When the world talks about the creator economy, most conversations still focus on virality and entertainment. But behind the scenes, a new wave of data-driven platforms is quietly reshaping how brands and creators collaborate at scale—and AI is sitting at the center of it.
Agentio, the AI-powered creator marketplace founded in 2023, has secured $40 million in Series B funding, marking its third raise in three years as demand for creator-driven advertising accelerates. The round was led by Forerunner, with participation from Benchmark, Craft Ventures, AlleyCorp, Antler, and Starting Line—bringing the company’s total funding to $56 million and valuing the business at $340 million.
The funding comes at a pivotal moment for the creator economy. According to Tubefilter, views on sponsored YouTube videos climbed 28% year-on-year, while the number of sponsored uploads surged 54% in the first half of 2025. More brands are shifting budgets away from traditional media and toward content creators who hold stronger audience trust and conversion power.
Agentio was founded by CEO Arthur Leopold, formerly President at Cameo, and CTO Jonathan Meyers, a former Spotify engineer who helped lead automated content marketing initiatives. Since its previous funding round in late 2024, the company reports 5x growth, driven by brands seeking measurable ROI in a fragmented digital landscape.
That ROI has been notable. Agentio highlights cases such as apparel brand Bombas achieving a 5.3x improvement in return on ad spend and 90% net-new customers from Creator campaigns. Brands that typically need over six months to deploy full ad budgets on Meta or Google are able to do it in just a few months through Agentio—often with stronger outcomes.
Leopold says automation is the missing piece brands have struggled with for years. “The challenge before Agentio was scale,” he explained. “AI now allows us to automate the ad-buying process and match brands with creators who convert—especially at a time when audiences trust creators more than ever.”
Agentio says it has now paid tens of millions of dollars to creators and continues to compress time-to-value. In 2024, creators joining Agentio usually waited 45–50 days for their first brand bid. This year, that has dropped to under 24 hours, driven by better supply-demand balance, more campaigns, and improved AI-based matching.
On the product side, the startup has rolled out several AI capabilities, including a reasoning-enabled campaign manager and multimodal content analysis tools. One of its newest features is an AI-powered content reviewer that checks whether a creator’s draft meets brand guidelines and safety standards.
“Before this, brands had to manually watch every single video to check compliance,” said CTO Jonathan Meyers. “Now, our system handles that workload, allowing campaigns to scale far more efficiently.”
Agentio’s matching model has also broadened the types of creators brands can work with. For example, brands in niches like health supplements are no longer limited to fitness channels—the platform identifies non-obvious creator segments such as outdoor or lifestyle communities that still deliver strong conversion signals.
While YouTube remains the company’s primary engine, Agentio is now beta-testing campaigns across Meta platforms, especially Reels. Many creators already have strong cross-platform presence, enabling brands to scale campaigns seamlessly across multiple channels. TikTok and Snapchat integrations are planned for 2026.
Forerunner managing partner Eurie Kim, who led the round, said the firm has been tracking Agentio closely:
“Unlocking multiple channels showed us Agentio has the potential to become the AI-powered media planning platform of the future—built on the most valuable marketing asset ahead: creators.”
Agentio has grown from 12 employees to 35 in less than a year and plans to expand headcount to 100+ over the next year as it scales product development, engineering, and creator operations.
