Butter is joining Modal

Modal has acquired Butter, bringing founder Erik Dunteman and researcher Raymond Tana onto its Sandbox team to help expand Modal Sandboxes. Butter’s work has focused on agent harness engineering, including computer-use agents, deterministic memory systems, skills, code generation, and bVisor, a lightweight ephemeral sandbox powered by a virtual Linux kernel written in Zig. Modal expects the team’s expertise to strengthen its sandbox product, while Dunteman argues that code generation can improve AI agent systems through greater determinism, auditability, and fine-grained permissions. The acquisition also builds on Dunteman’s prior relationship with Modal, which began during his time cofounding serverless GPU platform Banana and later included a brief contracting role at Modal.
