IAB Joins Jupiter Festival Miami as Founding Partner
The Interactive Advertising Bureau (IAB) has joined Jupiter Festival Miami as a founding partner ahead of the festival’s debut from October 6–9, 2026. William Mellis, Jupiter Festival Miami CEO and founder, said the festival was conceived 15 months ago to explore the future of content across media, entertainment and sport. IAB CEO David Cohen said the organization joined to help shape programming and may secure an IAB-specific stage; this is IAB’s first festival partnership before a launch during Cohen’s six-year tenure. Other partners include Boston Consulting Group and MCH Group (which owns a 20% stake). The festival’s announced speaker lineup includes executives from Tribeca Enterprises, Whalar Group, Known and M+C Saatchi. Organizers aim for a 5,000-person attendance benchmark after high website interest during Cannes Lions week.
Industry partnership expands a new industry-focused festival and creates programming influence opportunities for IAB, but it is not a platform-level policy or product change and has limited immediate impact on core AdTech infrastructure or market operations.

Mellis launches Jupiter festival with new events model
William Mellis, the veteran behind Money20/20's revival, has launched the Jupiter festival in Miami, a new media, entertainment, and sports event. He critiques the traditional trade show model, which he says maximizes revenue from the show floor at the expense of the delegate experience. Jupiter focuses on video content and aims to create an environment conducive to serendipitous connections, with fewer booths and more lounges, entertainment, and dining. The festival is heavily invested in its first year, with a target of breaking even next year. MCH Group, the company behind Art Basel, has acquired a 20% stake in Jupiter Festival Miami. Mellis aims for attendees to leave with three new ideas, six useful contacts, and a nine-out-of-ten experience.
