Zenity closed a $125 million Series C led by Norwest, with SoftBank Vision Fund 2, Qumra Capital, Hitachi Ventures, and LG Technology Ventures joining alongside existing backers. The New York and Tel Aviv company builds security for autonomous AI agents across Copilot, ChatGPT Enterprise, Gemini, Claude, Cursor, and custom stacks, aiming to allow, modify, or block actions from agent intent rather than prompt scanning alone. Zenity says it has tripled revenue two years running and serves many Fortune 500 customers. Why it matters: investors are funding runtime guardrails as agents go live. Caveat: growth claims and category praise come from the company's own announcement.
