Speakers are being confirmed week by week. The full grid of speakers and sessions will be available in November. Book now to be there when they take the stage.
Leave with
gold.
The whole Belgian tech community
1000+ developers, AI builders and tech leaders in one place. Conversations that carry on after the event. A network built on shared experience, not on business cards swapped in a hurry.
Skills you can apply the very next day
No sleight of hand: every session is first-hand field experience. The goal isn't just to inspire you, it's to equip you. You leave with concrete patterns, proven tools and techniques your team can adopt right away.
Talks that don't pretend
DevDay selects speakers who talk about what they've built, not what they're selling. Every talk is real experience: what worked, what broke, and the decisions that changed everything. No generic slides. No perfect demo.
A head start on AI in production
AI is more than an impressive demo. Here, we talk about what really holds up in production: architectures that scale, guardrails, real costs and lessons learned by those who have already shipped it. You leave with a clear view of what works and what doesn't work yet.
One day, not a week
A single day, 3 December in Mons. Dense, focused, no filler. For teams and freelancers alike, no need to block a week in your calendar or cross Europe.

Coming as a team?
Your team deserves better than the back row. For companies that want to make it count, we design a tailor-made premium experience: dedicated welcome, a lunch table, front rows, DevDay-branded goodies and t-shirts. Profiles can be mixed to fit your team. Let's talk.
DevDay 2026 ticketing is open. Take advantage of the Super Early Bird and Early Bird rates until 15 September 2026. After that, the full price applies. Book your seat now.

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.
