ProjectX builds Infinity, described as the first operating system where humans and AI agents work together with no limits. It is a cloud-based OS in which each application runs on independent compute resources with dedicated GPUs within a shared workspace accessible via the browser. The platform aims to let users and agents run any application collaboratively without local hardware constraints. The company is based in San Francisco and is part of YC's Spring 2026 batch.
