Linear is a project and issue tracking system used by top growth companies like Block, Vercel, and Ramp. Karri shares Linear's unique approach: no A/B testing, minimal product managers (just one head of product), teams organized around projects rather than functions, and a deep commitment to craft. The company achieved profitability within two years and maintains a net negative lifetime burn rate. Key themes include the importance of design as a market differentiator in crowded spaces, building opinionated software, working in focused cycles, hiring for product sensibility across all roles, and growing through selective early-stage customer focus before expanding upmarket.", "key_frameworks": [ "The Linear Method", "Design as a Core Differentiator", "Opinionated Software Philosophy", "Cycles (vs. Sprints)", "Product-Focused Hiring", "Paid Work Trials", "Cohort-Based Beta Launch Strategy", "Segment-Based Product-Market Fit" ] }, "topics": [ { "id": "topic_1", "title": "Design Mattering More in Crowded Markets", "summary": "Karri explains how as markets mature and new paradigms emerge (web, mobile), the importance of design increases.
