The team

The people who break it, build it.

A small, senior team that has spent careers on both sides of the breach: offense, defense, operations, and applied AI. The co-founders are public. The rest keep a low profile. Their work doesn't.

The ask

One repo. One target. One unattended review. Exploitable findings.

No slides, no sales pitch. You talk to a researcher who does this work. Point us at a system you own, even your hardest environment, and we hand back validated, exploitable findings, each one proven. If there's nothing worth your time, you'll know that too. Either way, you know where you stand.
