Glow

Three founders from Meta, Snowflake and Claroty

Glow's founding team comes from three well-known tech companies, not only from the classic Israeli security market. Roy Tiger was a vice president of engineering at Meta, Omer Singer led security strategy at Snowflake, and Ophir Arie led research and development at Claroty, itself an older Israeli security company that specializes in securing operational technology. The three founded the company in 2025, and the management team was later joined by Arnon Joseph, a former senior director of product at Meta, as chief product officer, and Emily Heath, a former chief information security officer at United Airlines and DocuSign and a former partner at Cyberstarts, as chief operating officer. A lineup like this, of senior managers from giant companies who left to found a new company together, partly explains how fast they managed to raise money: investors knew their personal track record before seeing a single line of code.

The problem is not the AI itself, but what it runs on the computer

Most of the discussion about artificial intelligence security focuses on risks inside the model itself: bias, hallucinations, misuse. Glow focuses its product on a different layer: what actually happens on the work computer when an employee installs an AI tool, runs an autonomous agent or uses an AI-based browser extension. Tools like these sometimes ask for broad permissions, access sensitive files or run in the background without the employee understanding how much access they gave them. The platform tries to map all of this continuously and enforce policy before damage is done, not only detect it after the fact.

Three rounds in one year

Glow's run of funding rounds is especially compressed: a $20 million seed round led by Sequoia Capital and Cyberstarts, followed by a $60 million Series A led by Index Ventures at a valuation of $400 million, and a $100 million Series B. All of this within about a year of its founding. This pace, and not only the total of $180 million, is what stood out in the reports on its exit from stealth. Many security companies take two to three years to reach a Series B; Glow did it in less than a year, which points to unusual investor demand for the category of endpoint security in the AI era.

A valuation over a billion, before any announced customers

When it came out of stealth on 22 July 2026, a valuation of $1.2 billion was announced. It is important to notice the gap: a valuation like this, set in a private funding round, reflects what specific investors agreed to pay for a stake in the company. It is not revenue, and it does not necessarily reflect how many paying customers already use the product. The company's own announcement did not name any customers, which is typical of companies that announce the end of their stealth phase but are still at relatively early sales stages compared with the size of the announced valuation.

Tel Aviv and Palo Alto, not a single development center

Unlike cases such as Wiz, where the whole development center is in Israel, Glow has two main offices, in Tel Aviv and in Palo Alto, California, and no exact breakdown of staff between them has been published. The company is considered Israeli mainly because of its founders and the location of one of its main offices, similar to a pattern that repeats in many Israeli cybersecurity companies that target the American market from the start.
