Founders say
Validate first, build second
7.8/10
“The competitor breakdown alone saved me from building into a bloodbath market. I saw CoachUp was the main competitor and found their exact weakness — mobile UX. Pivoted my pitch on that and landed 40 beta users in week one.”

8.2/10
“12 ideas validated in 3 months. The 30-day plan is genuinely scary accurate. My last idea scored 8.2 and we're now at $8K MRR after 6 weeks — exactly as the revenue math predicted.”

6.9/10
“The validation experiments tab changed how I work. Ran a $40 Facebook test exactly as suggested — confirmed demand before building anything. Saved me 3 months and probably $15K.”
