Sovereign platforms, built on open source, engineered to be yours
We build the platforms European enterprises run their software and their AI on: cloud native, sovereign by architecture, open source throughout, and operable by your own team from day one.
The Integrated Stack
We build the whole stack, because in practice it is one problem.
1
Sovereign cloud is the substrate
Where your workloads run, under whose jurisdiction, with what exit path. Every decision above this layer inherits its constraints, which is why sovereignty decided late is so expensive.
2
Open source is the trust layer
Not an ideology, a control mechanism. Software you can inspect, run anywhere, and leave. It is what makes a sovereignty claim verifiable instead of contractual, and it runs vertically through every layer rather than sitting in one of them.
3
Platform engineering is the method
The layer that turns infrastructure into something your developers can actually self-serve. Golden paths, automated provisioning, guardrails that enforce rather than advise. Without it, a sovereign migration produces a compliant environment nobody can ship into.
4
AI is the workload that makes all of it urgent
AI systems are the first workloads where data residency, model jurisdiction, auditability, and regulatory classification are all binding at once. Organizations that built the layers below can deploy AI. Organizations that did not are stuck at the pilot.
You can engage us on any one of these. Most clients start with one and find the next.
What we do
Our competencies
Platform Engineering and Internal Developer Platforms
We build internal developer platforms that developers actually use: self-service provisioning, golden paths, and guardrails, on open source, operable by your team.
Open Source Engineering and Support
We develop, maintain, and support the open source your platform runs on, as contributors and maintainers rather than as a support desk.
Sovereign Cloud
We assess your sovereignty position and migrate you to European cloud infrastructure, with the compliance evidence and the exit path documented.
Sovereign AI Platforms
We build AI platforms that run where your data lives: model serving, retrieval, guardrails, and audit trails, positioned for the EU AI Act from the start.
Why Liquid Reply
Why work with us
Engineering-led, not slideware
We maintain the open source we deploy. The people who write your architecture document are the people who write the code, and they are the same people you meet in the first meeting.
Sovereign by architecture, not by press release
Sovereignty claims are only worth what the architecture behind them can prove. We work to the objectives European procurement actually scores against, we document the exit path for every component we deploy, and we tell you when a workload does not need to move.
The whole stack
From the landing zone to the golden path to the AI gateway. One team, one architecture, one accountable partner.
Open source, so you can leave
Every platform we build runs on open source and standard tooling, in your repositories, in your infrastructure. There is nothing proprietary to unwind, which is the only version of “no lock-in” that means anything.
European, and part of the ecosystem that shapes this
We hold governance and advisory roles in the foundations that steward cloud native and European digital infrastructure, including the Cloud Native Computing Foundation, Linux Foundation Europe, and NeoNephos.
Packaged offers
Start with a defined step
Not every engagement needs to start with a programme. Our packaged offers are fixed in scope, price, and duration, so you can start with a decision rather than a commitment.
3 weeks
Find out in three weeks what your developer platform actually costs you, where it is failing your engineers, and what to fix first.
4 weeks
Four weeks to a clear, evidence-based answer: which of your workloads meet European sovereignty requirements, which do not, what it would cost to move them, and how fast you could exit if you had to.
6 weeks
Six weeks to a single, governed, observable entry point for every AI model your organization uses, with routing, policy, cost control, and an audit trail.
Where are you starting from?
Most conversations start with a specific problem: a platform initiative that has stalled, a sovereignty requirement in a tender, an AI pilot that cannot get past compliance. Tell us yours and we will tell you honestly whether we are the right people for it.
