Katerina Klezlova
Katerina helps technology companies turn complexity into commercial success. She is a venture builder, board advisor, and strategic operator working across MedTech, DeepTech, and SustainabilityTech, with a strong focus on regulated industries and growth-stage companies. Over the past decade she has built her own ventures and advised hundreds of founders on commercialization strategy, market entry, fundraising readiness, and investor due diligence.
Through Fortuny Consulting, she works hands-on with startups and scaleups across Europe — often stepping in as external co-founder, interim COO, or strategic capital advisor. She has reviewed hundreds of investor decks, supported leadership teams through fundraising processes, and helped companies position themselves credibly for institutional investors.
Alongside her advisory work, Katerina serves as a Non-Executive Director, startup jury member, speaker, mentor, and coach for accelerators and incubators across Europe.
Current focus: board and advisory roles in growth-stage tech, external co-founder and strategic operator partnerships, fundraising, commercialization, and leadership strategy.
