Jay Sullivan is the CEO of Fandom, the world's largest fan platform with 350 million monthly visitors spanning wikis, gaming, movies, TV, and pop culture. A Yale-trained applied mathematician turned product visionary, Sullivan built his career shepherding the open web at Mozilla—where he served as SVP of Product, COO, and Interim CEO—before stints driving product at Groupon, Facebook's Reality Labs AI team, and Twitter's consumer and revenue products.

Since joining Fandom in February 2026, he is steering the company from a Google-traffic-dependent reference destination toward a real-time, AI-powered fan engagement platform.
