Butter is an artificial intelligence infrastructure startup that develops bVisor, a lightweight sandbox runtime designed to provide a secure local execution environment for autonomous AI agents interfacing with business applications. The software platform embeds directly into local processes to offer a safe bash environment, effectively eliminating the computational overhead and latency typically associated with traditional virtual machines or remote infrastructure. Currently operating with a lean team of two employees, the early-stage company was selected to participate in the Y Combinator Winter 2025 accelerator batch under the guidance of primary partner Jared Friedman. The technology targets engineering teams building agentic workflows, drawing on the founder's prior experience developing infrastructure at Modal.com and Banana.dev, a serverless GPU platform previously utilized by over 3,000 artificial intelligence teams. Butter was officially founded in 2024 by chief executive officer Erik Dunteman.
