ProjectX is a San Francisco-based, Y Combinator-backed startup building Infinity (InfinityOS) - a cloud-native, distributed operating system where every app runs on its own independent compute and GPU inside a single browser tab. Designed for the multi-agent, GPU-native era, it lets humans and AI agents run Blender, Unreal, Isaac Sim, DaVinci, and VS Code side-by-side in one shared workspace.
Factory builds agent-native software development for enterprises. Its Droids - specialized AI agents for coding, reliability, product, and knowledge work - take tickets, write code, open PRs, and triage incidents alongside human engineers. Founded in 2023 by Matan Grinberg and Eno Reyes, the San Francisco company raised a $150M Series C in April 2026 at a $1.5B valuation led by Khosla Ventures.
