About the Company

General Magic

AI agent development and deployment platform

OpenSesame provides a platform to speed up the creation, deployment, and testing of AI applications. Its core feature is a prompt-to-agent algorithm that, from a user prompt, automatically assembles the full backend infrastructure and toolchain needed to run an AI agent, often in seconds. The system lets developers test agents in real time within the OpenSesame environment. The service streamlines the developer workflow by handling infrastructure and deployment tasks, so engineers can focus on the agent’s functionality. Positioned as a platform-as-a-service, it likely uses tiered or usage-based pricing, targeting AI developers and companies who want to rapidly prototype and launch AI-powered applications. OpenSesame was founded in 2024 by Abhinav Lalam and Rohan Kene and is part of the Y Combinator Summer 2024 cohort. Its goal is to make AI application development more accessible and efficient by automating backend setup and testing.
