Agentio Raises $40M Series B to Scale AI‑Powered Creator Advertising Platform

Agentio, the New York City‑based AI‑native platform transforming creator‑led advertising, has secured $40 million in a Series B funding round as it accelerates its expansion and builds infrastructure to help brands scale creator advertising with enterprise‑grade efficiency. The financing brings the company’s total raise to approximately $56 million and values Agentio at around $340 million, underscoring strong investor confidence in its vision to modernize how brands work with creators at scale.

The Series B round was led by Forerunner Ventures, a San Francisco‑based venture capital firm known for backing consumer‑focused companies that reshape traditional business models. Forerunner’s leadership in this round reflects its strategic belief in the creator economy and the opportunity for Agentio to become a foundational platform for automating and scaling creator advertising.

Joining Forerunner in the investment were several key existing backers, including Benchmark, a Silicon Valley venture capital firm with a storied track record of early investments in category‑defining technology companies; Craft Ventures, a venture firm investing across early and growth stages; and AlleyCorp, a New York‑based investment firm that partners with early‑stage startups. Additional participation came from Antler and Starting Line, further strengthening the company’s investor base.

Founded in 2023 by CEO Arthur Leopold and CTO Jonathan Meyers, Agentio has quickly positioned itself as a leader in AI‑powered creator advertising by building a platform that automates the entire lifecycle of creator campaigns. The technology handles tasks ranging from creator discovery and matching to contract execution, performance tracking, and payments, allowing brands to scale creator programs with the same precision and accountability as traditional paid media channels.

Since its inception, Agentio has reported rapid growth, expanding its team and platform capabilities significantly. Over 100 enterprise brands, including some of the world’s most recognizable consumer names, have run creator campaigns through the platform, signaling early market validation and strong adoption among marketers seeking to diversify advertising strategies beyond conventional channels.

The new capital will be used to advance Agentio’s AI infrastructure, broaden its platform beyond YouTube into other major creator platforms, and expand its workforce from around 35 employees to over 100 in 2026. This expansion reflects the company’s strategy to build a scalable global platform capable of supporting brands and creators across diverse social ecosystems and formats.

Agentio’s approach addresses a longstanding challenge in the creator economy: how to transform personalized, relationship‑driven collaborations into predictable, measurable, automated advertising channels. By deploying AI to handle time‑intensive operational work, Agentio enables marketers to launch and manage creator campaigns in hours rather than weeks or months.

The company’s AI capabilities also help brands tailor creator matches based on audience fit and content alignment, manage campaign compliance, and gather real‑time performance insights — features that were traditionally manual and difficult to scale. For creators, the platform offers increased access to enterprise advertising budgets and a streamlined process for monetizing their content.

Agentio’s growth trajectory follows a series of earlier funding milestones, including a $12 million Series A round led by Benchmark in 2024 that helped it expand its platform and customer base. These successive funding rounds highlight sustained investor interest in the potential for creator content to play an increasingly central role in digital advertising.

As the creator economy continues to expand, with brands shifting more of their marketing spend toward authentic, influencer‑driven content, Agentio’s technology aims to be the infrastructure layer that powers this transformation. With $40 million in fresh capital and a strong cohort of investors backing it, the company is poised to scale its platform, support broader use cases, and further cement its role as a critical partner for brands navigating the evolving landscape of digital advertising.
