About DataRoot Labs

We are DataRoot Labs (DRL) — a team of experts with an ambition to help Ukrainian Data Science and AI industries flourish. We’ve been creating R&D for well-funded startups from Europe, Israel, and the US since 2016.

We enjoy working on complex AI projects using state-of-the-art technologies and solutions. The harder the challenge, the funnier the project.

Our team is not only a band of enthusiasts and professionals but also a place for great individuals with a strong get-shit-done attitude. Everyone believes that most of the time, bureaucracy is what stops us from doing more. That’s why the team structure is flat — you can talk to anyone for collaboration, ideas sharing or ask for help.

Our office is in the Kyiv downtown, with a magnificent 360-view on the Ukrainian capital.

In 2017, we started DataRoot University with a goal to deliver the most comprehensive data science and machine learning courses completely for free.

We also run a Telegram channel where we share the latest research findings, technological news, and other Data Science related content: https://t.me/datarootlabs
