From no-code to AI code: the new build era
An open, audience-driven conversation about the future of no-code in the age of AI. We’d like to connect the no-code ecosystem with how people are actually building today: what’s changing, what still works, and what teams need.

Workshop EuroStack: "how to" shift demand: bundled offers, priorities, building the business case, joint procurement
Organized around a series of questions “how do we build the bundles demand needs”, “what’s in scope”, “the business case”, “joint procurement”, everyone can participate but we will create smaller panels to discuss each topic.

Your company doesn’t need another AI tool. It needs an operating system
Adding AI to individual tasks does not automatically make a company work better. Without shared context, clear ownership, and connected workflows, teams can end up with more tools and more coordination overhead. An AI operating system is a structured way of running a business where people and AI agents work together across connected processes. In this session, we’ll cover: - The essential layers of an AI operating system: shared context, tools and connectors, safety controls and the AI operating layer. - How people and AI agents work together, with clear ownership, approvals, and escalation paths. - How to start with one useful workflow and expand without unnecessary complexity. Attendees will leave with a blueprint for connecting their scattered AI automations into a coherent operating model.

Closing the loop: building a shared memory for your organisation's AI
How can several AI tools share what they learn? This talk covers a read, act, write-back loop: agents read organisational rules, prompts and lessons before a task and record new lessons after it. Topics: scoping by team and project, ownership, review, stale entries and limits.

Alexandre Gerlic VP of Engineering
You have AI. Why are your teams still copy-pasting and switching apps?
Most teams already have AI. Yet the work still stalls, because email, spreadsheets, documents and AI assistants don’t share context, and employees end up copy-pasting between them: they become the integration layer. We will share what happens when one suite connects every tool and gives access to all your company knowledge, from calendar and email to documents, financial and CRM tools, through MCP or plugins. Superhuman does this around everyday operational work, reducing manual handoffs and helping teams act without constantly switching apps.

Beyond vibe coding: how non-developers build business apps that last
Giving business teams AI tools is easy. Helping them build applications that can be deployed, used, and maintained is harder. On Friday afternoon, Sophie described an app to an AI. Three weeks later, forty colleagues relied on it. On Tuesday morning, IT shut it down. Nobody got hacked and nobody did anything wrong. The same story could play out in any company where business teams can now build their own tools. Why AI-built business apps fail, and how non-developers can build ones that last On Friday afternoon, Sophie described an app to an AI. Three weeks later, forty colleagues relied on it. On Tuesday morning, IT shut it down. Nobody got hacked and nobody did anything wrong. The same story could play out in any company where business teams can now build their own tools. Through Sophie's story, told twice, Adrien Maret shows why generating code has become the easy part, and what non-developers and IT teams need to build apps that remain operational a year later, without slowing anyone down or putting the company at risk.

From law to code: where to put the human in the loop
How do you build trust in an LLM-based system when its users are responsible for getting compliance right? At PayFit, we have been iterating over the last two years on a “from law to code” workflow with compliance experts: identifying relevant legal changes, extracting payroll parameters, and translating legal requirements into rules. Our main lesson has been to start with what matters to the business and the experts doing the work: which mistakes have consequences, what they need to verify, and where their judgment is essential. Those priorities shape what we automate, what tool we build, how humans stay involved, and how we evaluate the results. Through concrete examples, I’ll share how we involved compliance experts at the right points in the workflow: deciding what needs their attention, what they need to review, and where they should steer the system. We’ll explore what worked, where we need to iterate, and how these choices helped build trust in the outputs.

From shop floor to dashboard: how a bakery chain builds its own software with AI
BO&MIE, the creative bakery brand founded in 2017, runs more than 25 shops in Paris, Aix-en-Provence, Bordeaux, Barcelona, Jeddah, Seoul, Riyadh and Kuwait City. Rather than buying software, CEO Jean-François Bandetchose to build the company's tools in-house with AI: an ERP for stock, purchasing and sales, and a Marketing Studio that runs Google listings, customer reviews, advertising, product visuals and local SEO. Both are built and used every day with AI agents such as Claude Code and Codex, without a dedicated developer team. Jeff shares what he has learned in the field about how AI concretely changes the way a physical retail business is run and grown.
5 unhinged AI demos, and how I built them
What happens when you take the latest AI models and try a few questionable app ideas? In this talk, I’ll show you five demos I built to explore what’s possible, including real-time voice and decision models. We’ll try them out, look at what makes each one work, and take a peek at how I built them with Lovable. Expect plenty of demos, a few prompts, and ideas you might want to steal. You don’t need a technical background to follow along. The goal is to send you home thinking, “I could build something like that,” with a better sense of where to start

Five boring practices: What 25 years of public-sector software taught us about security
You can build it in an afternoon. Now keep it running for a decade, and explain one of its decisions to a court. After 25 years building software for municipalities and government agencies, Frode shares five practices that hold up in a public-sector security review: access control as the floor, no secrets in generated code, audit records written before features, rules a caseworker can read, and an off switch the customer controls. Plus four things we got wrong along the way

What broke when I left the vibe-coding platform
I've built two AI products, LaunchDocs and Query Trenches, one without writing the code myself. I'm a former healthcare professional turned application security trainer, working a full-time job, with an AI coding platform as my entire engineering team. It worked, until I needed to own what I had built. When I exported the code and audited it, most of what looked finished on screen wasn’t. Features half-wired, no scheduler, no way to delete user data, and AI calls quietly running through US servers despite my EU-first promise. This fireside chat is the honest account of moving out. It covers rebuilding on my stack with Claude Code, switching to Mistral to keep AI processing in Europe, deciding what to rebuild versus keep, and what I would do differently on day one. This is for anyone shipping with AI tools who wants to know what’s really under the hood before their customers find out.

Inside a podcast automation stack, and how to industrialise it
Bruno Soulez has been coding since he was 12 and has spent the last seven years creating content, as creator and host of the If This Then Dev podcast. In this session he opens up the automation environment he has built around the podcast, and shows how he is now industrialising those automations with Hey Regis.
