Jamsocket is joining Modal

Modal has acquired Jamsocket, a backend platform for building synchronization engines for collaborative applications, and Jamsocket co-founders Paul Butler and Taylor Baldwin will join Modal. Jamsocket’s offerings include Plane, an open-source orchestrator; Y-Sweet, a document store and real-time synchronization backend; and ForeverVM, a service providing stateful Python REPLs for AI code execution. The companies cite their shared technical foundations, longstanding relationship in the New York developer community, and growing demand for AI-centric applications as reasons for the move. Jamsocket products will continue operating during a transition in which their core functionality is integrated into Modal, enabling customers to combine GPU inference, code sandboxes, and real-time backends on a single platform.
