How it works

Protected before it ever leaves.

Why Protostar AI

Capability and privacy, together.

You were taught to choose: powerful AI or private data. Protostar AI ends that choice. Privacy runs in front of the model, so the two stop competing.

Use the frontier

Run the latest Claude, Gemini, and GPT-class models on real, confidential work. The gate keeps you current without locking you to any one vendor.

Never exposed

Sensitive data is anonymized before it leaves and rebuilt inside your walls. The most sensitive data never leaves your infrastructure at all.

Built for the regulated

Designed to HIPAA, SOC 2, IEC 62304, and MiFID II controls from the start, not bolted on later. Every request is classified, logged, and audited.

The portfolio

Built and proven on our own ventures.

We build and operate real products across regulated domains: medical, financial, and more. Protecting their data is exactly why Privacy with AI exists.

Protostar Station

Deeply your AI company.

Run a whole company with AI agents, on your own computers, with your own accounts, and approve anything that leaves with a passkey.

  • Every session, one hub

    Every Claude Code session on your computers reports to the hub, started by hand or by Station.

  • Frontier models on your own accounts

    Your crew runs on the subscriptions you already pay for, logged in on your own computers. The hub never holds a vendor login or key.

  • Approve, don't babysit

    When your Delegation of Authority says an action needs you, the crew asks and waits. You approve with your passkey, on your computer or your phone.

  • A company, not a chatbot

    Org chart, tasks and missions, a Board Room, budgets, fleet and documents, with a room for each project.

About

Privacy is the architecture.

Protostar AI, LLC builds a secure AI platform that lets organizations use the best models in the world on the data they are most obligated to protect. The most sensitive data stays on self-hosted models that never touch the internet. Everything else is anonymized and rebuilt inside your walls.

A protostar is a star in the making, and that is how we think about what we are building: dense potential, gathering momentum, designed to last.
