## Notes
- Verbatim LinkedIn post on joining Cognition: "Today, Corridor is joining Cognition! Together, we’ll be taking Devin Security to the next level.

The next 6-12 months represent the most consequential period in the history of cybersecurity. AI agents can now run end-to-end attacks, mostly by exploiting vulnerabilities we’ve known about for decades.

Fortunately, defenders can use the same capabilities to root out exploitable vulnerabilities before attackers find them. For the first time, it’s possible to not just patch vulnerabilities one at a time, but systematically eliminate them at the source, making Secure by Design a reality.

Fixing vulnerabilities is fundamentally a software engineering problem, which is why we’re so excited to join forces with Cognition.

The past two years have been a whirlwind, and I’m incredibly grateful to our team, our customers, and our investors for the support along the way. I can’t wait to show you what we build next." This frames his Cognition remit as remediation at scale (Secure by Design made real), not just detection.

We started Corridor almost two years ago with the mission of accelerating secure and autonomous software development. Since then, we’ve seen security go from a niche concern to one of the most pressing issues of our time.

We’re grateful to our team, our customers, our investors, and everyone who’s supported us along the way. We can’t wait to show you what we build next!" (https://x.com/jackhcable/status/2115873282662732215)
