Applied AI, with people at the center.

We believe AI should work for people, not replace them. We build applications that help everyone reach their full potential, on their own terms.

The usual question

How much can AI do without people?

We ask

How much more can people do with AI?

Every AI solution should start with a person and leave that person better off: healthier, more capable and more secure.

Our focus

Four areas guide everything we build.

Leverage

Amplifying what people can achieve together, so the impossible becomes solvable.

Thriving

Technology that helps people feel better, live better and do more.

Protection

Security and privacy that shield people from other intelligence.

Discovery

Helping people and science solve problems never solved before.

How we work

Others build models. We build what people use.

We work at the application layer, where AI meets everyday life. We choose the best model for each problem and design the experience around the person.

Model-agnostic

The right model for the job, on device or in the cloud.

Private by design

People's data serves people, never the other way round.

Built to ship

Decades of taking products from the lab to millions of people.

Chronotype home screen: your day, perfectly timed, with AI coaching tuned to your circadian rhythm. Chronotype rhythm screen: a circadian score built from sleep, activity and consistency. Chronotype voice coach: a real-time health coach that knows your data.
Our first project

Chronotype

AI coaching built around your own biology, so you can work with your body's rhythm instead of against it.

Build with us.

We're engineers, designers and scientists who have shipped products to millions. If you're an app developer, an enterprise, a government agency or a nonprofit and this direction excites you, we'd like to hear from you.
