About the Company

Great models are raw ingredients. Kimchi is what happens when you ferment them with good engineering. We started inside CAST AI helping companies run LLMs on their own Kubernetes clusters; today we run our own coding harness on any LLM you pick.

About Kimchi Studio

Studio is where your team’s agents work together: a desktop app that brings autonomous coding agents, model orchestration, and your entire toolchain into one collaborative UI. Multiple agents on separate branches side by side with native git worktree support. Every agent action visible, diffable, and undoable. Local first on your machine, remote sessions when you need them.

You’ll own features end to end: design, implementation, testing, production rollout. Most projects ship in 1-4 weeks. You’ll work directly with product and other engineering teams on problems that don’t have textbook solutions.
