Build your founder learnings ledger

Build and evolve founder thesis (PMF insights, founder-style, value-hypothesis stance)

When a founder is building their repeatable founder operating system — learning what works, what doesn't, and why.

• · venture learnings, cross-venture patterns, founder reflections, decision rationale

• · updated thesis_ledger.md with PMF insights, founder-style, value-hypothesis entries; patterns across ventures

Founder has completed 1+ ventures and reflected on learnings; willing to abstract and update thesis

• · Thesis stays too abstract (not actionable in next venture)
• · Founder resists updating thesis (sunk-cost bias on old patterns)
• · Cross-venture patterns are cherry-picked instead of systematic

• · Thesis grounded in actual venture outcomes, not philosophy
• · Value-hypothesis stance explicitly tested against PMF failures
• · Pattern evolution documented across time
