About

With 10+ years of experience scaling technology ventures across Europe, I specialise in building and executing go-to-market strategies that turn market opportunities into sustainable growth & revenue. I've helped category-defining companies (including Klarna, Airwallex, and iZettle) expand into new markets, build strategic partnerships, and grow commercial operations from the ground up. What drives me is working on products and in industries where the stakes feel real and where technology genuinely changes how businesses operate. Outside of work, I enjoy discovering new music and cultures, movies, padel, and exploring the world with my motor. 📩 [email protected]

    Windmillkey was an eCommerce project I co-ran with a friend. We migrated the website from WordPress to Shopify, where I primarily managed the channel distribution network and handled company bookkeeping. We transitioned our accounting software from E-boekhouden to Moneybird. In January 2024, we sold Windmillkey to new owners.
