Bay announced on 10 November 2026 that it is leaving stealth with $50 million raised across two rounds, according to its launch release, which is datelined Tel Aviv, and to reports by SiliconANGLE and Globes. The $37 million Series A was led by Battery Ventures. The $13 million seed round, which had not been disclosed before, was co-led by YL Ventures and Striker Venture Partners. The release names Micron Ventures, M12 (Microsoft’s venture fund) and Assaf Rappaport, CEO of Wiz, among Series A participants; SiliconANGLE says Rappaport invested personally. The valuation was not disclosed.

What Bay does

Bay sells a security platform for AI agents. Its website calls it “the single control plane for all agentic activity”. The release says it provides governance and enforcement across devices, cloud and SaaS applications, can be deployed in under five minutes without a persistent endpoint agent, kernel driver or network proxy, and makes decisions locally in milliseconds. SiliconANGLE describes a component called Wave that inventories agents, extensions and local models on each machine, an enforcement component that checks each proposed action with full session context and returns allow, ask the user or block, and a component called Lighthouse that drafts policies for each team from the previous 30 days of agent activity. Bay’s website and an AWS Marketplace listing put the decision time at under 4 milliseconds.

Company and funds

The founders are Yuval Zacharia, co-founder and CEO; Aner Morag, co-founder and chief product officer; and Boris Danilovich, co-founder and vice president of R&D. Globes reports 35 employees, most in Israel, and says the company was founded in early 2026; SiliconANGLE says about nine months before launch. The release says the money will expand product and engineering teams and grow sales, marketing and customer teams in the US and Europe. Zacharia said in the release: “Either way, the challenge is the same: enabling AI adoption at scale without losing control.”

Company claims

The following claims are the company’s and have not been independently verified. Bay says it has signed dozens of enterprise customers in about nine months and names Micron, Peloton, ClickUp and Wix; the release headline says Fortune 100 companies used its platform to triple their use of autonomous AI agents, without identifying those companies or quantifying the increase. SiliconANGLE reports a false-positive rate under 1% “per the company”; that figure is not in Bay’s release. BankInfoSecurity reports that Bay was deployed across 150,000 Micron endpoints in under five minutes; other outlets do not report that figure.

Sources and notes

Sources: Bay’s launch release and a founder post by Yuval Zacharia on bay.io (both 10 November 2026), SiliconANGLE (Duncan Riley), Globes (Meytal Vaizberg), BankInfoSecurity (Michael Novinson), EconoTimes, the TechStartups report of 10 November and an MLQ summary. Lens did not find the original wire release. BankInfoSecurity describes the whole $50 million as the Series A, whereas the company and the other outlets split it into $37 million and $13 million. The product name “Bay Enforcer” appears in SiliconANGLE and the AWS listing but not in the company’s release or founder post. The company is called Bay, Bay AI, Inc. and Bay Security in different places.
