Agentio is an AI-native creator advertising marketplace, founded in 2023 and headquartered in Brooklyn, New York, that automates the end-to-end process of connecting brands with digital creators for sponsored content campaigns, primarily on YouTube and Meta. The company operates in the AdTech, influencer marketing, and marketing technology categories, applying large language models, automated bidding, and proprietary matching algorithms to what was previously a manual, relationship-driven process. It is venture-capital-backed and privately held.
Agentio operates a two-sided marketplace that enables brands to purchase sponsored content integrations within creator videos as programmatically as buying search or social ads [1]. The platform's core value proposition is end-to-end automation: brands define a campaign strategy and approve content, while the system handles creator matching, briefing, brand-safety review, shipping of any physical products, performance measurement, and optimization [2]. Agentio initially focused exclusively on YouTube ad reads—typically 30- to 90-second sponsor integrations embedded in long-form videos—before expanding to Meta's Instagram and Facebook through a formal integration partnership announced in July 2026 [3]. The company targets enterprise and growth-stage brand advertisers as well as individual creators, and its revenue model is a marketplace transaction fee of approximately 20% of total ad spend transacted on the platform [4]. PitchBook classifies Agentio under Business/Productivity Software with secondary verticals of AdTech, SaaS, Marketing Technology, and AI/ML [5].
Agentio was founded in 2023 by Arthur Leopold and Jonathan Meyers [1]. Leopold had previously served as president and first employee at celebrity talent marketplace Cameo, where he scaled the platform to $500 million in sales, and Meyers was a former software engineer and manager at Spotify who led that company's automated content marketing team [2]. The company launched publicly and announced a $4.25 million seed round in November 2023, co-led by Craft Ventures and AlleyCorp [3]. In November 2024, Agentio closed a $12 million Series A led by Benchmark, with participation from Craft Ventures and AlleyCorp, bringing total capital raised to $16 million at the time of that round [4]. In November 2025, the company closed a $40 million Series B led by Forerunner Ventures, with participation from Benchmark, Craft Ventures, AlleyCorp, Antler, and Starting Line, bringing total funding to $56 million at a post-money valuation of $340 million [5]. Between the Series A (November 2024) and Series B (November 2025), Agentio grew fivefold [6]. No acquisitions have been recorded as of mid-2026 [7].
Agentio operates in the influencer and creator marketing platform category, positioning itself specifically around programmatic automation of sponsored content rather than the broader influencer discovery and CRM approach taken by many incumbent platforms [1]. Forbes named Agentio to its 'Next Billion Dollar Startups, 2025' list [2]. CB Insights named Agentio a 'Highflier' alongside platforms including Later Influence, Sprout Social, and IZEA, and included the company in its Artificial Intelligence Expert Collection [3]. Notable brands documented as customers include Uber, DoorDash, CashApp, Olipop, Bombas, Mint Mobile, MasterClass, Notion, HelloFresh, Mejuri, Bilt Rewards, Vuori, The Farmer's Dog, and Warby Parker [4]. Creators associated publicly with the platform include Nick DiGiovanni, Matty Matheson, and Rhett McLaughlin and Link Neal (of Good Mythical Morning), the latter pair having joined as advisors [5]. In 2025, over 100 enterprise brands shifted tens of millions of dollars in paid media spend through Agentio's platform [6].
CB Insights places Agentio competitively alongside Later Influence, Sprout Social, and IZEA in the influencer marketing platform landscape [1]. The Unicorn Blog identifies Aspire, FameBit by YouTube, and Grapevine as direct comparators, noting that Agentio differentiates through its automation-first, programmatic approach and performance measurement capabilities rather than the manual relationship management model common to those platforms [2]. G2's alternatives page lists #paid and Insense as platforms most compared to Agentio by buyers evaluating campaign management and creator advertising capabilities [3]. Agentio's own investor AlleyCorp has compared the company's automation model to the role DoubleClick played in scaling display advertising, suggesting the primary competitive frame is 'programmatic infrastructure' versus 'managed-service influencer agency' [4]. A documented limitation relative to some competitors is Agentio's historical focus on long-form YouTube ad reads, with TikTok and Instagram Reels coverage noted by third-party reviewers as a gap being addressed through the 2026 Meta partnership and planned further platform expansion [5].
