The best teams can assemble powerful build and test infrastructure; the hard part is operating it reliably, with visibility and cost control, as demand grows. That is Build Management at AI Scale: operating build and test as production infrastructure, including execution, observability, reliability, and cost control, so teams can build, test, diagnose, and release even as they write code at AI speed. Engineering organizations, including BMW, Databricks, Snap, Canva, Lyft, and Asana, run on EngFlow. The result is high performance at scale. EngFlow was founded by the engineers who created and maintain Bazel, and is backed by Andreessen Horowitz and Tiger Global.
