About

I’ve spent my career simplifying complexity—first as VP of Product at Doodle.com, where I discovered my passion for user-centered design. That passion led me to found TestingTime, the first on-demand test user recruitment platform for UX research. We built a trusted service used by leading product teams across Europe and scaled it to 1 million test users before successfully exiting to Norstat. Since stepping away from TestingTime, I’ve shifted focus to early-stage investing, backing startups in AI, fintech, healthtech, and sustainability. I'm also a lecturer in Human-Computer Interaction Design, sharing what I’ve learned with the next generation of UX leaders. Now, I’m open to new ventures where I can bring product and UX strategy to life—through building, advising, or investing.
