Private foundation models

Your business deserves its own foundation model.

We take regulated, data-rich enterprises from raw proprietary data to a deployed, private foundation model — trained on GPU hardware we own, inside a security boundary we control. Your model. Your weights. Your walls.

The problem

Off-the-shelf AI was never built for your business.

Public models don't know your data, your domain language, or how your business actually works — and the gap shows exactly when the stakes get real.

Generic by design

Public LLMs are trained on the open internet, not your domain. They guess at your terminology, your workflows, and your edge cases.

Privacy is a dealbreaker

Regulated teams in healthcare, finance, and the public sector can't ship sensitive data to closed third-party APIs — full stop.

Building in-house is brutal

A from-scratch model means scarce ML researchers, GPU clusters, and seven-figure budgets before you see a single result.

So you rent, never own

Leasing someone else's model means no control over the weights, the cost curve, or the roadmap. Prices and terms change under you.

What you get

A full-stack foundry for private foundation models.

One accountable team owns the entire stack — from your raw data to a model running in production, and keeps improving it.

01

The model is yours

Private weights, delivered. Your data never leaves your boundary, and you get full control of cost, latency, and roadmap — forever.

02

Trained on hardware we own

Your model trains on our dedicated DGX H100 fleet — owned, not rented from a cloud. Not shared, not exposed, inside a boundary we control.

03

A platform, not a project

Reusable model-building technology — data pipelines, training stack, evaluation tooling — that gets better with every model we ship.

How it works

Raw data to deployed model — one accountable team.

Data foundation

Securely ingest, clean, and structure your proprietary data.

Architecture

Select or design the model architecture for your use case.

Train

Train on dedicated GPUs using our efficiency stack.

Align & evaluate

Domain evals, safety, and human feedback.

Deploy & operate

Private deployment, monitoring, continuous improvement.

Track record

A custom model is a bet on the team. Here's ours.

You can't benchmark a model that hasn't been built yet — you can only judge the people who'll build it. Two proof points: one for research firepower, one for shipping in the hardest regulated environments.

Research firepower · PieBot

International-Master chess on ~$5 of compute

Our team trained an AlphaZero-class engine to International-Master strength in 12 hours on a single consumer GPU — about 600× cheaper than the original run. A chess engine isn't a foundation model, and we won't pretend it is. It's a measure of the team you're hiring: engineers who get frontier-grade results out of modest hardware — the same discipline that keeps your training bill sane.

Shipping power · Clinical AI

Private foundation models, live in regulated healthcare

The other half of the job is production. We deployed a local-first foundation model in behavioral telehealth — on-device inference with ML-derived PHQ-9 depression scoring from audio. Private by default, serving real patients, inside a HIPAA boundary.

Industries

Built for teams where privacy isn't optional.

We work with data-rich organizations in regulated verticals — where a private, domain-tuned model isn't a luxury, it's the only way to ship AI at all.

Healthcare

Clinical models that keep PHI inside your HIPAA boundary — proven in production.

Behavioral health

Sensitive conversations, on-device inference, measurable outcomes.

Financial services

Auditable models you can stand behind in model-risk review — tuned to your book and your risk language.

Legal

Privilege stays intact — documents never leave your boundary. The model comes to the data.

Public sector

Sovereign, auditable AI on dedicated hardware — not a shared cloud.

Infrastructure & security

Your model trains on machines we own — not a shared cloud.

We put our own capital into a dedicated NVIDIA DGX H100 fleet so customer models never have to touch rented, multi-tenant infrastructure.

  • Single-tenant training. Your model trains on dedicated systems inside a security boundary we control — hardware-level isolation, not a slice of someone's cloud.
  • Your data is never used to train anyone else's model. It exists in our environment for one purpose: building yours.
  • Deployment on your terms. On-premises, in your VPC, air-gapped, or fully on-device — we've shipped local-first models in regulated healthcare where data never leaves the device.
  • No ongoing dependency. You leave with the weights and everything needed to run them. Staying with us for operations is a choice, not a lock-in.
  • Auditable end to end. One team owns data handling, training, and deployment — so when compliance asks how the model was built, there's one accountable answer.

FAQ

Questions customers ask us.

Do we really own the model?

Yes. You receive the trained weights and full rights to run them wherever you choose — your datacenter, your cloud tenancy, or on-device. There is no ongoing dependency on us to keep using your model.

Where does our data go during training?

Training runs on GPU systems we own outright, inside a security boundary we control — not a shared public cloud. Your data is used only to build your model, and deployment options include fully on-premise and on-device setups where data never leaves your environment.

How is this different from fine-tuning a big API model?

Fine-tuning a closed model still leaves someone else holding the weights, the pricing, and the roadmap. We build you a foundation model shaped around your domain from the start — one you own, can audit, and can run at a cost structure you control.

Isn't a custom foundation model prohibitively expensive?

It used to be. Training efficiency is this team's founding obsession — in public research, we reproduced an AlphaZero-class result at roughly 600× lower cost than the original. We bring that same discipline, plus GPU hardware we own outright, to every engagement — so a focused, domain-specific model costs a fraction of the 2020-era playbook.

How long does an engagement take?

A typical path starts with a scoped paid pilot to prove value on your data, then moves to a production build. Because one team owns every step — data, architecture, training, evaluation, deployment — there are no hand-off delays between vendors.

What happens after the model ships?

Models aren't static. We monitor, evaluate, and retrain as your data and needs evolve — on the same dedicated infrastructure your model was born on. You can run it yourself, or keep us accountable for it in production.
