About ProjectX
Summary
ProjectX builds InfinityOS, a cloud-based operating system that runs each application in its own isolated environment with dedicated GPU and compute, letting humans and AI agents work across multiple heavy apps simultaneously. It targets B2B teams and AI agents running GPU-intensive workloads like 3D rendering, simulation, and model training, replacing the single-cursor, single-focus constraint of traditional desktop and remote-desktop setups. Any agent can orchestrate workloads through a chat interface, and the workspace runs entirely in a browser tab with no installation required.
Business model
Per-app GPU usage, with a pricing page indicating tiered plans.
Go-to-market
AI agent developers and GPU-heavy professional teams are the primary buyers, reached through self-serve sign-up directly from the browser with no installation barrier.
From the Y Combinator listing
Agent native workspace for heavy parallel workflows on the web
Every computer ever made forces you to do one thing at a time. One cursor. One keyboard. One Hardware. One app in focus. Fifty years. Nobody questioned it. We did. We started over. We built InfinityOS, a fundamentally new computer OS on the cloud from ground up. Infinity runs every app in its own independent computer -- own GPU, own input, own environment. Windows and Linux in the same session. Humans and agents working side by side. No concurrency ceiling. Cold start in seconds. runs on the browser of any device..
