Israeli Startup Bay Raises $50 Million to Control AI Agent Actions
Tel Aviv based Bay emerged from stealth on November 10 with $50 million in total funding and a platform designed to stop dangerous AI agent actions before they run. The financing combines a new $37 million Series A with a previously undisclosed $13 million seed round.
Battery Ventures led the Series A, joined by Micron Ventures, Microsoft's M12 venture fund and Wiz chief executive Assaf Rappaport, Bay said. YL Ventures and Striker led the earlier seed investment. The company was founded in 2026 and says it already serves dozens of enterprise customers, including Micron, Peloton, ClickUp and Wix.
A Coding Agent Prompted the Idea
Chief executive Yuval Zacharia described the company's starting point in a launch post: the founders were testing a different business idea when a coding agent tried to open their cloud environment to the public internet to finish its task. It was using permissions the team had given it.
The founders saw a security problem in an authorized tool choosing an unsafe route to an ordinary objective. Their response was to build software that examines what an agent is about to do in the context of the work it has been assigned.
That places Bay within the growing field of AI security, where the object being supervised can act on a company's systems, rather than simply produce a written answer.
Checking the Action Before It Runs
Bay's product documentation describes an assessment of the full agent session. Depending on company policy and the action's context, the software can permit an action, request approval, deny it or redirect the agent. Bay says decisions are made locally on the device in milliseconds.
The distinction is practical: reading a file, changing a cloud setting and sending information elsewhere each have consequences beyond the conversation window. An organization granting an agent access still needs to control how that access is used during a particular task.
The platform also offers policy simulations, allowing security teams to examine what proposed rules would permit or stop before applying them to employees. Its Lighthouse component uses 30 days of agent activity to help develop policies for individual teams, according to the company.
Customers Span Software and Manufacturing
Micron appears in the announcement as both a customer and an investor through Micron Ventures. The named customer list also spans workplace software, website building and connected fitness, showing the range of businesses Bay is targeting.
The company markets coverage across employee devices, cloud infrastructure and software services. Bay's central commercial proposition is that organizations can give agents more useful work while retaining the ability to intervene at the point of action.
Tel Aviv Team Plans Expansion
Zacharia founded Bay with chief product officer Aner Morag and research and development vice president Boris Danilovich. Her previous roles included leading research and AI at Hunters. Morag worked at Noname Security, while Danilovich held engineering leadership roles at CrowdStrike.
Bay joins an Israeli cybersecurity sector selling products to international enterprises. The company says the new capital will expand product development and engineering, as well as sales, marketing and customer teams in the United States and Europe. Its headquarters are in Tel Aviv, and the platform is now commercially available to enterprises.
