LINEAR'S PATH TO PRODUCT-MARKET FIT

Summary from the TLDR Founders newsletter

Karri Saarinen hated Jira so much at Airbnb that he built a Chrome extension to redesign it - 100 coworkers installed it. That hack became Linear, now worth $1.25B. The Finnish founders spent a year validating through bar conversations before building. They gated access obsessively, handpicking 10 users weekly from 10,000 waitlist signups. While competitors chase flexibility, Linear ships opinionated defaults. It hit profitability in 2021 with just 80 employees by choosing quality over growth metrics.
