01
Solution discovery & simulation
We turn research into hundreds of working prototypes and simulations, covering alternative journeys, customer states, product settings, and edge cases.
Customers and teams experience them directly, shaping what moves into production.
02
Agentic product system
Agents turn committed product decisions into traceable engineering stories.
Evals check every story against the product definition, working prototype, and approved design, returning gaps and conflicts to the team before delivery.
03
Continuous learning
Research, prototype testing, usability sessions, client feedback, engineering input, product usage, failures, and business outcomes continuously update the product definition.
Each new signal shapes the next prototype, delivery decision, or change in direction.
Current role
An AI-first corporate venture builder.
What it is like to work together.
Words from engineers, founders, designers, and product peers I have worked with closely across teams and companies.

Marcus has an unbelievable drive and ambition paired with fantastic attention to detail. He's a quick learner, and our constructive discussions were often the highlight of my day.
Christian UhlDirector of Engineering, Conrad ElectronicFormerly PersonioFounder
Marcus has a rare combination of product vision, great communication skills, patience, and contagious passion. All this makes him the kind of leader people naturally want to work with.
Maciej ŁobodzińskiFounder & CEO, stoic.Y Combinator S19Product
In discussions where everyone had an opinion, Marcus would pull the conversation back to what we actually knew about the customer. I learned a lot about product judgment just from being in the room.

Marcus was my daily partner throughout the design process. His ability to make fast, effective decisions and passionately lead teams is a testament to his creativity and drive.
