that don't change with volume)
Variable costs: COGS plus costs that scale with production
Selling price per unit
Many ventures underestimate fixed costs. A team of five engineers, a facility, compliance infrastructure, and supply chain management all cost money whether you're producing one unit or one thousand.
Then ask: at what volume do we reach break-even, and how long does it take to get there?
A venture that reaches break-even at 50,000 units annually and can achieve that volume in year two is very different from one that needs 500,000 units to break even and won't reach that volume until year five. The second requires significantly more capital to survive the journey.
Two things stretch that journey further than most models allow. The first is customer qualification: in automotive and similar sectors, validation and production approval can add 18 months or more before meaningful revenue. The second is working capital: OEMs commonly pay on 60 to 90-day terms, while early-stage ventures often have to pay suppliers up front. A venture can make a profit on every unit and still run out of cash.
Conducting a Commercial Feasibility Study Before Investment
A commercial feasibility study is a deeper investigation. It goes beyond assessment to test your core assumptions against reality.
A feasibility study typically includes:
Customer interviews: Detailed conversations with target customers about their needs, purchasing process, and willingness to adopt
Competitive analysis: Who else serves this market, what are they doing, and where are the gaps?
Regulatory and compliance review: What certifications, approvals, or standards apply?
Supply chain mapping: Can you source materials reliably at your target cost and volume?
Financial modelling: Detailed projections of costs, revenue, and cash flow under different scenarios
Risk assessment: What could go wrong, and how would you respond?
This is not theoretical work. It's investigative. You're testing whether your commercial assumptions hold under scrutiny.
Many teams resist this step because they fear bad news. They worry that a feasibility study will reveal fatal flaws. Sometimes it does. That's valuable information. Finding out your market doesn't exist before you've spent three years and ten million pounds is a win, not a failure.
Ventures that have done this work early are easier to back. Investors know that founders who've tested their assumptions are more credible than those who haven't.
In Practice: A clean-tech infrastructure venture had a validated concept and grant-funded demonstrators, but funders wanted to know who would build it, and at what cost. Our founder mapped fabrication capability across several countries, built a three-scenario manufacturing cost model and ran an RFI across seven fabrication suppliers. The result: multiple letters of intent with tier-one shipbuilders and marine fabricators, and a cost range funders could test.
Common Pitfalls in Commercial Viability Evaluation
Even experienced teams make predictable mistakes when assessing commercial viability. Knowing them helps you avoid them.
Confusing technical achievement with market demand. A prototype that works is impressive. It's not evidence of market demand. Teams often assume that if they build it well enough, customers will come.
Underestimating the cost of reaching customers. Getting your first customer is expensive. Sales, marketing, relationship building, and proof-of-concept work all cost time and money. Many financial models assume customers arrive organically.
Assuming your cost structure will improve at scale. Sometimes it does. Often it doesn't. Capacity comes in steps rather than smoothly, suppliers re-price above volume thresholds, and yield losses during ramp-up can absorb the savings you expected.
Treating market size as fixed. Markets shift. Regulations change. Competing technologies emerge. Your market analysis is a snapshot, not a forecast. Build flexibility into your strategy.
Watch Out: The most dangerous pitfall is confirmation bias. You've invested time and emotion in your idea. You unconsciously filter information to support it and dismiss evidence against it. Bring in external perspectives. Seek out the strongest objections to your plan, not the weakest.
Building a De-Risked Operational Roadmap
Once you've assessed commercial viability, the next step is building an operational roadmap that de-risks your path to scale.
A de-risked roadmap doesn't eliminate risk. It identifies the biggest risks and sequences your work to test them early.
Your roadmap should address:
Supply chain validation: Can you source at volume? Are suppliers committed? What's your backup plan?
Manufacturing process: Have you validated your production method at near-commercial scale? Do you have process documentation?
Quality and compliance: Do you understand the regulatory landscape? Have you achieved necessary certifications?
Customer integration: Have you worked with customers on integration? Do they understand what's required on their end?
Financial sustainability: Have you modelled cash flow realistically? Do you have a clear path to profitability?
Sequence these by risk and dependency. Evidence demand first, de-risk the supply chain before you commit capital, and validate customer integration before large production runs. Our guide to crossing the Valley of Death sets out these milestones in more detail.
This is where many ventures struggle. They're optimised for technical progress. They're not optimised for commercial risk reduction.
Conclusion
Commercial viability is not a single exercise. It's a discipline that runs through every stage of your venture's development.
The assessment starts with honest questions: Does a real market exist? Can we reach it? Can we make money doing so? Investors will ask all three. The ventures that raise well have the evidence ready before they are asked.
P1 Carbon Solutions works with engineering ventures to build that evidence: cost at volume, supply chain strategy and commercial terms that stand up to investor and OEM scrutiny. If you are preparing for a raise and want an honest view of where your commercial case is weakest, get in touch.
