HDW2025 Official Afterparty

Welcome to the Official Helsinki Data Week 2025 Afterparty!

After a long week of data & AI events and activities, what better than to spend the Halloween night sipping cocktails (or mocktails) and snacking on snacks at Bar Mate!

This is a low-key, chill afterparty - we want to wind down in good company and toast this year's successful event.

Bar Mate is one of the best cocktail bars in town and specializes in highball cocktails (if you don't know what those are, you'll find out!). Attendance is free, light snacks are provided, and the bar will serve your needs for refreshment (but drinks you'll need to buy for yourself!).

Join us after Friday's HDW events, starting at 17:30!

Note: space is limited!
