Protostar AI, LLC · Secure AI platform
Privacy with AI.
Use the world's best models on your most sensitive data, without ever handing it over. Protostar AI anonymizes it before it leaves your walls and rebuilds the answer inside them.
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.

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.
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
HIPAA, SOC 2, IEC 62304, and MiFID II are part of the architecture, not a checkbox added 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.

Let's talk 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.
