Hi! 👋

We are a Python and JS/TS software house that specializes in developing unique products and composable systems.

Founded in 2009, starting with a few people in a tiny office, but with huge ambition and dreams to do something important in the software industry, not only commercially.

We transform businesses by delivering sustainable, API-first (while not always easy to achieve, it’s worthwhile), efficient and modern solutions. We empower businesses of all sizes, from high-volume online retailers to disruptive innovators mentioned on the Forbes Next Billion Dollar Startups list. 🔥

One of the most important things at Mirumee is that our culture is centered around people and open source. We are active members of the open source community, creating Ariadne, a schema-first GraphQL server library for Python, eagerly sharing our knowledge as mentors and speakers at events across the globe and creating the biggest GraphQL Meetup in Poland and beyond.

But first of all, we care about technical excellence, open communication, and treating each other with respect as equal human beings.
