Crucible moments make companies. Sequoia’s Alfred Lin on how Airbnb, DoorDash, and Zappos won when it mattered most. In this conversation: * infinite games, first-order issues, and the daily inputs that compound into edge * zappos from zero sales after 9/11 to $1.6B: cash discipline, flow over batching, and world-class service * the counterintuitive truth about returns: your best customers might return the most—and why that’s good * airbnb’s trust problem: removing friction with Instant Book and how “fringe” becomes mainstream * doordash’s suburban wedge: be different (and right), density where others don’t look, and sequencing expansion * hiring for slope, not intercept: potential over pedigree, and how to reduce regrettable turnover * force vs. obstacle removal: when to push, when to redesign the system, and how boards actually help * compounding advantage: CAC paid back on day one, repeat-first growth, and free cash flow equals freedom what you’ll learn * a first-order issue checklist to find root causes fast * the “slope, not intercept” hiring screen that predicts who scales * how to turn high returns into higher LTV (without killing margin) * a playbook to remove marketplace friction (trust, time, and instant confirmation) * a wedge strategy you can copy: start where value is highest and density is hidden About Alfred Alfred Lin is a partner at Sequoia Capital and former COO/CFO/Chairman of Zappos.
