Retain relevant context across tasks and interactions.

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.
