Official After party

Welcome to the Official Helsinki Data Week 2026 After Party!

After a long week of data & AI events and activities, what better way to spend Halloween night than with good company.

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

The venue is yet to be determined, we’ll let you know as soon as we have it locked.

Attendance is free. Once we have the venue, we’ll add an event on Meetup.com where you can register.
