Behind the technology, a human story.

Our mission

What we believe

We believe in a world where every person who needs help can receive it.

AI can amplify frontline workers and public service professionals — but only if it's built for them, with them, and held to a higher bar.

It must serve the public interest, not shareholders.

That's why we chose a nonprofit, open-source model.

Open source

That's why our work is licensed under the MIT license — so public institutions and social-impact organizations really own the technology.
