Israeli cybersecurity startup Bay emerged from stealth on Nov. 10 with $50 million in total funding, seeking to limit security risks from autonomous AI agents operating with legitimate corporate access.
Bay disclosed a $37 million Series A led by Battery Ventures and an earlier, previously undisclosed $13 million seed round led by YL Ventures and Striker Venture Partners. The two rounds together account for the $50 million total.
Micron Ventures; M12, Microsoft’s venture fund; and Wiz CEO Assaf Rappaport also joined the Series A. Battery Ventures General Partner Dharmesh Thakker cited Bay’s technology and its early enterprise customers in explaining the firm’s decision to lead the round.
Bay says its software weighs an agent’s proposed action against its earlier activity before deciding whether the action can proceed. The company says its controls work on employee devices, in cloud infrastructure and in software-as-a-service applications.
The risk can arise without an attacker taking control of an agent. Bay says its founders saw one of their coding agents attempt to make a cloud environment reachable from the internet while completing a test. The agent had legitimate permissions and had not been compromised, according to the company.
Bay identifies Micron, Peloton, ClickUp and Wix among what it says are dozens of enterprise customers. Bay CEO Yuval Zacharia said the company’s aim is to help businesses use AI agents more widely while retaining control over their actions.
Bay plans to increase its product and engineering headcount and add to sales, marketing and customer teams based in the United States and Europe. It did not give hiring targets or a timetable for that expansion.
