About DOMSELARDI
A focused team. Serious work. Software you own.
DOMSELARDI is a deep-tech software company founded in Paris in 2025. We design and operate our own infrastructure for European organisations, end to end and in-house - from evidentiary cryptography to space-grade data systems. Sovereign, and made to last.
Why we exist
Organisations deserve tools they actually control
Lock-in is the problem we solve: a lot of business software makes leaving harder the longer you use it. You deserve to stay in control of your tools and your data.
Our software gives you that freedom: you can understand what it does, retrieve your data in a standard format, and stay free to choose at any time. A good tool earns its place through value, not constraint - and trust is what keeps you.
That is why DOMSELARDI was founded in Paris: to build serious, lasting deep-tech software for European organisations - from SMEs to public institutions - and to take on the hard problems most vendors avoid: provable evidence and sovereign space-data infrastructure.
Too many organisations are trapped in tools they do not truly own - subscriptions that climb, data held hostage, migrations that never happen. DOMSELARDI was built to do the opposite: software you can understand, data you can take with you, and terms that hold over time.
What you pay for is yours: stable, guaranteed access with terms you can rely on over time.
Accessible, exportable, hosted in France. You keep autonomous access to your data, independent of our infrastructure.
A French team building software to European standards for data sovereignty, privacy and digital independence.
Our values
What we stand for, product after product
Ownership first
What you buy belongs to you: durable access, stable terms and predictable pricing you can build on with confidence.
Clarity before complexity
Good software makes sense quickly: an immediate start, with no lengthy training course or 80-page manual. Useful from day one.
Everyday reliability
A useful tool has to be there when people need it. We value continuity and stability over noise and constant updates.
Respect for your privacy
Our software runs cleanly, with no advertising cookies and no tracking tools. Your data belongs to you and stays that way - a commitment we keep.
Tools made to last
We focus every feature on what genuinely serves you. We build what works well today and will still work in five years.
Honesty in everything we do
We deliver what we announce, answer our customers directly and acknowledge our mistakes when we make them.
What we want to change
A better relationship between organisations and their software
We want European organisations to be able to choose their digital tools knowing they will truly own them - no third-party dependency, no lock-in, no data hosted on the other side of the world.
Sovereignty for every size
A ten-person SME should have the same guarantees as a large corporation when it comes to its data and its digital tools.
Software that is useful from day one
No three-month deployment project. A useful tool should be useful immediately, without intensive training or external consultants.
Durable jobs in France
Building here, improving here: that is also how we create continuity for the organisations we serve.
A price that does not change overnight
No billing surprises. What you pay today is what you will pay tomorrow.
Our commitments
Our commitments, stated plainly
Data hosted in France
Your data stays on French territory, under European law, on sovereign servers - a guarantee that holds for every one of our products.
Advertising-free by design
Our software runs cleanly, with no advertising cookies and no tracking tools. Your data belongs to you.
A stable price
What you pay today is what you will pay tomorrow: clear, predictable pricing that stays stable over time.
Software you own
What you buy is yours: stable, guaranteed access you can count on over time.
Human support
We reply to every message: a real, direct human answer, rather than a chatbot or a 200-article knowledge base.
Products that improve steadily
We improve what exists and fix what needs fixing, with steady, meaningful releases that move the product forward.
