Brian Stempeck is the CEO and co-founder of Evertune AI, a New York startup that helps brands measure and improve how they show up inside AI models like ChatGPT, Gemini, Claude and Perplexity.

Tim Mahlman is the CEO of Narrative I/O, a New York-based data collaboration platform that lets companies buy, sell, and share data as easily as sending an email. He took the top job in May 2023 after a 25-plus-year run through the plumbing of digital advertising: founding member of one of the first ad networks in 1996, co-founder of the video exchange Vidible, president of platforms at AOL and then Verizon Media where the division grew from $1.5B to $4B, and president of the pet-health startup Petabyte before it was acquired by Chewy. He splits his time between New York City and the Bay Area.

Two decades earlier he built BuzzMetrics, the company widely credited with inventing social media analytics, then sold it to Nielsen and ran Nielsen Digital. He has been chief revenue officer at both Vevo and The Trade Desk, and now spends his days explaining to studios, networks and Wall Street why people sign up for streaming services - and why they leave.
