Help us build the data security layer for the AI era

We're building data protection that works everywhere sensitive information moves in the enterprise—across AI tools, SaaS apps, endpoints, and email.
Helping everyone from startups to Fortune 500 enterprises protect their data

Our purpose

We believe data protection has to work intelligently and invisibly, or it won't work at all. Security teams shouldn't need to stitch together five different tools, wade through endless false positives, and still miss critical events. We're building toward a future where any company—from a 50-person startup to a Fortune 500—can protect their sensitive data across every SaaS app, every AI tool, and every endpoint without slowing anyone down.

Who we are

Founded by an early Uber Eats engineer and investors from Venrock and Bain Capital Ventures, we are a team of machine learning engineers, security practitioners, and product builders with experience spanning Uber, Harness, Microsoft, Symantec, Code42, Rubrik, and Skyhigh Security.
