Programme
Themes across AI and robotics

Three themes are confirmed, two are being shaped with imec.istart and one is proposed. Each has a talk in the morning and a roundtable in the afternoon.

ConfirmedAI

AI as substitution, not augmentation

Helloprint rebuilt its core flows around agents and its organisation shrank to roughly forty percent of its size.

ConfirmedAI

Zero code, spec-driven

Altura stopped writing code in January and kept shipping to production.

AI where latency is physical

When the deploy target is a machine and three hundred milliseconds is a dropped part.

The hardware and software seam

Perception, control and firmware, and the models inside them.

The organisation after agents

Who reads the code, who is on call for a decision a model made, and what a senior engineer does.

Supply and sovereignty

Model supply that can be switched off, and what a European technical leader controls.

The night before

An optional overnight build for around fifty engineers, the evening before the festival. A short documentary of that night closes the festival day.

Talks on six themes

One talk per theme, by people who shipped it this year. No vendor decks.

Stations and introductions

Hands-on stations with the hardware and models from the build. Introductions only when both people agree.

Doors and the keynote

Doors open with coffee, then a short opening keynote.

Roundtables

Closed conversations of about ten people, one per theme.

The film and drinks

A short documentary of the night before closes the day, then drinks in the same room. Follow-up introductions are opt-in.

500 technical leaders, invited through referrals in the Builders CTO Network and imec.istart, each with a paid ticket. The mix we aim for, in percent:

The list hears the date first, gets early bird access and first choice of roundtable. One email, then nothing until the date is set.

Who is it for?

CTOs and VPs of Engineering, technical founders, staff and principal engineers, and heads of robotics, hardware and data who run systems in production.

How do I get in?

Entry is by invitation and a paid ticket. Invitations go out through referrals in the Builders CTO Network and imec.istart. Join the list to hear when tickets open.

What does a ticket include?

The full day: the six themes, a roundtable seat, the afternoon stations and introductions, the film, the keynote and closing drinks. Early bird tickets come with first choice of roundtable.

Do I have to join the build the night before?

No. It is optional and limited to about fifty people. Everyone sees the film of it at the end of the day.

What happens with my details?

No attendee list leaves the building. Your details are not used for outreach, and there is no mass mailing afterwards.

When are the date and venue announced?

As soon as they are fixed. People on the list hear first.
