“Peter is nothing short of a top-notch designer who has seriously propelled Klarna becoming the world's #1 shopping destination through first-class design and phenomenally thought-through user experience, driven by both his expert eye for design and consistently accurate view, but also informed by data and what performs.”

Lead design partner. One person. Founder speed
I'm Peter Marc. I help founders and product teams turn rough ideas and half-built MVPs into something their team can actually test, pitch, and ship, in weeks, not quarters.
Clarity first. Then something your team can ship
I started in agencies and moved into product teams because I wanted to see what I designed actually work. Fifteen years later, the work is the same at the core: reduce ambiguity, make decisions under constraint, and ship something a real team can build.
I've led design systems, onboarding flows, and zero-to-one products at companies where unclear UX costs real money: Klarna , Rakbank , Guesty , Wolt , EasyPark , Amazon . That's not a list for name-dropping, it means I've worked in fintech compliance, payment flows, mobile-first at scale, and multi-platform consolidation.
I don't work through briefs or a PM acting as translator. I sit in the problem with the team, from the rough idea. One person, no account manager, no handoff chain. What you send me comes back as a decision, a flow, or a prototype.
I use AI tools as part of how I work, not as a marketing angle. The feedback loop between product direction and prototype is shorter than it used to be. I also build my own products, Daygrain is my current iOS experiment. Building solo forces product judgment that consulting alone doesn't.
I work best with founders and product leads who want direct feedback, not polished decks. If you're looking for someone to execute a spec, I'm probably not the right fit. If you're looking for someone to help figure out what the spec should be, we should talk.

From the people I've worked with
“Peter very quickly established himself as a key member of the team, embedding himself in the problem space and leading user research efforts. Throughout our time together I've been thoroughly impressed by his ability to quickly adapt his approach depending on the context.”
“What stood out about Peter was his balance of visual craft and practical product thinking. He cared about clarity and consistency, not just aesthetics. He also brought strong systems thinking, particularly around design systems, reusable components, and scaling across English and Arabic.”
