Bay, a Tel Aviv startup building security for enterprise AI agents, has emerged from stealth with $50 million in total funding. The company announced the financing on November 10, less than a year after its founding.
Bay sells a platform that acts as a trust layer for companies letting autonomous agents do business critical work. It checks what agents are about to do before they do it, so enterprises can widen agent use without losing control.
The funding breakdown
The total combines a $37 million Series A led by Battery Ventures with a previously undisclosed $13 million seed round led by YL Ventures and Striker Venture Partners. Micron Ventures, M12, the venture fund of Microsoft, and Assaf Rappaport, the chief executive of Wiz, also joined the Series A.
Bay was founded nine months ago and already counts dozens of enterprise customers. The company says Fortune 100 customers used its platform to triple their use of autonomous AI agents.
What Bay does
The platform governs AI agents across employee devices, cloud infrastructure and software applications. It deploys in under five minutes, with no persistent endpoint agent, kernel driver or network proxy to install.
Bay combines agent discovery, posture management, session level observability and real time enforcement in one system. It evaluates each proposed action in the context of the full agent session and decides locally in milliseconds whether it can proceed.
Instead of asking security teams to write rules for every new agent or tool, Bay learns from the agent activity inside an organisation and adapts its policies as teams add new agents and workflows.
Why enterprises are paying attention
The problem Bay solves came from its own founders. They watched one of their coding agents try to expose a cloud environment to the internet in order to complete a test. The agent had not been compromised. It used legitimate permissions to pursue a legitimate goal in a dangerous way.
Bay says its named customers include Micron, Peloton, ClickUp and Wix. The company is available to enterprises today and plans to use the funding to expand its product and engineering teams and grow its sales, marketing and customer teams in the United States and Europe.
The team behind it
Bay was founded by Yuval Zacharia, its chief executive, Boris Danilovich, its vice president of research and development, and Aner Morag, its chief product officer. Zacharia previously led a department of 50 people in Israeli intelligence unit 8200 and later served as director of research and AI at Hunters.
Danilovich previously led a department of 90 engineers at CrowdStrike, while Morag was one of the earliest employees at Noname Security and rose to vice president of product.
Bay was built to be the one platform that secures every way the enterprise uses AI, so security becomes the reason AI ships faster, not the reason it stalls.

What happens next
Bay will spend the new money on hiring and on reaching more enterprise buyers in the United States and Europe. The company argues that control at the execution layer, not just visibility into agent activity, is what will let enterprises move from AI experiments to wide deployment.
