Investment Rationale:

When we first connected with Jack, we were immediately impressed by his deep domain expertise in the security data space. He had just spent 3 years at Airbnb as a security engineering manager, where he co-created StreamAlert, a popular open source software that had been in production at Airbnb since 2017.

The two main product innovations that resonated with us were 1) allowing users to write code instead of a UI to create alerts 2) decoupling analysis and data storage. The solutions at the time were limited to archaic interfaces that didn’t give modern security teams the flexibility they needed.
