Our mission
Keeping humans in control of AI.
We are building Qastel in Paris so that every team can decide how AI is used in its own work.
Why we started Qastel
Every department should be able to set the rules for how AI is used in its work.
AI is a tool. Like any tool at work, you need to know what it is used for, what data it can reach and what actions it can take. Today those answers sit with a few engineers. We started Qastel so that finance, HR, legal, sales and every other team can set them for their own work, and see them enforced.
What it is used for
The tasks AI may help with, and the ones it may not.
What data it can reach
The documents, records and systems it is allowed to see.
What actions it can take
What it may do on its own, and what needs a person first.
The founders
Engineers and product builders, in Paris.
Before Qastel, we spent our careers at Microsoft making AI and automation usable by people who do not write code.
