How to validate a startup idea before you build
42% of startups fail because there was no market need. This guide shows the exact process to validate your idea in weeks — not months — before investing time and money.
The 6 validation steps
Define the problem precisely
Don't start with the solution. Start with the problem: who suffers it, how often, how much does it cost them to solve it today? A well-defined problem is 50% of the validation.
Identify critical hypotheses
A critical hypothesis is an assumption that, if false, kills the business. Example: "Users will pay $19/month for this." List all hypotheses and prioritize the riskiest ones.

Analyze existing competition
If there's no competition, the problem probably doesn't exist. Existing competition is evidence of demand. Your job is to find the gap they don't cover.
Talk to potential customers
20 interviews of 30 minutes are worth more than 3 months of development. Ask about the problem, not your solution. "The Mom Test" by Rob Fitzpatrick is the definitive guide.
Attempt a pre-sale
The best validation is someone paying. A simple landing page with a "pre-register" or "reserve" button tells you more than 100 surveys. If nobody pays, go back to step 1.
Measure and decide: build, pivot, or abandon
With concrete data, the decision is easier. If critical hypotheses validated, build. If some failed, pivot the angle. If the main ones failed, look for another idea.
