When everyone can make things, taste is the differentiator.

AI raises the floor for everyone. But not the ceiling. In this era, taste and judgement are the real currency — knowing what's worth building, and caring enough to build it right. I've spent 15 years leading teams and staying close to the craft. That's what I bring to the work.

Design at scale

Design at scale means getting design a seat at the table — not just delivering outputs from a distance. It means shaping product direction alongside PMs and engineering leaders, making sure user insight drives decisions before a single pixel is placed.

02

Player-coach

I'm a player-coach — and it's always been how I lead. I hire for talent density, mentor closely, and stay in the work alongside my team — not managing from a distance. I've led 25+ designers across agencies and in-house teams, and I still believe the most powerful thing a design leader can do is help someone grow into a version of themselves they didn't know was possible.

03

Product strategist

The best design decisions I've made weren't about how something looked. They were about what to build at all. I sit at the intersection of product thinking and design craft — knowing what we should be building, how it connects to where the business is going, and how all the pieces fit into something coherent.

Formalize

Building the design function from zero at a hyper-growth compliance startup.

Joined as the first design leader on a platform still shaped largely by engineering priorities. Reoriented the product around user journeys, information architecture, and ease of use — shifting from developer-led to genuinely UX-led thinking. Hired a team of four, built the design system from scratch, and now own the full product experience end to end.

Maersk

Maersk

Took design from an afterthought to a strategic function — across one of the world's largest logistics platforms.

Doubled the team from 6 to 12 in six months and restructured it into three focused functions: Product Design, Design System, and Research. Advocated design out from under Technology and into Product — a structural shift that changed how design influenced decisions at every level.

No assholes

Work takes up too much of your life to spend it with people who make it miserable. The culture I care about building is one where we bring a bit of ourselves to work. Where we tell stories, form real relationships, and show up for each other. Vulnerability creates safety. Safety creates the conditions for genuinely great work.

Guardian of positivism

Someone once called me a guardian of positivism — I'll take it. I genuinely believe that energy is contagious, and that a team with the right attitude consistently outperforms one without it. "Yes, and..." over "no." I've finished three Ironmans and race competitively in Master A. The "never, ever give up" attitude that gets you across that finish line is the same one that keeps a team moving when things get hard.

Craft and care

I'm fascinated by things that are excessively well made — in the digital and physical world. When you can feel that someone truly cared about making an experience as good as it could possibly be. That's what I want to build. Not for the sense of accomplishment — but because users choose you over the competition when you genuinely solve something in their lives.

Mikkel is a rare breed of design leader who doesn't just manage pixels—he scales product vision. As Head of Engineering, I had a front-row seat to his impact. He built a comprehensive, cutting-edge design system entirely from scratch, completely elevating our frontend velocity and aesthetic standards. Mikkel has an unparalleled eye for talent, single-handedly recruiting a world-class design team that consistently punched above its weight. He was absolutely instrumental in shipping critical, high-stakes features for both our Formalize and Whistleblower software. Beyond his craft, Mikkel was the ultimate bridge between Product, Design, and Engineering, always dismantling silos to find the absolute best solution for the product. Any company lucky enough to land him next is getting a transformative leader.

Mikkel has strong user-focused design thinking and a lot of energy in how he works. Across multiple product cycles, he always pushed for high quality in design iterations and made collaboration between product, design and engineering very smooth. What I appreciated most was his ability to create alignment and momentum in a stage where the product organisation was still forming. His empathy, team-first mindset, and practical way of working made him a very strong partner in building how we worked across functions.

Mikkel brings a rare combination of strong design craft and the ability to simplify complexity. He consistently found ways to break messy problems down into simple, practical concepts — his storytelling made alignment feel easy. Together we co-created a design system, defined page recipes, and established UX principles that gave teams clarity and direction, enabling a full navigation and UI overhaul delivered without compromising quality. As someone responsible for raising the bar on experience, I've worked with many strong profiles. Mikkel stands out. He raises the standard in a way that lasts, both in the product and in the team.

formerly Senior Platform Product Owner, Maersk

Mikkel was one of the first leaders I'd worked with who truly understood the strategic value of research. He didn't just make space for it — he integrated it into how the team operated, and made sure our findings shaped direction rather than just informed delivery. Mikkel is one of the best strategic designers I've had the pleasure of working with. While his design expertise is exceptional, his true strength lies in his leadership. He has a rare ability to bring out the best in people, creating an environment where individuals grow, take ownership, and thrive. Working with Mikkel makes you a better and braver designer, a strong believer in teamwork, and a more confident professional. His quiet optimism and endless curiosity are as contagious as they are powerful.

It was an absolute pleasure to have worked with Mikkel on the same design team. He created a highly supportive environment where the UX team could thrive, guiding us with both empathy and clear strategic vision. One of his greatest strengths is his ability to tackle messy, complex UX problems and help guide the team toward simple, impactful solutions. He is an exemplary leader who genuinely cares about his people.
