The Problem
Most Founders Bet on the Wrong Idea First
early-stage founders pivot or abandon their first idea within 12 months.
— First Round Capital / CB Insights founder research
Too Many Ideas, Zero Signal
You're sitting on 5–10 concepts. Every one feels promising. Nothing tells you which to bet on.
Generic Validation is Worthless
Business plan generators give you structure, not answers. ChatGPT gives you confidence, not evidence.
Months Lost to the Wrong Bet
The average founder spends 6–14 months on a product nobody wants before pivoting.
