GoKawiilJujutsu creator Martin von Zweigbergk becomes CTO of East River Source Control
Martin von Zweigbergk, who built the Jujutsu version control system while at Google, has been named chief technology officer of East River Source Control, a startup developing next-generation version control platforms. He will oversee engineering there while continuing as a core maintainer of Jujutsu, which remains open source under Apache 2.0. ERSC's storage product is set to enter private beta later this month.
GoKawiil's interpretation of the reporting above, not reported fact.
Version control remains foundational infrastructure for software development, and Git's server-side limitations are becoming a bottleneck as AI-driven workflows generate far more code and collaboration activity. Bringing a veteran creator of a widely adopted client-side tool into a commercial venture signals renewed investment in rethinking the remote storage layer, not just the local developer experience.
- Martin von Zweigbergk, Jujutsu's creator, is now CTO of East River Source Control.
- ERSC is targeting the server-side storage layer, which still relies on Git and struggles at scale.
- Jujutsu stays open source under Apache 2.0 even as its creator joins a commercial startup.
Pro Git by Scott Chacon (Apress) — If a version control shakeup like Jujutsu's creator moving to ERSC has you curious about the plumbing under your commits, Pro Git is the classic deep dive into how Git actually works. It walks from everyday branching and merging to internals like objects and refs — exactly the foundation Jujutsu builds on top of.
