Hey Product Hunt! I'm the maker of KaizenLab — a free hypothesis validation platform for product teams. **Why I built this:** When building products, the hardest part isn't coding — it's knowing whether you're building the right thing. I wanted a structured way to go from "we think this might work" to "we have evidence this works," without scattered spreadsheets and docs. **What makes it different:** - **Hypothesis Canvas** — A Lean Canvas-inspired framework to structure your problem, hypothesis, validation method, and success metrics in one place. - **AI Review** — AI analyzes your canvas for gaps, suggests improvements, and runs competitor analysis. - **Verification Tracking** — Track the Build-Measure-Learn cycle in real time with status tracking per hypothesis. - **PMF Dashboard** — Auto-aggregated verification results with a real-time PMF score. - **Team Collaboration** — Real-time co-editing, comments, and mentions to keep everyone aligned. It's completely **free** — no credit card required. I'd love to hear your feedback, especially from product managers and startup teams running hypothesis-driven development!
