They act
Our agents do not produce suggestions for you to copy out. They open the ticket, reconcile the entries, chase the supplier, prepare the file. Every action is timestamped, traced and reversible.
For forty years,
we put people
behind screens.
Constellar gives them their time back.
The machine handles the rest.
The observation
Forty years of computerisation delivered on the promise: processing is faster, tools are more powerful, information moves better than it did. But the load changed hands — and the time spent in front of a screen has only grown.
Re-keying from one tool into another. Reconciling two tables that do not talk to each other. Chasing, filing, reporting, starting over because one document was missing. That work did not exist before screens. It now fills entire days, and it appears in no job description.
The reversal
Constellar is not trying to make people work faster in front of a screen. It takes the work off the screen.
What is repetitive, verifiable and requires no judgement goes back to the machine. What requires a decision, accountability or a relationship goes back to people — with the time it takes to do it properly.
What we build
A service that orchestrates autonomous agents, delivered as a complete and isolated installation for every client.
Our agents do not produce suggestions for you to copy out. They open the ticket, reconcile the entries, chase the supplier, prepare the file. Every action is timestamped, traced and reversible.
An agent that forgets starts over, and an agent that starts over costs more than a person. Ours keeps the state of what it undertook, resumes after a failure exactly where it stopped, and can say what it did, when and why.
One client, one installation. Your data never meets anyone else’s, trains no model, and stays hosted in France. Isolation is not a setting: it is how the product is built.
The standard
A successful demonstration proves nothing: it shows that it worked once. We require the opposite — that the failure be reproduced before the fix is accepted.
Every safeguard is tested both ways: we check that it lets through what must pass, and that it stops what must be stopped. Backups do not count; only restores we have actually replayed do.
The founder
Fifteen years industrialising other people’s IT — operators of vital importance, the accounting and regulatory chain of a corporate bank. Constellar came out of what he saw there.
