Build with AI. Move the whole team forward.
Twenty years ago, every team had an expert who built the Excel file everyone relied on. Today, that person builds the prototypes, automations and agents that move their colleagues forward — with AI.
The tracks made for those who make the difference. To go further, together.

Create and automate with AI, for the whole team
One in three Belgian workers already uses generative AI. How many have been trained? 14%. The rest learn on their own, by trial and error.
The AI Builders tracks take the opposite path: tools that run, measurable results, and methods to bring back to the whole team the very next day. No code on stage. No magic either — method.
You prototype? You automate? You're in the right place.
For more than ten years, DevDay has brought together the people who make software. Today, people build tools with AI in every profession — that's why the AI Builders tracks exist. What qualifies you isn't your job title. It's what you build.
What about the programme?
The first names are coming in and the event is in December: the rest will be revealed by October. What you can check today — ten editions, 40 talks, 7 rooms. What won't change: tools that run and measurable results, not promises.
What about my day?
Two dedicated tracks, Create and Automate, and you move freely between them. The rest of the event stays open if a technical topic catches your interest.
What about the level?
No code on stage. We assume you know what you want to build, not that you know how to program it. Sessions show methods and tools, and go deep rather than skimming the surface.
You build the tools your team needs
Product owner, analyst, designer, project manager, consultant: you describe tools all year long. With AI, you can show them. A clickable prototype instead of a spec to interpret, a running workflow instead of a diagram to imagine.
In meetings, you no longer debate what the tool could do: you look at what it does. And your devs start from a concrete base to build the real version.
Taking the stage
Applied AI experts and builders coming to share what they're passionate about. First announcement below, the rest will be revealed by October.
Your AI Builder ticket
A full day across two dedicated tracks: Create, to go from idea to tool, and Automate, to go from repetitive tasks to agents. You move freely between the two. Between talks, the encounters that matter — with other builders, and with the developers who will take over your prototypes.
AI Builders
Master modern techniques — vibe coding, no-code, AI — to unlock your potential and increase your impact at work.

Proposals are submitted via the form on this page, in the Call for Papers section. Describe your topic and preferred format. You can also use this link directly: https://sessionize.com/devday-2026/
DevDay 2026 takes place at the Palais des Congrès de Mons, Belgium, on 3 December 2026. Mons is reachable by train in 50 minutes from Brussels, 1h20 from Liège and 1h30 from Paris.
Several partnership formats are available: brand visibility, on-site presence to meet the Belgian tech community, recruitment opportunities. Contact Deborah Bourgeois (deborah@devday.be) to receive the 2026 partnership brochure.
DevDay offers three types of tickets, designed for its three audiences: Developers, AI Builders and Executives. Each type gives access to a dedicated track, with content tailored to each profile and its level of technicality.
No, DevDay aims to bring together everyone in tech who contributes to software development. The audience is mostly developers, but also AI Builders and business leaders. The programme is designed to offer relevant content to all three profiles, at varying levels of technicality.
No. DevDay is open to all profiles, whether it's your first talk or your tenth. What matters is the value of what you have to share. Speakers are chosen by a selection committee that assesses sessions on their relevance and fit within the programme.
Absolutely! DevDay is the ideal place to meet and talk with other developers, AI Builders and leaders of the tech scene. Dedicated moments throughout the day give you time to network: breaks, lunch and the afterwork at the end of the event.
Yes. An invoice in your company's name is issued for each ticket. For a purchase order or a specific procurement procedure, contact contact@devday.be.
DevDay is mainly held in French, reflecting its roots in Wallonia. Some sessions may be given in English depending on the invited speakers.
DevDay is looking for concrete first-hand experience: a difficult technical decision, a system put to the test, an architecture that evolved under constraint. DevDay is committed to putting both international and local experts on stage. We also make sure the diversity of the profession is represented. Vendor proposals and purely promotional talks are not accepted.
Yes, the Palais des Congrès de Mons is fully accessible to people with reduced mobility. For any specific needs, contact contact@devday.be.
Yes, and it's even strongly encouraged: coming as a team multiplies what everyone gets out of it. A group rate is available to all teams of 5 people or more. And for companies that want to offer more to their teams, we can design a tailor-made premium experience (dedicated welcome, reserved seats, branded goodies and t-shirts…) — write to us at contact@devday.be to discuss a premium package.
Yes, tickets are personal but transferable up to 7 days before the event by contacting contact@devday.be with the details of the replacement attendee.
DevDay is an in-person experience: sessions are not recorded for replay. That's what makes the encounters, the conversations and the energy of the day unique.
A reduced rate is available for students, in collaboration with DevDay's partner schools and universities. If you're a student and interested, contact your institution's management to find out whether participation is planned — and feel free to put us in touch with your school (contact@devday.be) if needed.
