Agentio, a rapidly growing AI-powered creator marketplace, has successfully closed a $40 million Series B funding round led by consumer-focused VC Forerunner. This latest investment, which brings Agentio's total funding to $56 million and values the company at $340 million, will fuel its ambitious expansion beyond YouTube to integrate with Meta platforms and other social networks. The funding arrives amidst a booming creator economy, with sponsored video views on YouTube surging 28% year-on-year and the number of sponsored videos growing 54% in the first half of 2025, according to a Tubefilter report. This growth underscores a broader trend where ad spend through creator channels is steadily increasing, even projected to outperform traditional media in some sectors.
The Series B round saw participation from existing investors Benchmark, Craft Ventures, AlleyCorp, Antler, and Starting Line. Founded in 2023, Agentio is helmed by CEO Arthur Leopold, previously president at celebrity talent marketplace Cameo, and CTO Jonathan Meyers, a former Spotify engineer who led its automated content marketing team. The company has demonstrated remarkable growth, expanding fivefold since its last funding round in November 2024.
Brands leveraging Agentio's platform have reported significant improvements in campaign performance. For instance, socks and apparel brand Bombas achieved a 5.3x better return on ad spend (ROAS) and a 90% net new customer rate through Agentio campaigns, outperforming video ad spending on other platforms. Agentio also enables brands to deploy their ad budgets on Meta and Google in a matter of months, rather than the typical six-plus months, while yielding superior returns.
“The challenge historically before Agentio was for brands to partner with creators at scale. Our belief since we founded the company has been to use AI to automate the ad buying process for brands to get the best outcomes. As AI content has started to proliferate in people’s feeds, we are seeing that brands realize that this level of trust that creators have with their audiences is unbeatable,” said CEO Arthur Leopold in an interview with TechCrunch.
Agentio has already paid tens of millions of dollars to creators, though exact figures were not disclosed. The platform has proven highly beneficial for creators, with many doubling their brand partnership earnings within six months of joining. Furthermore, the time it takes for creators to receive their first bid has dramatically shortened from 45-50 days last year to less than a day currently, a testament to the platform's successful scaling and efficient matching of supply and demand.
AI-Powered Innovation and Expansion
Agentio's product development has heavily focused on integrating advanced AI, specifically reasoning models and multimodal understanding. This has led to the creation of an AI-powered campaign manager, a crucial tool that assists marketers in crafting effective campaigns—a feature now considered standard across most major ad platforms.
Building on its AI capabilities, Agentio previously launched an AI-powered feature to match brands with creators based on brand safety standards. This year, it introduced an AI-driven content review tool that automatically checks creator-submitted drafts to ensure they meet campaign briefs and are safe for publication.
“Previously, brands had to assign a person to watch every single creator video to make sure they were following the campaign brief,” explained CTO Jonathan Meyers. “Now, our agent checks all these parameters that save time for brands and allows them to roll out and scale campaigns rapidly.”
Meyers further highlighted that Agentio's advanced AI and improved profiling of both brands and creators have removed the need to restrict partnerships to conventional pairings. This data-driven matching enables Agentio to connect brands with creators who might have been traditionally overlooked. For example, a health supplement brand, typically partnering with fitness creators, might now be matched with outdoor enthusiasts through Agentio. While primarily serving consumer-centric brands, Agentio is also observing increasing demand from B2B organizations.
Having focused predominantly on YouTube for the past two years, Agentio is now beta testing integration with Meta platforms, with a particular emphasis on video formats such as Reels. The platform will facilitate brand-creator connections and leverage Meta partnership ads, which offer a discreet way to promote products or services without appearing in the main feed.
Agentio notes that many of its existing creators already have a strong presence on social networks like Instagram, which has streamlined the scaling of campaigns. Looking ahead, the company plans to extend its support to additional platforms, including TikTok and Snap, in 2026.
“We’d been tracking Agentio for over a year, building a relationship with Arthur and Jonathan by introducing them to some of our biggest brands, who immediately became customers and champions of the platform,” stated Eurie Kim, Managing Partner at Forerunner. “Unlocking multiple channels was a clear signal for us that Agentio could be the AI-powered media planning platform of the future, starting with the most valuable marketing asset of the future: creators.”
In line with its rapid expansion, Agentio has significantly grown its team from 12 to 35 employees since last year, with plans to exceed 100 employees within the next year.
