Bay, the AI security platform building the trust layer for agentic enterprises, today emerged from stealth less than a year after its founding with dozens of enterprise customers, including Micron, Peloton, ClickUp and Wix. Bay addresses a primary barrier to AI adoption by allowing autonomous agents to perform business-critical work safely while enterprises retain control and accountability at scale.

Bay Emerges from Stealth with $50M After Fortune 100 Companies Used Its Platform to Triple Autonomous AI Agent Use

Bay Emerges from Stealth with $50M After Fortune 100 Companies Used Its Platform to Triple Autonomous AI Agent Use

Bay has raised $50 million in total funding. The financing includes a $37 million Series A led by Battery Ventures and a previously undisclosed $13 million seed led by YL Ventures and Striker Venture Partners. Micron Ventures, M12, Microsoft’s Venture Fund and Assaf Rappaport, CEO of Wiz, also participated in the Series A.

“AI is fundamentally changing how enterprises operate, and the ability to deploy autonomous agents safely will become a critical competitive advantage,” said Andrew Byrnes, Director of Venture Capital, Micron. “We’ve seen firsthand how Bay’s technology can help accelerate AI adoption while maintaining the control and accountability required in a large enterprise. We believe that this trust layer will become essential infrastructure for the agentic era.”

Bay grew out of the same problem it now solves for customers. Its founders watched one of their coding agents try to expose a cloud environment to the internet to complete a test. The agent had not been compromised. It used legitimate permissions to pursue a legitimate goal in a dangerous way.

Bay brings AI governance and enforcement across employee devices, cloud infrastructure, and SaaS applications in under 5 minutes, without an additional persistent endpoint agent, kernel driver, or network proxy. It secures the full range of AI that enterprises are deploying through a single platform that covers multiple use cases under one set of policies. Bay combines AI discovery and posture management, session-level observability, and real-time enforcement, and connects to existing security workflows for automated remediation.

“In Bay, we saw a company we felt had a differentiated technical approach that was already winning enterprise customers at an early stage,” said Dharmesh Thakker, General Partner at Battery Ventures. “That combination gave us conviction to lead the round. We believe Bay can become a core control layer for companies putting AI agents to work at scale.”

“We evaluated a crowded field of companies addressing AI agent security, and Bay stood out because it can understand and control individual agent actions, from the endpoint to the cloud, while fitting into infrastructure enterprises already use,” said Yoav Leitersdorf, managing partner at YL Ventures. “We believe Bay can become as fundamental to enterprise AI adoption as the network firewall was to the internet era.”

Bay evaluates each proposed action in the context of the full agent session and decides locally in milliseconds whether it can proceed. Instead of requiring security teams to write and maintain rules for every new agent or tool, Bay learns from the organization’s agent activity and interprets context around each action in real time, distinguishing between activity that looks identical in isolation but carries very different risks. As teams add new agents and workflows, Bay adapts its policies and expands the work agents can safely do on their own. The platform works across the AI models, assistants, and agent frameworks an organization chooses.

“If you’re a security leader at an enterprise today, you’re likely facing one of two realities: either AI agents have already spread across your organization and it’s the Wild West, or your leadership has mandated an enterprise-wide AI rollout by the end of the year to accelerate the business,” said Yuval Zacharia, co-founder and CEO of Bay. “Either way, the challenge is the same: enabling AI adoption at scale without losing control. 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.”

Zacharia founded Bay alongside CPO Aner Morag and VP of R&D Boris Danilovich. Zacharia began her career in Israeli intelligence at Unit 8200, where she led a department of 50 people before becoming the first-ever intelligence officer to transition into offensive cybersecurity and was assigned to the unit’s most elite department. Following her military service, she served as Director of Research and AI at Hunters.

Danilovich previously led a department of 90 engineers at CrowdStrike, spearheading one of the most critical components of its endpoint security platform and serving as a key leader of the company’s Israeli R&D center. Morag joined Noname Security as one of its earliest employees, rising to VP of Product and playing a key role in scaling the company.

Bay is available to enterprises today. The company will use the funding to expand its product and engineering teams and grow its sales, marketing, and customer teams in the United States and Europe.
