The programme

How the Summer Course is structured

6 & 7 August 2026 — Dutch edition Register 20 & 21 August 2026 — English edition Register

Day 1 • Full day

Behavioural AI

Together we build a working flow: from behavioural insight to prototype intervention. You learn how to use AI inside the SUE Influence Framework. How to accelerate Jobs-to-be-Done analyses. How to generate and stress-test intervention ideas.

You go home with a working Behavioural Design AI workflow that you can use straight away.

Tom de Bruyne & Astrid Groenewegen Founders, SUE Behavioural Design

Dinner after day 1

Because the best conversations don't happen in the classroom. You eat together with the group and the founders.

Day 2 • Morning

The Happiness Code

Based on Astrid's book The Happiness Code. A behavioural designer's take on wellbeing. How do you design environments, at work, in your team, in your life, where people function better? Which small tweaks produce big differences in energy, focus and wellbeing?

Astrid Groenewegen Co-founder, author of The Happiness Code

Day 2 • Afternoon

Gamechangers

Based on Tom's book Gamechangers: How small interventions unleash big changes. The book is not yet available in English, but participants on the English edition receive an exclusive translation.

Why is change so hard? Because beneath the surface, countless system forces are at play, forces we're blind to. In this workshop you learn to see the invisible leverage points of change, and how to press on the ones that actually move things.

Tom de Bruyne Co-founder, author of Gamechangers

Follow-up after three months

A two-hour accountability session. Who is putting it into practice? What works? What's stuck? Because knowledge only becomes knowledge once you turn it into routines.

Why it works

Designed for impact

Small group, maximum exchange

With sixteen participants there is room for real interaction with Tom and Astrid, but at least as much with the people next to you. You bring your own experiences and challenges, and learn from the practical insights and questions of professionals just as motivated as yourself. That is what makes a small group so powerful.

Two founders, two days

No junior trainers, no recorded videos. Two intensive days working directly with Astrid and Tom, the founders of SUE. And just as important: meeting like-minded peers who will be a valuable addition to your network long after the training. There is plenty of room to exchange knowledge with each other during the training and the dinner.

Take your working AI flow home

No slides you'll never open again. On day 1 you build a Behavioural Design AI workflow that you use from Monday morning.

Two books included

You receive The Happiness Code by Astrid and Gamechangers by Tom (English participants get an exclusive translation, the book isn't published in English yet). The theoretical foundation for day 2, and a reference for afterwards.

Frequently asked questions

Still have questions?

Do I need prior knowledge?

No. The Summer School is designed so that both alumni and newcomers get the most out of it. Alumni deepen their work with AI acceleration. Newcomers build the foundations and the AI workflow at the same time in two days. The shared frame, human intelligence × artificial intelligence, is new to everyone.

What do I take home?

A working Behavioural Design AI workflow you can use immediately. Two books (The Happiness Code and Gamechangers, with an exclusive translation for English participants). And after three months, a follow-up session in which you learn from what everyone has put into practice.

What's the difference with the Fundamentals Course?

The Fundamentals Course teaches you the complete Behavioural Design method in two days. The Summer School is different: you combine BD with AI in a working flow (day 1), and you get two exclusive masterclasses from both founders based on their books (day 2). Plus: dinner, follow-up, and a group of sixteen.

What's included in the price?

For €1.749 excl. VAT you get: two days of training with Tom and Astrid, a group dinner on day 1, a follow-up accountability session after three months, and the books The Happiness Code and Gamechangers (English participants receive an exclusive translation of Gamechangers). No optional add-ons, no early bird gimmicks, no surprises afterwards.

Can I expense the Summer School to my employer?

Absolutely. You receive an invoice in your organisation's name. The training is professional development in behavioural design and AI applications, and qualifies for training budgets. Need a quote? Email us and we'll sort it.
