65% of startups fail from co-founder conflict — not bad ideas. FounderLens uses AI micro-expression analysis to build your behavioral profile across 12 dimensions (risk tolerance, conflict style, decision speed, work intensity + more). Share your code with a potential co-founder, do a 10-min video assessment, and get a full compatibility report with strengths, friction points, and actionable advice. Free to assess yourself. $19 for the compatibility report when it actually matters.

Hey PH! 👋 I built FounderLens after watching two close friends burn their startup to the ground — not because the idea was bad, but because they had completely opposite conflict styles and never knew it until it was too late. Most co-founder matching is just LinkedIn for founders. FounderLens goes deeper: you record yourself answering 8 behavioral questions on camera, and AI analyzes your micro-expressions, stress responses, and emotional patterns to build a real behavioral profile. The free assessment takes ~10 minutes. The $19 compatibility report unlocks when you actually compare with someone — so you only pay when the stakes are real. Would love brutal feedback from this community. What would make you trust (or not trust) a tool like this when choosing a co-founder? 🙏
