What happened
Martin von Zweigbergk, creator of the Jujutsu (jj) version control system, has joined East River Source Control as CTO. ERSC, backed by Amplify Partners and launched in 2025, is building next-generation version control tooling aimed at scaling challenges driven by AI-assisted development, with ERSC Storage entering private beta later this month. von Zweigbergk will remain a core maintainer of jj as an Apache 2.0 open source project.
Why it matters
If you're evaluating or already using jj, the key takeaway is that the project stays open source under Apache 2.0 while its creator now has commercial backing to solve the server-side storage layer — the Git ceiling that jj currently inherits. Teams hitting scale limits with Git remotes should watch the ERSC Storage private beta, as it targets exactly that bottleneck.
Discussion angle
Is jj worth adopting now that its creator has commercial backing — does this de-risk the project or create a future where the best features move behind a paid product?
