Finding after-school activities for a kid in Poland usually means three open browser tabs, a parents' group chat, and a Facebook post from 2022. GrowKido is the platform I co-founded to fix exactly that: one place where parents find and book children's classes near them.

Search by where you actually are

GrowKido is map-first. You see what's genuinely close — in Warszawa, Kraków, Wrocław, Poznań, Gdańsk, Łódź, Szczecin and smaller towns alike — and filter by the child's age and the kind of activity: sport, languages, music, dance, art and tutoring. No more guessing whether "near the centre" means a 40-minute tram ride.

Built for both sides

For parents it's free and direct — you contact the instructor or school yourself, no middleman taking a cut of the conversation. For providers, listings are free too: a swimming school in Gdańsk or a coding club in Kraków gets found by the families actually looking, instead of paying to shout into an ad auction.

Why a two-sided map is the hard part

The interesting engineering is making "what's near me, for a 7-year-old, on weekday afternoons" fast and obvious across a whole country's worth of listings. That's geo search, sane filtering, and a map that doesn't melt your phone — the unglamorous work that makes the simple thing feel simple.

If you're a parent in Poland, try GrowKido. If you run classes for kids, list them — it's free, and the right families are already looking.
