Agentio Raises $40M Series B to Scale AI-Native Platform for Creator-Led Advertising

Agentio, the AI-native leader in creator-led advertising, has secured a $40 million Series B funding round led by Forerunner to accelerate the infrastructure powering the shift of hundreds of billions in digital ad spend toward creators. The round includes participation from Benchmark, Craft Ventures, AlleyCorp, Antler, and Starting Line, bringing Agentio’s total funding to $56 million and valuing the company at $340 million.

“Advertising follows attention, and attention has moved to creators. The shift is already happening – brands are moving billions into creator-led marketing,” said Arthur Leopold, co-founder and CEO of Agentio. “What’s been missing is infrastructure that lets brands scale creator programs the way they can easily scale their search and paid social campaigns – thereby 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. This new funding will allow us to expand that infrastructure globally and across platforms, establishing Agentio as the most important growth engine for brands, and unlocking the movement of hundreds of billions of dollars into the creator economy.”

Agentio’s AI-driven platform automates every step of the creator advertising lifecycle-from creator discovery and matching to content briefs, brand safety checks, bidding, contracting, approvals, payments, and real-time analytics. This end-to-end automation allows brands to scale creator programs with the same precision, speed, and control as other digital media channels while giving creators frictionless access to enterprise-level budgets. In 2025 alone, more than 100 enterprise brands—including Uber, Tecovas, DoorDash, CashApp, and Olipop-have already diverted tens of millions from traditional paid media into creator campaigns powered by Agentio.

“Every previous attempt to scale creator advertising required armies of people negotiating individual deals. It couldn’t work at the scale brands needed,” said Jonathan Meyers, co-founder and CTO of Agentio. “What’s changed is that AI can now automate the manual administrative tasks that once took weeks or months. Marketers can train custom agents in natural language to translate their ideas into fully contracted creator campaigns in minutes. Our platform analyzes a brand’s needs, evaluates tens of thousands of creators for audience and content fit, determines optimal matches, and automates the entire workflow, from brief to payment. This end-to-end automation is powered by the underlying technology, network, and data on Agentio that turn creator marketing into a scalable system.”

Agentio’s platform functions as a two-sided network: brands gain powerful agentic tools to automate and scale creator campaigns, while creators receive tailored opportunities from leading brands without the delays and back-and-forth typically involved in partnership negotiations. The company has achieved more than 5x year-over-year growth, with many brands reporting outperforming results compared to their best digital ad channels. Bombas, for instance, recorded a 5.3x higher ROAS through Agentio campaigns compared to digital video alternatives.

“Creators have become one of the most powerful forces shaping consumer behavior, but the infrastructure to support them hasn’t kept pace,” said Eurie Kim, Managing Partner of Forerunner. “Just as Google and Meta built platforms to unlock search and social, Agentio is building the infrastructure needed for creator-led ad development and monetization at scale. Arthur and Jonathan recognized early on the opportunity for AI to bridge the execution gap between creators and marketers, and we believe the Agentio platform will power the next generation of efficient, scalable marketing alpha in the ever-evolving competition for customer acquisition and awareness.”

Several companies in Forerunner’s portfolio-including Warby Parker, Away, Chime, and The Farmer’s Dog—are already running high-performing creator campaigns through Agentio.

“Agentio completely transformed our YouTube creator strategy,” said Steven Vigilante, Director of Media and Partnerships at Olipop. “What used to require months of coordination for a handful of partnerships now happens in days, allowing us to activate dozens of top-tier creators while improving performance tracking. For the first time, we can scale this channel and measure the ROI on every dollar spent, just as we would with any paid media channel.”
