API Key Breach Monitor

Developers accidentally expose API keys in git repos and env files, causing security breaches and unexpected billing. A tool that scans repositories, monitors for exposed secrets, and alerts users immediately when keys are leaked. Target users are startups and small teams managing multiple services.

GitGuardian already owns this space and has a well-funded, mature product doing exactly this, with a free tier that captures most of the small-team use case. GitHub itself added native secret scanning to all public repos in 2022 and extended it to private repos for paid plans, which further narrows the addressable gap. The revenue band is unclear because the core value proposition is safety rather than productivity, and small teams historically resist paying for security tooling until after a breach — making conversion friction high even if detection works well. The most likely failure mode is not technical but commercial: getting crushed between a free GitHub native feature and an established competitor before reaching the paying customer volume needed to sustain the business.
