Projectx

ProjectX is a San Francisco-based Y Combinator (Spring 2026) startup building Infinity (InfinityOS), a cloud operating system designed for AI agents. Infinity lets agents and humans orchestrate GPU workloads through a chat interface rather than traditional APIs, running multiple Windows and Linux applications — such as Blender, VS Code, DaVinci Resolve, Unreal Engine, and Isaac Sim — simultaneously, each on its own independent compute and GPU inside a single shared browser-based workspace with sub-minute cold starts. A public API, developer docs, status page, changelog, and blog are announced as coming soon; no programmatic API surface is published yet.

Projectx is profiled on the APIs.io network. Tagged areas include Company, Cloud, Operating System, AI Agents, and GPU.

Projectx’s developer surface includes documentation, pricing, support, signup flow, and 3 more developer resources.
