Why Plenary
One room, one track, two very full days.
We keep the format simple on purpose. Every talk happens on one stage, workshops run in small rooms next door and the breaks are long enough to actually meet people.
01
Talks that go deep
Forty-minute sessions with time for real questions. No sponsored keynotes and no product pitches.
02
Workshops you can use
Hands-on sessions on research, prototyping and pricing, capped at thirty people each.
03
A hallway worth the trip
Long breaks, a shared lunch and an evening social by the river, planned for meeting people.

Why we cap the room at 1,200
A smaller room means shorter queues, better questions and more time to meet people.
