Digital media company Underknown has announced a merger with creator agency GPOP, marking its third acquisition in three years. 

The deal combines Underknown’s content portfolio, which includes shows like “What If,” “Aperture,” and “How to Survive,” with GPOP’s creator-focused agency services.

GPOP, launched one year ago by former VidCon COO and CSO Michael Gardner and co-founder Yaz Narcin, serves nearly 20 non-fiction media creators with a combined YouTube following of approximately 100 million subscribers. The agency specializes in revenue and audience growth strategies for its creator partners.

Underknown brings significant scale to the merger, operating 90 channels across ten languages with over 75 million subscribers. The company reports 80 million monthly active viewers and ranks among digital media’s top three largest factual producers.

Narcin will assume the role of Managing Director at GPOP as part of the transaction. Gardner, who briefly worked for MrBeast before returning to GPOP, will take on a dual position as GPOP co-founder and Executive Vice President of Partnerships at Underknown.

“GPOP’s merger with Underknown means we can now share our innovative solutions with more companies while finding fresh ways to generate revenue for Underknown and all of GPOP’s partners,” said Underknown CEO Steve Hulford in a news release.

“We didn’t just want a bigger slice of the pie; we wanted to create a pie that could empower the creator economy,” Gardner added. “With Underknown’s support and resources, we’re bringing new opportunities and tools to creators everywhere.”

The companies have not disclosed the financial terms of the merger.
