Why most startups fail: building something nobody pays for

Executive overview

Most startups fail not because of bad execution, but because they build something nobody wants to pay for. Developers and product people default to building because it feels safe — but skipping customer validation is where companies die.

Start with a problem a business already knows it has. Then design a solution. Write software last.

Building something people pay for requires doing the hard, uncomfortable work before writing a single line of code.

The two failure modes

• Building something people use but won't pay for (free tools, tip-jar economics)
• Building something nobody wanted in the first place — starting from an idea, not a problem
• Consumer products require near-zero marketing costs and low price points; B2B is far more repeatable to bootstrap
• Businesses pay more, churn less, and can articulate the problems they need solved

How to avoid building the wrong thing

1. Start with a specific problem a business has — and ideally one they've already tried to solve
2. Validate the problem in conversations before building anything
3. Don't aim for novel — a simple twist on a clunky competitor is enough
4. Wherever businesses use Excel or Google Sheets, there's a B2B SaaS opportunity
5. Avoid comfort-zone work (redesigning the homepage, adding features); prioritise customer conversations and assumption-testing

The second most common failure

• Even founders who build something businesses want expect the product to sell itself
• "Build it and they will come" almost never happens
• The best product rarely wins — the best marketing and sales does
