Summary
👤
Senior🎓
Top SchoolKristofer Espinosa is a Franco-Swedish entrepreneur and engineer with eight years of cross-disciplinary experience building product-driven startups and technical solutions. As co-founder and CEO of Kollin, he grew a digital study-coach used by 10,000 students across Swedish engineering schools, tackling procrastination through product design and behavioral insights. His background blends industrial engineering, energy systems research, and hands-on web development (Le Wagon), enabling him to move between strategy, data-driven experimentation, and building MVPs. Past roles at Fortum, VINCI Energies and Solorea show his ability to translate technical analysis into commercial and operational impact across energy and cleantech. Comfortable in multicultural environments, he combines entrepreneurial grit with a generalist’s curiosity—equally at home sketching product flows, coding features, or pitching partners.
