Feasibility
How to analyze the viability of a business — in three questions
Business viability is not one yes/no. It is desirability, viability, and feasibility. Here is how to read all three before you commit time or money.
“Is my business viable?” feels like a single question with a single answer. It isn't. Viability is a stack of three different questions, and founders get into trouble when they answer one of them confidently and assume they've answered all three. You can have a product people love that never makes money. You can have a profitable model nobody wants. Each layer can pass while another quietly fails.
The three layers of viability
- Desirability — do real people want this badly enough to change what they do today?
- Viability — if they do, is there a believable path to money that exceeds what it costs to serve them?
- Feasibility — can you actually build and deliver it with the time, skills, and money you have?
Order matters. There's no point modelling unit economics for a product nobody wants, and there's no point checking whether you can build something that, even built, won't pay for itself. Start at the top and only descend once a layer holds.
Most failures are desirability failures wearing a viability mask
Founders love to blame pricing, costs, or “the market wasn't ready.” Usually the truth is simpler: not enough people wanted it. Check that first, honestly, before you blame the spreadsheet.
What an honest viability read looks like
A real viability analysis doesn't end in a thumbs-up. It ends in a list: here is what's strong, here is the assumption that scares me most, and here is the cheapest test that would tell me if I'm wrong. The goal isn't a verdict — it's knowing which risk to attack first.
- Name the customer precisely — not “small businesses,” but a person you could call this week.
- Write down what they do today and what it costs them in time, money, or stress.
- Estimate one number: what could a customer be worth to you per year, minus what it costs to serve them?
- List the one thing that, if false, ends the business — and decide how you'd test it for under €100.
