Jupiter Festival, a new Miami Beach conference launched by Cannes Lions alum William Mellis and former Fox Sports Media Group CMO Eric Markgraf, opened this week with backing from Art Basel parent MCH Group, which owns 20% of the venture.

Cannes Lions, YouTube, Boston Consulting Group, and the Interactive Advertising Bureau also backed the launch. The founding lineup positions Jupiter as a highly ambitious play for industry dollars in a conference circuit that is already packed.

The event ran across four days and three stages. It hosted discussions between media, entertainment, sports, and advertising leaders on three core themes:

• Creators and the attention economy
• Fandom and sports rights
• AI's impact on creative and discovery

Who is behind Jupiter Festival?

The founders bring credentials from two corners of the industry. William Mellis built his career inside Cannes Lions, the advertising festival that anchors the global awards circuit. Eric Markgraf served as CMO of Fox Sports Media Group.

Their investor base spans art, advertising, consulting, and platform media. MCH Group, the Swiss parent of Art Basel, holds a 20% stake in the venture — a signal that the company sees a commercial events opportunity beyond the art world.

What did the first edition cover?

The programming reflected the founders' thesis about where industry attention is moving. Panels put media, entertainment, sports, and advertising executives in the same rooms to debate creators, fandom, sports rights, and AI's effect on how creative work gets made and discovered.

The format — four days, three stages — mirrors the scale of established fixtures rather than a boutique startup gathering. That scale, combined with sponsor names like YouTube and Cannes Lions, signals the founders' intent to compete for a share of marketing budgets already committed to existing conferences.

Why does the launch matter for marketers?

Jupiter enters a market where event dollars face intense competition. The festival's mix of backer categories — a trade-body veteran in Cannes Lions, a platform in YouTube, a consultancy in Boston Consulting Group, an industry association in the IAB, and an events conglomerate in MCH Group — suggests the venture is courting multiple streams of industry spending at once.

For sponsors and attendees, the question the first edition had to answer was whether a new Miami Beach event could carve out a distinct position. The founders' bet rests on programming that fuses sports, entertainment, and creator-economy themes under one roof — territory that incumbents have historically treated separately.
