Transform the way modern teams build APIs

Building APIs across teams is still messy, slow, and hard to manage. We are fixing that. With Cosmo, we are building a platform that helps teams collaborate on APIs at scale. We build in the open because we believe open source is how you earn trust and become the standard.

Join us and help redefine how teams build APIs.

Why Wundernauts love it here.

Core beliefs

The way we work together.

We work on hard problems, and we expect a lot from each other. This is how we operate day to day. It shapes how we hire, how we work together, and how we make decisions.

If this sounds like the kind of environment you want, you will do your best work here.

    Open Source Your Knowledge

    Low ego, high ownership

    Wear any hat that needs wearing. Take genuine responsibility for outcomes.

  5. 05

    We genuinely care

    No politics, no BS. We move as one team. We collaborate, have each other's backs and care about the people as much as the product and customers.

    Change is a constant, we adapt quickly. We demand a lot, yet we provide flexibility and above market pay.

    Fully remote, globally distributed

    Meaningful work can be done from anywhere. We're a fully remote company, no office, no HQ. What matters are the results.

    Work Hard, Sing Hard
