A practical method and workbook to compare your team’s assumptions with customer behavior—and decide what to protect, change, or test next.
Every brand has a gap between the customer it was built for and the one who actually shows up. Pick your stage to see what it looks like.
Choose by how much customer evidence you have, not just company size. Each edition has its own tool: Startup’s evidence log works before you have customers, Builder’s churn-call log, Scale’s original-versus-growth comparison, Enterprise’s retention by segment.
