Reco Raises $55M Series C With AT&T Strategic to Extend Agentic AI Security to Rogue Agents

Israeli AI-security startup Reco raised a $55M Series C led by AT&T Ventures, Forestay and Quadrille Capital, taking total funding to $140M at a valuation Reco says has more than doubled since its February Series B. The pitch has shifted from SaaS posture to a context graph that maps every agent to the apps, accounts and permissions it can touch — Reco says one Fortune 100 customer discovered 21,000 previously unknown agents on deployment. ARR is in the double-digit millions and expected to triple in 2026.
