How it works

Protected before it ever leaves.

A request is anonymized on your side, split into pieces, and sent out so no single model ever sees the whole. The answer is rebuilt inside your walls.

How Protostar AI works: a secure boundary with no egress for regulated data. A caller sends a request to the Secure AI Gateway inside your boundary. The gateway classifies, anonymizes, routes and audits. Regulated data stays on the self-hosted Tier 1 with no egress; an encrypted vault holds the real values; only de-identified data may reach managed Tier 2 or fragmented Tier 3 providers. Everything is re-identified and recombined inside your boundary before the answer returns.

Regulated data (green) never leaves your boundary. Only de-identified data (violet) can reach external models, under ZDR and BAA, fragmented across providers.
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.

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.

  • Product, not slideware. We ship software people actually use.
  • AI as a default. Intelligence is built in, not bolted on.
  • Own the stack. We build and operate what we launch.
  • Durable by design. Built to last, not to flip.

Bring your most sensitive use case. We will show you how the gate protects it.
