Who we areEndor Labs is building the Application Security platform for the software development revolution. Modern software is complex and dependency-rich, making it increasingly difficult to pinpoint the risks that truly matter. Endor Labs solves this challenge by building a call graph of your entire software estate—enabling teams to clearly identify, prioritize, and fix critical risks faster. Trusted by companies that are one or one hundred years old, Endor Labs secures code whether it was written by humans or AI, and whether it's 40-year old C++ code or cutting edge Bazel Monorepos. Endor Labs was founded by serial entrepreneurs Varun Badhwar and Dimitri Stiliadis, and is backed by leading VC firms such as Dell Technology Capital, Lightspeed, and Sierra Ventures.Sound interesting?
