Agentio secures $40M to expand AI-driven infrastructure for creator-led advertising

Agentio has raised $40 million in Series B funding to advance its AI-native platform designed to automate and scale creator-led advertising, marking one of the larger investments in the rapidly expanding creator economy. The round, led by Forerunner with participation from Benchmark, Craft Ventures, AlleyCorp, Antler, and Starting Line, brings the company’s total capital raised to $56 million and places its valuation at $340 million.

The investment comes as brands increasingly shift paid media budgets toward creator-driven campaigns, even as the broader ecosystem remains constrained by manual, fragmented workflows. Despite creators’ growing influence on consumer behavior, less than 2% of digital ad spend currently flows to them—a gap Agentio says stems from operational barriers such as time-intensive negotiations, inconsistent measurement, and limited scalability.

Agentio positions its platform as an automated alternative to the traditional piecemeal approach. The company uses AI to streamline every phase of a creator campaign, from identifying suitable creators and generating briefs to handling brand safety checks, contracts, payments, and performance reporting. The model is built to mirror the speed and predictability of programmatic ad buying, but for creator content.

CEO Arthur Leopold said the company’s goal is to make creator-led advertising a standard part of every media plan by giving brands tooling that functions like existing digital ad systems. According to the company, more than 100 major brands—including Uber, DoorDash, CashApp, Olipop, and Tecovas—shifted significant portions of their budgets to creator programs managed on Agentio’s platform this year. Some advertisers have reported stronger returns; Bombas, for example, saw over a fivefold improvement in return on ad spend compared with previous digital video buys.

Agentio’s infrastructure also functions as a two-sided marketplace, providing creators with automated access to enterprise budgets without the need for extensive outreach or negotiation. The platform evaluates thousands of creators for audience fit and performance potential, recommending matches based on both brand requirements and creator interests. According to CTO Jonathan Meyers, the system adapts to ongoing feedback, refining recommendations based on past campaigns.

While Agentio currently focuses primarily on YouTube, the company plans to broaden its integrations. Early tests with Meta Partnership Ads have shown encouraging results, and the company intends to expand support for additional platforms in 2026. The new funding will also go toward growing the workforce from 35 to more than 100 employees.

Agentio is betting that fully automated creator marketing could unlock significantly greater ad spend, mirroring the shift that once moved dollars toward search and social. Investors share that view, casting Agentio as the infrastructure layer needed to support the next major wave of digital advertising.
