Agentio raises $40 million to build the “infrastructure” that powers the creator marketing industry

For the third year in a row, Agentio has announced a significant funding round. The latest coup for the AI-driven creator ad platform is a $40 million Series B that values the company at $340 million.

As its name implies, Agentio equips brands with “agentic” tools that can automate key facets of the influencer marketing process. By working with a network of “many thousands” of creators, Agentio plays the matchmaker between forward-thinking brands and social media stars who can boost those sponsors’ messages. As a result of that process, brands like Uber, DoorDash, and CashApp have allocated “tens of millions” of marketing dollars to Agentio’s platform, according to a press release that accompanied the Series B announcement.

Agentio is not the first company to ply its trade in the contact zone between creators and brands, but it has established a prominent position in an influencer marketing industry that continues to grow year-over-year. Brands are spending more on platforms like YouTube, with eMarketer estimating that U.S. buyers will spend $10 billion on sponsored content in 2025 alone. Findings from our data provider Gospel Stats have shown that the number of sponsorships on YouTube is up 54% year-over-year.

When you look at the numbers those campaigns put up, it’s not hard to see why brands are so invested. Leading pieces of sponsored content can reach seven-digit view counts in just a few days, and that’s just on YouTube.

Agentio’s ability to facilitate those partnerships has helped it attract interest from VC firms. Following a $4.25 million seed round in 2023, Co-Founders Arthur Leopold (formerly of Cameo) and Jonathan Meyers (ex-Spotify) landed a $12 million Series A last year. The Series B, which accounts for Agentio’s fivefold growth since its last round, brings the company’s total funding up to $56 million.

“Advertising follows attention, and attention has moved to creators. The shift is already happening — brands are moving billions into creator-led marketing,” Leopold said in a statement. “What’s been missing is infrastructure that lets brands scale creator programs the way they can for search and paid social campaigns — and making creators part of their media plan. We’ve built that infrastructure. Brands can now build creator programs on Agentio that run at the scale of their paid media budgets.”

So what’s next? Leopold said that Agentio will use its fresh funding to continue building up its infrastructure. Pacts with companies like Meta are in the works, and Agentio will also expand the size of its team. The plan is to jump from 35 employees to 100 in 2026, so we can expect Agentio to continue betting on the sustained growth of the creator economy.
