Linear’s aggregated data from paid workspaces shows AI use spreading across software-team functions and correlating with higher software-development activity through 2026. From January to June 2026, the share of users active on Linear AI features more than doubled in every measured function: product rose from 12% to 34%, engineering from 12% to 30%, design from 6% to 22%, and go-to-market from 5% to 18%. Adoption was similar across company sizes, while CEOs at companies with 201 or more employees increased from 9% to 36%. These figures cover AI interactions inside Linear, including in-app and Slack conversations and agent sessions, rather than all AI use. AI agents and MCP created 2.435 million Linear issues in the week of August 3, 2026, compared with 2.481 million created by people and integrations. Pull requests opened per workspace were 111% above the June 2024 baseline by June 2026. In a fixed cohort, workspaces connected to coding agents rose from 21 to 65 pull requests per team per week over two years, while teams without a connected agent rose from 8 to 10. The share of product users attaching pull requests increased from 3% in June 2024 to 10% in June 2026, and designers rose from 1% to 8%. Linear found that time spent on existing coordination work generally increased or held steady, while AI chat and agent work added new activity; it does not measure whether the added output produced positive business outcomes.
