# Xin Ding

> Xin Ding is the cofounder and CEO of Attune (YC X25), a San Francisco startup building blazingly fast, drop-in build tools that speed up compilation without any migration effort. After more than a decade shaping developer-tools products - as Head of Product at FOSSA and VP of Product at Teleport, where he helped scale the company to unicorn status - he teamed up with longtime colleague Eliza Zhang to attack one of the least glamorous but most universal engineering headaches: slow builds. Attune's first product lets Rust developers prefix an existing command with 'hurry' to get dramatically faster builds through distributed caching, remote execution, and compiler-native optimizations.
