Context is now the product: Product leadership when software can build itself | Karri Saarinen
With Karri Saarinen · Wednesday, September 30, 2026
Linear co-founder and CEO Karri Saarinen delivers a keynote at the Lenny and Friends Summit examining how AI changes product development. He argues that optimizing purely for software output turns companies into low-learning software factories, whereas great products stem from compounding team context, shared judgment, and direct customer connection. Saarinen details Linear's internal practices—including AI-driven customer feedback briefings, Quality Wednesdays, and Feature Roasts—to illustrate how teams can maintain craft and intuition as AI automates execution.
