This is for you if…

You are a developer

You already use Claude Code, Codex, Cursor or similar, but you have a feeling you only use a fraction of it.

You build yourself

You are a product developer, designer or founder and want the agents to deliver something that holds up in production.

You want to see it done

You want to see how one of the best actually works, instead of reading about it.

The models are the same for everyone. Three things set the results apart, and they can be learned.

The setup

Instruction files, skills, MCP servers, tests that run by themselves. What the agent knows before you write the first prompt decides the quality of everything after.

The workflow

The task described before the code is written. A loop where the agent tests its own work, so you can leave the screen for half an hour and come back to something that works.

The judgement

What you hold on to yourself when execution has become cheap: the visual, the critical eye on the result, the responsibility for what you ship.

Together: the way the sharpest people build today, as your own workflow from Monday morning.

The programme

The morning is Mikkel’s and Martin’s engine room, live. In the afternoon you work on your own code and your own tasks, with them beside you.

01 How Mikkel and Martin work, live

Two real tasks from start to finish on the big screen: Mikkel’s as a developer, Martin’s as a product person who builds himself. Which tools they use right now, how they fit together, and where they take over themselves.

02 The task before the code

The specification, the instruction file, the definition of done. How a long conversation with the model, before it writes a line, saves the day after.

03 The loop: the agent tests itself

Tests, end-to-end runs in a browser and clear exit criteria, so the agent fixes its own mistakes and you stop copying error messages back and forth.

04 Skills, prompts and setups

Mikkel’s and Martin’s own libraries: skills, instruction files and the prompts they use again and again. You take it home and set it up on your own machine on the day.

05 Several agents at once

Parallel agents in worktrees, agents in the cloud that send pull requests back, and how you keep track when three things are being built at the same time.

06 Your own code, your own backlog

The whole afternoon. You bring your own codebase and a couple of real tasks from the backlog. You give the agent context for the code, go from research through plan to implementation on one of the tasks and show the result at the end, with Mikkel and Martin at the tables.

07 What is left to be good at

When building is no longer the scarce part: taste, critical sense and responsibility. How you tell whether something is good, and what you do when it is not.

What you get

Mikkel built it himself

Mikkel thought outside the box with his talk and took the audience into the engine room.

Sofie Schrøder Lorentzen, Intelligent Automation, Nykredit (translated from Danish)

Mikkel stands out as a speaker with an exceptionally strong ability to explain.

Sebastian Mirkovic, AI Lead, Nykredit

It is clear that Mikkel knows what he is talking about.

Portrait of Mikkel Malmberg

Mikkel Malmberg

Has programmed since he was 12 and now puts agents to work on it. Runs the product studio Brainbow, founded 10er.com and made Mac apps such as Tuna and Leader Key. Used Claude Code from the day it came out and has since built everything from Rails apps to peer-to-peer software with agents. Works at GitHub Next day to day. Gives talks on AI for developers and organisations, among them Nykredit and Smartplan, and has been a host on Danish public radio and a stand-up comedian. Runs the developer’s engine room.

Portrait of Martin Ibsen

Martin Ibsen

Founder of Produktland, where he helps companies and product leaders improve their product development with AI. Product leader for 15 years, most recently Head of Product & UX at Energinet. Builds AI products every week with Claude Code, writes the playbook on AI product leadership and hosts the podcast of the same name, where Mikkel was a guest this summer. Builds everything himself with agents without being a developer: the site, Lyt, Skriv and the tools behind them. Runs the product person’s engine room, and is there for those in the group who build without a developer title.

Lynfabrikken, Aarhus
Group
8–12 participants, so there is time at the tables
Payment
Invoice after you sign up

We send you a confirmation and an invoice. There are 12 seats, first come, first served.

Do I need to be able to code?
You should have built something with an agent before and be able to read the code it writes. You do not need a developer title. Product people and designers who build themselves are welcome, and they are the ones Martin is there for.
Is it a beginner course?
No. The day starts where most introductions end. If you want to start from scratch, see the course for product managers first.
Which language is it taught in?
The open class is taught in English. A company class can be taught in English or Danish, as you prefer.
Which tools do we use?
The ones Mikkel and Martin use on the day, right now Claude Code and Codex. The principles apply to Cursor and the others too. You bring your own laptop and a subscription to at least one of the tools.
Can I bring my work code?
Yes, if your employer allows it. Otherwise you bring a side project, or we find a task on the day. Nothing you build leaves your machine.
Can my employer pay?
Yes. You get an invoice the company can pay.
How do I get my manager to say yes?

Three things you can write:

  • We already pay for the tools. The day is about getting out of them what the best get.
  • I come home with a setup the rest of the team can copy the same week.
  • The day costs less than one consultant day, and I build on our own code meanwhile.
Email you can forward

Hi [manager], I would like to attend a masterclass in building with AI agents, a full day with Mikkel Malmberg and Martin Ibsen, two of the people in Denmark who have built the most with Claude Code and similar tools. I bring our own code and come home with their setup (skills, instruction files, tests that run by themselves), which the rest of the team can copy. We already pay for the tools; this is about getting more out of them. It is on 18 January 2027 at Lynfabrikken in Aarhus and costs DKK 5,995 excl. VAT. There are 12 seats. Is it all right if I sign up? [your name]

If several of you come from the same team, there is a team price. Write to us, and we will work it out.

Sign up for 18 January. There are 12 seats.

Produktland episode 6 with Mikkel Malmberg

Produktland, episode 6, in Danish

Hear Mikkel on the podcast

Mikkel was a guest on the podcast this summer, and the day is built on that conversation: what changes when building becomes cheap, where he still takes over himself, and why taste, critical sense and responsibility count now.
