How a 90-minute session turned AI curiosity into a builder mindset
In this edition of our AI in Action series, we speak with Kilian Drewel, Product Marketeer at team.blue's Infrastructure unit, about how he co-hosted a vibe coding session that got 16 people from different backgrounds to build working AI prototypes in 90 minutes. What started as an experiment in hands-on learning is now scaling to 230+ AI Champions across team.blue.
AI across team.blue
At team.blue, AI shapes how we work, how we build, and how we serve millions of European SMBs every day. It's embedded across our ecosystem, delivering smarter experiences and simpler paths to success. The strongest proof comes from the people who carry that forward.
What Kilian did
Kilian Drewel, Product Marketeer in team.blue's IaaS / VPS and Managed Hosting unit, co-hosted a vibe coding session together with team.blue CTO Danielle Kroes. A vibe coding session is a hands-on format where people from different teams use AI tools to build working prototypes from scratch. Just 90 minutes of building, together.
16 people joined, split into 4 teams of 4. Each team picked their own theme: onboarding, customer experience, infrastructure automation, or analytics and insights. And started creating.
Why he did it
AI is in team.blue's DNA. The AI Champions program is a group of volunteers who drive hands-on adoption across the organisation by running events, sharing use cases, and bringing AI knowledge directly into their local teams. It is people choosing to lead from where they stand.
As an AI Champion, Kilian saw a gap he wanted to close.
"Most AI learning still happens in Zoom calls, demos, or individual experiments. You understand the basics, but you don't always get to apply them."
People across team.blue were curious about AI, many already experimenting on their own. The missing piece was a space where learning could happen collectively, with real tools and a clear goal: ship something in 90 minutes.
The tools they used
Teams chose their own stack: BlueChat (team.blue's internal AI platform), team.blue brand Macaly (a no-code AI web app builder), or anything else they preferred.
To reduce friction and help everyone move quickly, Kilian prepared a set of practical tools inside BlueChat: the Lazy Prompt Enhancer, which turns rough prompts into more structured, higher-quality ones; the Macaly Prompt Builder, which helps people think through what they want to create before they start; and a frontend design skill that generates clean, modern web designs directly inside BlueChat.
Simple, practical, designed to get people building within minutes.
What they shipped
Every team delivered a working prototype within 90 minutes.
The results included an onboarding tool to help new engineers navigate internal infrastructure, a price comparison tool to evaluate options faster, and a ticket-routing tool that sends support requests to the right team automatically.
None of it was polished, and that was the point. These were early versions, good enough to prove what's possible and give teams something real to build on.
"It was exciting to see what people can ship in such a limited timeframe. It was even more exciting seeing people adopt a builder mindset."
The energy after
Kilian was happy to see that once the 90-minute session was over, the team kept experimenting, refining their ideas, and sharing what they had built with colleagues.
"What stood out most was what happened after the session ended. People kept experimenting, refining ideas, and sharing what they built. That kind of momentum is hard to create in a typical learning setup."
That energy is now being channeled further. The vibe coding sessions are being extended to the rest of team.blue, starting with the 300+ AI Champions across the organisation.
Kilian himself keeps building. He recently created an agentic Slackbot connected to Confluence, a tool for internal knowledge sharing, that answers questions about team.blue's cloud products. Now he's working on a content workflow that takes a product from brief to CMS-ready.
"Generative AI is the biggest technological shift in years. At team.blue, we're a collective of thousands of entrepreneurs and digital natives, and that energy is contagious. You can literally just build stuff."
Part of a bigger picture
What Kilian and Danielle started with 16 people in a room is already spreading. That's how AI scales in an organisation of 4,000+ people across 22 countries. When people build together, AI stops being a concept and becomes a culture.
