Turn a Startup Idea Into a Validated Business
An idea is the starting point. A validated problem is the foundation
Most ideas don't fail because they were built badly. They fail because they were built for a problem that wasn't real enough, for a customer who wasn't ready to pay.
Why ideas don't become companies
- The problem is mildPeople agree it's annoying, but not enough to change what they do or pay to fix it.
- The customer is everyoneWith no first customer, there's no first channel, no first price and no first product.
- The build came firstMonths go into software before a single assumption is tested with a real person.
- The founder fit is unclearThe idea needs access, skills or distribution the founder doesn't have yet.
The validation journey
Research first, then the smallest test that could change your mind.
Write the problem, the customer and the outcome in one paragraph each.
Problem briefDesk research on the market and alternatives, labelled as desk research.
Evidence logConversations with potential customers about their problem, not your idea.
Patterns, not quotesA concierge service, landing page or prototype to test the riskiest assumption.
Result recordedAdvance, investigate further, pivot or stop.
Decision memoAssumptions worth testing
- Audience. Clinic owners will try a new booking tool without a referral
- Problem. Missed appointments cost them more than the tool would
- Opportunity size. There are enough independent clinics in one city to start
- Capability. We can integrate with the systems they already use
- Founder fit. The founder can get into a room with clinic owners
Where it can lead
Each outcome is a good one, because each one saves you from building the wrong thing.
