Our values

Get the fundamentals right

The biggest wins come from foundational advancements and long-term thinking. We solve problems at the root, articulate the tradeoffs from shortcuts, and invest in infrastructure and process. Progress in AI models is fundamental to progress in AI.

Build to solve problems

We're accountable not just for how well we do our work, but for whether we're working on the right problems in the first place. We actively seek out the biggest bottlenecks and solve them. We build with our users in mind, and we work to understand our users and the reality they inhabit.

Aim beyond what's possible

We find it energizing to push beyond what the world thinks is possible. We aim to be the best in the world in everything we do. We continually iterate because we can always be better.

Be honest, with ourselves and others

We admit what we don't know, and we actively question our assumptions to try to do things better. We're always curious about how we can improve, and we're curious rather than defensive when we disagree. We're honest with others and say what we mean plainly and directly.

Have fun with it

We take the work seriously, but not ourselves.

Frequently asked questions

Does Cartesia sponsor visas?

We provide visa sponsorship support and assess each circumstance on a case-by-case basis. However, visa sponsorship is dependent on many factors, including the role you are applying for and the location you are going to be based in, so we can't always guarantee success. Your recruiter will work with you to understand your visa sponsorship needs from the first call.

Does Cartesia work in person?

We're an in-person team based out of offices in San Francisco, London, and Bangalore. We love being in the office, hanging out together, and learning from each other every day.
