Bay announced a $37 million Series A led by Battery Ventures on November 10 as it emerged from stealth with software designed to stop AI agents from taking dangerous actions using legitimate access to corporate systems.
The founders say a coding agent tried to open a cloud environment to the internet while completing a test, CTech reported. The agent already had the permissions it needed; no attacker had compromised it.
Bay says it checks each proposed action against the agent’s assigned task and earlier activity, then permits it, blocks it or requests human approval. Decisions run locally in milliseconds. Its product documentation also describes a simulation mode that lets security teams test policies before applying them to employees.
The Tel Aviv startup’s disclosed funding totals $50 million, including an earlier $13 million seed round led by YL Ventures and Striker Venture Partners. Microsoft’s venture fund M12 and Wiz CEO Assaf Rappaport also participated in the Series A, Bay said.
Bay names Micron, Peloton, ClickUp and Wix among dozens of enterprise customers. Micron Ventures also participated in the Series A.
The company has about 35 employees, most in Israel, CTech reported. It plans to expand product and engineering teams and add sales, marketing and customer staff in the United States and Europe. CEO Yuval Zacharia told Calcalist she intends to relocate to the United States.
