Lean Startup / customer development works great until you try to actually keep track of what we've validated. Our Assumptions get written down, interviews summarized, experiments run, learnings captured… then everything gets hard to track. Spreadsheets are a bit clunky, Notion seems overkill for this use case, and three months later it's hard to track why we pivoted or dumped an idea. We built ourselves a dead-simple single-page board just to stop losing that history: idea → segment → pain → hypothesis → riskiest assumption → validation method → execution → actual learning. Nothing fancy, no bloat. Before I assume that's a common pain, I'd rather hear from people who do this stuff more than I:
Could you walk me through the last time you ran real validation (customer convos, tests, etc.). How did you actually record and organize what you learned? What was the hardest/annoying part about keeping it all together as things moved fast? What have you tried so far (spreadsheets, Notion, physical notes, rituals, apps, whatever) and where did it break down?
Stories welcome, no sales pitch coming, just trying to understand if this is worth polishing further. Thanks!
