HDW2026 Official Afterparty

Welcome to the Official Helsinki Data Week 2026 Afterparty!

After a long week of data & AI events and activities, what better way to spend Halloween night than sipping cocktails (or mocktails) and snacking 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 refreshment needs (but you'll need to buy your own drinks!).

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

Note: space is limited!
