After six years as Fandom’s CEO, Perkins Miller is parting ways with the popular wiki hosting platform.

While there has yet to be an official announcement, The Verge has learned that Miller is no longer working for Fandom as of last week. In a statement sent to The Verge on Fandom’s behalf, Katie Schroeder confirmed Miller’s departure and noted that, while the company is currently being overseen by interim leadership, “we have not announced a new CEO as of yet.”

While Fandom’s IP-specific wikis are popular, they have become widely known for being difficult to navigate due to a preponderance of aggressive ads that often make pages unstable to the point of being nearly unusable. When asked about Fandom’s user experience during a Decoder episode back in 2023, Miller said that he thought “we’re doing our best to make it as elegant as we can, and yet, we need to drive the economics.”

Though Fandom hasn’t named who might replace Miller, the PlayOn! Sports Network — which aggregates videos of high school organized sports — announced today that he has signed on as its new CEO.
