Know If Customers Will Buy
Before You Write a Line of Code
42% of startups fail because they build something nobody wants. will.it.sell gives you purchase intent data from 100+ synthetic consumers in under 5 minutes - for the cost of a coffee.
The Validation Gap for Solo Founders
Focus groups cost $7,000-$20,000. Surveys take weeks. Solo founders have neither the budget nor the time. So they skip validation entirely - and 42% build something nobody wants (CB Insights).
First-time founders have only an 18% success rate. The founders who beat those odds are the ones who validate before they build - not after.
The Old Way vs. The New Way
Same quality of insight. Fraction of the cost and time.
