John Clark is a B2B technology marketing executive who has spent much of his career helping organizations navigate transformation, particularly when markets, technology and customer expectations are changing at the same time. He currently leads marketing for Vonage’s Applications business and previously held senior marketing and GTM leadership roles locally at HERE Technologies, Genesys and IBM. Across those companies, John has led transformations spanning emerging technologies such as AI and IoT, mature billion-dollar software portfolios, and organizations working to reinvent how they go to market. A consistent theme throughout his career has been bringing GTM functions together around a clearer understanding of the buyer, then translating that understanding into differentiated positioning, simpler priorities and an operating model capable of executing them. His experience has taught him that transformation rarely happens as neatly as it appears in a strategy presentation: organizations have histories, incentives, silos, skills gaps and people who may understandably question why they need to change. John believes successful transformation begins with people rather than platforms: creating clarity, building capability and giving teams a meaningful role in the change. His work today increasingly explores how AI can accelerate that transformation without losing the judgment, empathy and customer understanding that ultimately determine whether the technology creates value.
