Idea

A developer tool that runs only the tests affected by your Git changes, saving CI/CD time and providing receipts for what was tested. Reduces test execution time for teams with large test suites and helps developers move faster without worrying about missing coverage.

Why this is interesting

Test suite bloat is a real and growing pain point as codebases scale, and the shift toward trunk-based development and faster deployment cycles has made slow CI pipelines a bottleneck that engineering managers now actively budget to fix. Launchable and Gradle's Develocity are the closest incumbents, though both target JVM ecosystems primarily and carry enterprise pricing that leaves the Python/pytest ecosystem underserved. The $1k–5k/mo revenue band is plausible for a self-serve tool sold to small engineering teams, but it's a ceiling that's hard to break through without a clear expansion motion — per-seat or per-CI-minute pricing could help, but most developers will resist paying much for something they half-expect their CI provider to eventually bundle. The biggest risk is commoditization: GitHub Actions, CircleCI, and pytest plugins like `pytest-testinfra` or community forks could absorb this functionality quickly, and a single well-maintained open-source project would likely kill willingness to pay entirely.
