Israeli AI Security Startup Bay Raises $50 Million

Israeli cybersecurity startup Bay, which has developed a platform to prevent risky actions by AI agents within organizations, has announced a total funding of $50 million within nine months of its establishment. The funding includes a $37 million Series A round led by Battery Ventures, with participation from Micron Ventures, the investment arm of chip manufacturer Micron, which is also a customer of Bay. This round follows a $13 million seed round led by YL Ventures and Striker.

Notable private investors in Bay include Assaf Rappaport, CEO of Wiz; Gito Patel, CPO at Cisco; and Manuj Apta, former CSO at Zscaler. The company was founded in early 2026 by CEO Yuval Zakharya, VP of Product Anar Morag, and VP of R&D Boris Danilovich. Zakharya, a former intelligence officer in Unit 8200 with experience in offensive cyber, previously led AI development at Hunters. Morag also transitioned from intelligence to offensive cyber in Unit 8200 and was an early employee at Noname Security, where he led R&D and product departments. Danilovich was an early employee at Preempt Security, acquired by CrowdStrike, where he managed a large engineering team.

Bay currently employs approximately 35 people, most of whom are based in Israel. Zakharya stated that the rapid fundraising was significantly driven by the company's numerous customers and the substantial revenue generated in a short period. She highlighted the product's technological uniqueness, ease of installation, and immediate value proposition for clients, enabling widespread adoption across organizations.

The platform is designed to monitor and control autonomous AI agents, preventing them from performing harmful actions, whether malicious or unintentional. Bay serves dozens of organizations globally across finance, insurance, technology, industry, and media, including Wix, ClickUp, Micron, and Peloton. Some Fortune 100 clients have reportedly tripled their use of autonomous AI agents while maintaining security standards.

Bay's technology analyzes AI agent actions in real-time, distinguishing between risky and safe operations based on context and predefined security policies. The system can allow, block, or flag actions for human approval within milliseconds. The platform integrates seamlessly with existing security tools, deploying in under five minutes without requiring additional monitoring software. It supports various AI agents and enforces uniform security policies across cloud, SaaS, and endpoint environments using proprietary, patent-pending technology.
