Johan is CEO and co-founder of Voxo, an AI-powered event content platform that turns live sessions into branded summaries, reports, podcasts and searchable chatbots in real time. Voxo works with Informa, GitHub, ServiceNow, HPE, Intuit and Workday on events ranging from 100 to 1,000+ sessions, and was Event Tech Live's official AI partner in 2024. He focuses on helping organisers extend the life — and revenue — of their content well beyond the live moment.
