We help our clients bring their product vision from zero to one
Who we are
Founded in 2016 in Warsaw, Poland, we began as a small group of six dedicated professionals. Today, we’ve grown to a team of over 70 experts, all focused on creating applications that drive change.
What sets us apart? Our deep technical expertise combined with a strong business perspective. For nearly a decade, this has enabled us to support clients across Europe, the US, and Australia, helping startups and enterprise-level organizations deliver impactful solutions. Our broad expertise in various industries like banking, fintech, well-being, FMCG, healthcare, and sports equips us to confidently approach and resolve the complex challenges that organizations face today.
We build our frameworks (i.e., Patrol) and solutions, contribute to open-source projects, offer a custom Internship Program, and give lectures at several universities in Warsaw, Poland. We are also an official Flutter consultancy firm.
