Grassion

Measure whether your AI coding tool spend (Copilot, Cursor, Claude Code) is actually paying off.

Grassion is a GitHub App that detects AI-generated PRs automatically (via commit trailers and PR labels), tracks what happens to them after merge (reverts, rework, hotfixes, CI failures), and produces a weekly email + dashboard showing the ROI verdict in plain English.

Target buyer: founding engineers and CTOs at 5–25 dev startups. Price: $29/dev/month.
