Sequoia Passed on DoorDash—Then Led Its Round: How Alfred Lin Evaluates Startups | Product-X

Exploring unknown technologies. Decoding tomorrow's unicorns. Welcome to Product-X. In this new series, we turn the camera toward the venture firms and partners behind ambitious startups. Our first episode focuses on Sequoia Capital's Alfred Lin. How have his mathematics and statistics background—and his operating experience at LinkExchange and Zappos—shaped the way he evaluates founders, customer retention, and scale? Through Sequoia's initial rejection of DoorDash and subsequent investment, the timeline of its Airbnb partnership, and its investment in legal AI company Harvey, we explore how a partner's experience translates into investment judgment. Vivian examines capital and business strategy; Nolan explains operating metrics and technical validation. Analysis based on public examples should not be mistaken for a complete account of Sequoia's internal investment criteria. Chapters: 00:00 Sequoia passed on DoorDash.
