What we stand for
Built around the people who use it.
Two promises shape every release: what you can count on as a customer, and the standard we hold the product to.
For the people who use it
C01
Start in seconds
No sales call and no setup. Open the product and get to work.
C02
Straight with you
We say plainly what the product can do, what it can't, and when it gets things wrong.
C03
Outcomes over output
We measure ourselves by the work you finish, not the words we generate.
C04
You stay in control
Stop, steer, or retry at any point. The product works for you, not the other way round.
In the product
P01
Product first
We ship things you can use today, not decks about what is coming.
P02
Craft in the details
Speed, clarity, and polish are features. We sweat them.
P03
Reliable by default
We test and verify before we ship, and fix fast when we miss.
P04
Open foundations
We build in the open where we can, so the whole field can stand on it.
Careers at Celestris
Come build the next horizon.
We keep the team small, the ambition large, and the work in the open. If you would rather build the instrument than read the paper, we should talk.
