We’re Building the Most Important Growth Engine for Brands: Agentio’s Series B

Today, we're announcing that Agentio has raised a $40 million Series B led by Forerunner, with continued backing from Benchmark, Craft Ventures, AlleyCorp and other leading investors. This brings our total capital raised to $56 million and values the company at $340 million - just 2 years after launching our platform and following 5x year-over-year growth.

This is a story about a fundamental shift in how advertising works - and how Agentio is building the infrastructure to power it at scale.

To our team, our brand and creator partners, our investors and supporters: thank you. This funding, our growth, and our vision is only possible because of our world-class, customer-obsessed, insatiably curious, and wildly ambitious team, and our partners who believe deeply in Agentio. We're hiring world-class engineers and GTM operators who want to build infrastructure for an $800B market being created in real-time. Come build with us.

The Problem: An $800B Opportunity That Couldn't Scale

Attention has moved to creators. Consumers don't find relevance in banner ads or traditional advertising - they trust the people they follow, whose recommendations feel authentic, whose content they actively choose to watch. The creator economy is projected to reach $500 billion by 2027. Unilever's CEO recently stated that 50% of their marketing budget will shift to creators. 94% of Gen Z trust influencer recommendations more than traditional ads, and 77% have made purchases based on creator recommendations. The signal couldn't be clearer.  

Yet despite creators' outsized influence on purchasing decisions, less than 2% of digital ad spend has shifted to creators today.

Why? Because executing creator advertising has been fundamentally broken and impossible to scale.

Every campaign required weeks or months of manual work: finding the right creators, negotiating individual deals, managing contracts, coordinating content approvals, measuring performance across inconsistent data. Marketing teams could manage maybe a few dozen creator partnerships per quarter. Scale to hundreds or thousands? Impossible without an army of people handling spreadsheets, email threads, and manual tracking.

The math was brutal: creator advertising consistently outperformed traditional digital channels by 3-5x, but brands could typically only allocate ~2% of their budgets to it because the infrastructure to scale simply didn't exist.

Brands recognized the opportunity but couldn't operationalize it at the scale their budgets demanded. Creators wanted access to the $800 billion in paid media spend (versus the ~$10 billion of brand dollars currently flowing to them), but couldn't navigate the fragmented, manual process.

Before Agentio, both sides wanted this shift to happen. Neither could make it work. This is the gap we built Agentio to close. It’s why Forbes recently named us one of the Next Billion Dollar Startups.

What We've Built: AI-Native Infrastructure That Makes Creator Advertising Scalable

We've spent the last two years building something that didn't exist before: end-to-end AI infrastructure that enables marketers to build and scale creator programs with the same efficiency, speed, measurement, and control as any digital media buy.

Our platform analyzes a brand's goals, evaluates tens of thousands of creators for audience fit and content alignment, determines optimal matches, and automates the entire workflow - from brief creation to creator matching, brand safety checks, contracting, content approval, real-time performance tracking, payments, and mid-flight campaign optimization. What used to take marketing teams weeks or months now happens in minutes.

Marketers can train custom AI agents in natural language to translate campaign ideas into fully contracted creator programs. Creators get personalized brand opportunities that match their content and audience - no endless back-and-forth, no negotiation headaches, just seamless collaboration with the world’s most exciting brands.

The result? Brands can finally build creator programs that run at the scale of their paid media budgets. Creators get systematic access to paid media budgets. The proof is in the performance - It’s why brands and creators LOVE Agentio - just check out our G2 Reviews.

The Results: Real Budgets, Real Performance

In 2025 alone, over 100 enterprise brands - including Uber, DoorDash, Mint Mobile, CashApp, Bilt Rewards, Vuori, David Protein, Coterie, The Farmer's Dog, and Olipop - have shifted tens of millions of dollars in paid media spend to creator campaigns built on Agentio. We've grown 5x+ year-over-year, and the companies using our platform are seeing results that fundamentally change how they think about customer acquisition.

Bombas achieved 5.3x better ROAS from Agentio campaigns compared to their digital video campaigns. These aren't marginal gains. They're the kind of performance differences that drive CMOs to rethink their entire media mix.

"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."

Why This Shift Is Inevitable: Network Effects And A Compounding Data Moat

The shift to creator-led advertising isn't a question of if - it's a question of when and through which platform.

What makes Agentio uniquely positioned to power this shift are the network effects we're seeing compound in real-time:

More brands attract more creators. When enterprises like Uber and Mint Mobile run campaigns on Agentio, top creators see consistent, well-paid opportunities from premium brands. This draws more high-quality creators to the platform.

More creators attract more brands. As our creator network expands, brands get access to better matches, faster campaign launches, and more inventory to scale their spend. This makes Agentio increasingly valuable as the only place where they can operationalize creator advertising at the scale their budgets demand.

More campaigns make the AI smarter. Every campaign on Agentio generates thousands of data points that improve our matching algorithms, pricing models, and performance predictions. Performance compounds, and creator matching improves with each additional campaign.

This is why we can power this shift in the ad spend that inevitably follows consumer attention and trust - and why it will flow through infrastructure that creates positive network dynamics. Agentio is building that infrastructure and seeing these effects compound in real-time, benefiting both brands and creators.

Why Forerunner: The Perfect Partner for What's Next

When we spoke with investors for this round, we were looking for more than capital. We needed a partner who understood that we're building foundational infrastructure for how hundreds of billions of dollars will flow through the creator economy, and had a unique understanding of our customer base.

"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 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."

What makes this partnership especially powerful: many Forerunner portfolio companies - Warby Parker, Away, Chime, The Farmer's Dog, etc - already run successful creator programs on Agentio. They've seen firsthand how this infrastructure transforms marketing. That conviction from the operating side is what led to conviction from the investing side.

Eurie and the Forerunner team understand what we're building at a fundamental level: not just another adtech tool, but the essential infrastructure layer that makes the largest shift in advertising spend in a generation actually possible.

Our Vision: The Essential Growth Engine for the Next Decade

We're building the platform and infrastructure that unlocks the largest shift in advertising spend in a generation.

Digital advertising will be transformed to be creator-led, leading to hundreds of billions of dollars to move to creators from traditional and digital advertising channels over the next decade. That capital will flow through a platform that enables advertising spend to be scalable, measurable, and efficient. Agentio is building that infrastructure - the AI, the network effects, the automation - that makes creators a core part of every brand's growth strategy, not an experimental side channel.

This means we can become the most important growth engine for both sides of the market:

For brands: the platform that unlocks their best-performing marketing channel and makes it as easy to scale as any paid media buy, with the measurement rigor they demand and the efficiency their boards require.

For creators: the infrastructure that gives them systematic access to enterprise budgets, turning creator marketing from sporadic one-off deals into a sustainable, predictable business with consistent revenue streams from premium brands. We enable a large part of the creator economy to live off their work, and pursue their creative passions. 

What's Next: Scaling the Infrastructure Globally

This funding will let us expand beyond YouTube to Meta Partnership Ads and additional platforms. We're also growing our team from 35 to over 100 employees in NYC to support this expansion and our global growth.

Attention has already moved, and ad dollars always follow attention. The only question was whether the infrastructure would exist to make this shift happen at scale. We've built that infrastructure, and now, we're scaling it to power the growth of brands and creators globally!
