What Endstack does

Endstack is a desktop OS optimized for humans and agents running in the cloud. Your desktop is powered by endOS, giving you a real desktop workspace in the browser backed by Linux in the cloud. Files, notes, browser tabs, native apps, terminals, and all your agents in one beautiful, familiar, interface. You get a powerful agent running 24/7, integrated at the system level into endOS that you can also reach via Slack, email, or SMS. Endstack desktops are also natively multiplayer, allowing for realtime collaboration with teammates.

Cloud desktop OS for humans and agents

What is your company going to make? Please describe your product and what it does or will do.

We are building Endstack, a desktop OS that runs in the browser backed by Linux in the cloud. It combines files, notes, browser tabs, native apps, terminals, and intelligent agents into one interface. Users get a system-level AI agent always on, reachable through Slack, email, or SMS. Our OS is also multiplayer, enabling real-time collaboration within the desktop environment.

Where do you live now, and where would the company be based after YC?

We live in Los Angeles, CA, and after YC the company will remain based there.

Explain your decision regarding location.

We picked Los Angeles because that's where we live and work. It gives us the environment and resources we need without relocating, and YC can support remote founders.
