Community-organized, English-language data week in Helsinki, held late October since 2024 (idea from November 2023, name coined by Antti Rask). Not a single-venue conference: each edition is an umbrella week of events across multiple Helsinki venues. The organizers run one central 'Opening Event' (free in 2024 at Apollo Live Club; paid, two-stage, at Epicenter in 2025 and 2026), plus paid masterclasses from 2026; the rest of the week consists of free events hosted by sponsor/partner companies (e.g. Agile Data Engine's ADE Summit, Snowflake, Databricks, Nortal, AWS partners, MotherDuck) at their own venues, and an after-party. Year-round 'Low-Key Data Meetups' and partner meetups run between editions. Edition venue fields name the opening-event venue. Category is 'vendor' because most of the programme is vendor-hosted. Social accounts are the event's own.
