About us

Meet the mole.

A small Czech tech company building useful tools for people across Europe.

Our Story

Krte-ch is a small, independent tech company based in the Czech Republic. The name comes from "krtek" — the Czech word for mole, and the beloved cartoon character that every Czech kid grows up with.

We started because we needed tools that actually worked for life in Europe — currency conversion with real ECB rates. So we built them ourselves.

What We Believe

Software should be useful, fast, and respectful of your privacy. No dark patterns, no unnecessary sign-ups, no selling your data. Just sharp tools that do what they promise.
