About this event

🚀 Product Build Day // Copenhagen
Design capital, meet the build.

Apply here: productbuildday.com/copenhagen-september-2026

One evening. You build a working app with AI, then test it and pitch it. No code. A three-hour build night for product people who do not code. You describe what you want, Lovable builds it, and the whole room works on one shared challenge for a good cause. Free, in person, in English.

🗓️ Tuesday, 15 September 2026, 18:00 to 21:00, networking after
📍 Venue TBA, Copenhagen
🎟️ Free, by application, up to 16 seats

Sponsored by Lovable.

🛠️ Build with Lovable
Nothing to buy, nothing to install. You build in Lovable and test with AI users in Uxia. Plain English in, working app out.

🎯 One challenge, revealed on the night
No tracks to pick. Everyone builds against the same brief, set for a good cause, and you see it when the doors open. Your own roadmap idea is not for tonight. That one belongs at Pro.

👥 Who it's for
Product people in Copenhagen and the wider tech scene who want to build, not just talk about it:

  • Product managers and product owners
  • Product designers and UX
  • Marketing, sales and customer support
  • Founders and subject experts

No technical background needed. The application takes two minutes.

🎁 What you leave with

  • A working app you built yourself
  • New vibe-coding skills, learned hands on
  • A diploma, and a shot at a feature on our LinkedIn
  • An evening of mentoring and a real Copenhagen network
  • Something built for a good cause, not a throwaway demo

⏱️ How the evening runs

  • 18:00 doors, food, the brief revealed
  • 18:20 design the test, the cheapest way to prove the idea before you build
  • 18:35 build, 70 minutes in Lovable, the AI does the typing
  • 19:45 AI users test it in Uxia, findings not flattery
  • 20:30 pitches, 3 minutes each, live app, no slides
  • 20:50 a winner, and recognition for the room
  • After 21:00 networking

"I was completely immersed in the process, and I didn't even expect that I'd be able to complete the task."
