Bay Raises $37M Series A to Scale Enterprise AI Agent Security

What happened
Bay, a startup based in Tel Aviv, announced on November 10, 2026, that it raised $37 million in Series A funding led by Battery Ventures. The company emerged from stealth with a platform that controls the actions of enterprise AI agents by evaluating the safety of each action in real time. The platform is already being used by several enterprises, including Micron and Peloton. Bay plans to use the new funding to expand its teams and operations in the United States and Europe.
Key details
- Bay has raised a total of $50 million, combining the new Series A with a previous $13 million seed round.
- Investors in the Series A include Battery Ventures, Micron Ventures, Microsoft’s M12, and Wiz CEO Assaf Rappaport.
- The platform assesses the safety of AI agent actions based on real-time session context, not just permissions.
- Deployment reportedly takes under five minutes and does not require persistent endpoint agents or network proxies.
- Bay's founding team includes Yuval Zacharia, Aner Morag, and Boris Danilovich, with backgrounds in cybersecurity and AI.
Why it matters
Large organizations using AI agents now have access to a tool that can enforce security policies in real time, reducing the risk of unsafe actions by authorized agents. Enterprises adopting Bay's platform may be able to increase their use of autonomous AI agents while maintaining control and accountability. The funding enables Bay to offer its solution to more companies in the US and Europe, potentially impacting how businesses manage AI security at scale.
