Sequoia's David Cahn argues that great founders never think sequentially. Published February 11, 2026, the essay maps startup building onto chess: an Opening phase covering inception and early hiring, a Midgame phase beginning at product-market fit, and an Endgame phase defined by a long-horizon vision. Most founders treat these as stages to pass through. The best run all three concurrently.
The framework earns its weight through specifics. Clay, nearly ten years old, still radiates an 'early days' opening energy. RunwayML showed midgame traction through open-source growth years before Stable Diffusion validated the category. Anduril created a sense of inevitability from day one. Alex Wang at Scale and Crusoe's pivot from crypto miner to AI infrastructure builder are Cahn's evidence that simultaneous phase awareness produces resilience, not confusion. The structural traps are equally concrete: a weak endgame story kills fundraising without traction, a strong opening story breeds premature hubris, and deep tech's 'valley of death' exists precisely because a compelling endgame guarantees nothing about surviving the midgame.
The piece is worth reading in full because the chess analogy does real analytical work rather than decorative work. Cahn ties each phase to a prophet, Paul Graham for the Opening, Elon Musk for the Endgame, and notes that board members exist specifically to transmit inter-generational midgame knowledge. The operational prescription is direct: apply all three lenses to every product decision, every hire, every investor pitch, regardless of your current stage. The argument is not motivational. It is architectural.
