Jesper Vieveen is Customer Success Director at OpenUp, Europe's market leader in preventative mental wellbeing at work, used by more than 2,000 organisations and over 1.5 million people. As OpenUp's first commercial hire, he helped take the company from zero to 2,000 clients and led its shift from a consumer product to an enterprise platform. He now owns the systems behind retention and expansion — and, more fundamentally, the question that defines the category: not whether mental-health support exists, but whether people actually use it. With eight years in B2B SaaS, he works at the intersection of behaviour change, technology and commercial scale, turning access into measurable resilience across an entire workforce.
