Agentio is an AI-native advertising platform that automates creator-led campaigns across YouTube and Instagram, compressing multi-month influencer workflows into minutes. Rather than a SaaS tool or agency, Agentio positions itself as infrastructure that handles AI-powered creator matching based on performance data, pricing, contracts, shipping, content review, full-funnel measurement with conversion attribution, and invoicing. Founded in 2023 by CEO Arthur Leopold (former president at Cameo) and CTO Jonathan Meyers (former Spotify engineer), Agentio works with brands including Uber, DoorDash, Skims, Warby Parker, Tecovas, CashApp and Olipop, which have shifted tens of millions in paid media to creator campaigns on the platform. Each campaign generates first-party signals that improve future targeting. Agentio raised an $18M Series A led by Benchmark in 2024 and a $40M Series B led by Forerunner Ventures in November 2025, bringing total funding to $56M at a $340M valuation.
