Linear is a project management and issue-tracking platform built specifically for software engineering and product teams. It lets developers, PMs, and designers plan, track, and ship software through a fast, keyboard-first interface that integrates tightly with GitHub, Slack, Figma, Sentry, Cursor, and Codex. Core features include issue tracking, sprint cycles ("Cycles"), roadmaps, and AI-powered triage. In 2026, Linear launched "Linear Agent" — a workspace-aware AI that can parse Slack threads, customer support conversations, and call transcripts to automatically create and route structured issues. Founded in 2019 in San Francisco, Linear is used by more than 40,000 companies including OpenAI, Coinbase, and Ramp. It runs a product-led growth model with a free tier, paid plans at $10–$16/user/month, and is now adding a structured enterprise sales motion on top. The platform's core competitive edge is raw speed and opinionated simplicity: teams adopt it in minutes, and engineers actually use it voluntarily — a rare outcome in PM tooling.
