Hi! We're SubImage, a YC-backed cybersecurity startup. We use graph theory to map out customer environments, helping them find and fix vulnerabilities before they get hacked.

Our tech is built around an open source tool called Cartography that we created at Lyft and donated to the Linux Foundation. It’s used by over 70 companies - including 7 in the Fortune 100 - to make sense of complex infra across AWS, Okta, GitHub, and more.

We're a small, fast-moving team passionate about security, infra, and AI. Before starting SubImage, we've worked at places like Lyft, Anthropic, and the NSA.
