We got tired of meeting bugs in the incident channel.
Ferret is built by two infrastructure engineers who spent a decade on call. We think a bug finder should earn your trust the same way a colleague does: by being right and showing its work.
Catch the defect while it is still cheap.
A bug found in the branch that introduced it costs a code review comment. The same bug found in production costs an incident, a rollback, a postmortem, and a night of someone's sleep. The gap between those two numbers is enormous, and almost all of it is avoidable.
The reason it is not avoided is simple: catching the bug early means executing the edge case, and people reviewing code do not execute anything. So we built a hunter that does. Ferret reads the code, runs the corners nobody ran, and when it finds something real, it hands you a failing test and a fix instead of a shrug.
The goal is not more findings. It is fewer 3:47am pages.
Two engineers, one pager between them.
Jordan Vance
Co-founder, CEO
Spent eight years on platform and reliability teams, most of it holding the pager. Built incident tooling that everyone loved and nobody wanted to need. Wanted the bug caught before the page.
Priya Nair
Co-founder, CTO
Infrastructure engineer turned program-analysis nerd. Worked on build systems and test infrastructure at scale, where she learned that a test you can run beats an opinion you can argue with.
Ferret Labs, Inc. is a remote-first company headquartered in Boulder, Colorado.
Four things we do not compromise on.
A test or it did not happen
We do not ship warnings. Every finding is backed by a reproduction that fails on your real code. If we cannot write it, we do not send it.
Signal over volume
A tool that flags a hundred things flags nothing. We would rather surface three real defects than bury them in a report nobody reads.
Your code is yours
Isolated sandboxes, never trained on your source, self-host when you need it. The boundary is a feature, not a footnote.
Engineer to engineer
We build for the person who gets paged. No hand-waving, no dashboards that impress executives and help no one.
Come hunt with us, or put us to work.
We are a small team of engineers who like hard problems and quiet pagers. Try Ferret on a repo, or reach out if you want to build it with us.
