A better way to plan, build, and ship products | Ryan Singer (creator of “Shape Up")

Ryan Singer, creator of Shape Up and former Head of Strategy at 37signals, explains why appetite-driven timeboxing beats Scrum and when companies should switch.

• Shape Up emerged from DHH working only 10 hours/week on the first Basecamp, forcing extreme discipline about what to build and when to ship.
• The core inversion: set a fixed appetite (max 6 weeks), then vary scope — never extend the timeline.
• 30–50 people in product and engineering combined is the typical breaking point when informal startup speed collapses.
• Most teams misapply Shape Up by skipping shaping — handing engineers a PRD or Figma file instead of a technically-vetted concept.
• Basecamp’s hidden advantages: every designer codes, founders stayed in problem definition until 2021, zero sales team pressure on engineering time.
• If a project isn’t done at cycle end, move it back to shaping mode rather than extending — almost no teams use the book’s circuit-breaker rule literally.
• In Shape Up the PM role shifts upstream: less sprint-shepherding, more narrowing the problem and negotiating scope before any build begins.
• Singer’s practical entry point for demand-side framing: Bob Moesta’s Demand-Side Sales 101, more tactical than Competing Against Luck for running struggle interviews.
