We got tired of test suites nobody trusted anymore.

Every team we talked to had the same ritual: a red test suite every Monday morning, a developer spending an hour figuring out whether a failure was a real bug or a locator that broke because someone renamed a CSS class.

Eventually, the team stops looking closely. Failures get waved through, a real regression slips past review, and the whole point of having tests quietly evaporates.

Nerro Labs exists to fix the trust problem, not just the coverage problem — visual AI that tells you exactly what changed, and self-healing that keeps a test alive through the kind of change that shouldn't break it in the first place.

We're a few months in, pre-seed, and still tuning the matching models against real UIs from our first design-partner teams. What's in the product today is rougher than we'd like — that's what building it with real engineering teams looks like.
