The European AI platform built for serious work.
High-quality language models, an OpenAI-compatible API, and EU-sovereign infrastructure. One platform for teams and developers who need real performance without shipping data across the Atlantic.
European teams are stuck with bad tradeoffs.
Today's AI market forces a choice between quality, control, and price. You rarely get more than one.
Cheap but limited
Shared cloud chatbots are affordable, but your prompts and data still travel through someone else's stack — usually outside the EU. No real isolation, no serious control.
Expensive and underpowered
Dedicated "LLM-in-a-box" setups cost a fortune and ship with laptop-grade models. Hardware constraints cap the model quality, no matter how much you spend.
Sovereignty theatre
Most "European AI" providers host in their own datacenter — meaning your data still leaves your network, just with a Dutch or German flag on the invoice.
A category upgrade — not another wrapper.
Purple Donut pools high-end GPUs behind shared inference so every customer gets access to genuinely capable models, at a price that actually works. Hosted on renewable-powered European infrastructure, wrapped in an API your developers already know.
You can't ship serious AI on cheap dedicated hardware. But with shared inference done right, you can deliver it affordably — without giving up sovereignty.
From API key to team-wide AI in an afternoon.
No procurement marathon. No dedicated hardware. Just credentials, calls, and compliance that holds up to scrutiny.
Connect
Generate an API key or invite your team to the workspace. Full EU residency is on by default.
Build or chat
Use our OpenAI-compatible endpoints in code, or open the workspace for writing, analysis, and research.
Scale across teams
Workspaces, roles, usage limits, and per-team billing. Give legal a seat, give engineering full throttle.
Stay compliant
Audit logs, data processing agreements, and EU-only routing — ready for regulated industries from day one.
The tooling you expect. Where it belongs.
Everything you'd build on top of a frontier lab — engineered from the ground up on European infrastructure.
High-quality LLMs
Not compressed laptop models. Capable, multimodal systems benchmarked for real enterprise workloads — writing, reasoning, code, retrieval.
OpenAI-compatible API
Drop-in replacement for your existing SDK calls. Change the base URL, keep your code. Streaming, tools, and structured output included.
Sovereign EU hosting
Inference, storage, logs — all in European datacenters. Your prompts never cross a border you didn't choose.
Team workspaces
Chat, prompt libraries, and shared context per team. Role-based access, SSO, and per-seat or per-token billing.
Privacy-first architecture
No training on your data. Ever. Configurable retention windows, opt-out logging, and encrypted-at-rest by default.
Shared inference advantage
Pooled GPU capacity means you get frontier-class models without frontier-class bills. Throughput scales with demand, not with your wallet.
Best of both worlds. Without the usual tradeoffs.
Most vendors force you to choose one axis. We rebuilt the stack so you don't have to.

Built for regulated industries — not bolted on.
Finance, legal, healthcare, and government teams evaluate us on the first call. Here's why they keep going.
Compliant by design
DPA, sub-processor list, and SCC-free operations. No transatlantic transfer paperwork.
Data stays in Europe
Primary regions in the Netherlands and Germany. Full residency pinning available.
Financial & legal fit
Audit trails, role-based access, SSO, and configurable retention for DNB, AFM, and bar-regulated workflows.
Your data, your data
We don't train on customer inputs. Period. Opt-in telemetry and encrypted-at-rest storage.
Priced like shared infrastructure. Powered like frontier labs.
Because inference is pooled, you get serious models at honest prices. No six-figure commitments, no per-seat games — and no surprises when usage grows.
Be first in the queue.
