Pluto Security, an Israeli startup, exited stealth on October 13, 2026 with $42M in seed and Series A funding to secure the AI tools and agents employees build themselves.
Key Takeaways
- Pluto Security raised $42M: an $8.5M seed led by TLV Partners and a $34M Series A led by Jump Capital.
- The company says it has 40+ enterprise customers and 1M+ endpoints secured, less than a year after its 2025 founding.
- Valuation was not disclosed.
Lead
Pluto Security, a cybersecurity startup with operations in Israel and the United States, came out of stealth on October 13, 2026 with $42M in total funding. The round combines an $8.5M seed led by TLV Partners and a roughly $34M Series A led by Jump Capital. The company sells a platform that gives security teams visibility into, and control over, the AI tools employees use and the applications and agents they assemble with them. It was founded in 2025.
Who Backed the Round and What Was Not Disclosed
Jump Capital led the Series A. Skinos Ventures, the fund associated with Shlomo Kramer, and AlphaDrive Ventures joined that round. TLV Partners led the earlier seed, with Ansa Capital also participating, according to the company's announcement.
Pluto did not disclose a valuation. The 4-to-1 ratio between the Series A and the seed is large for a company less than a year old, and it suggests investors priced the round on early commercial traction rather than on product promise. Pluto says it began selling in 2026 and has reached annual recurring revenue in the low millions of dollars; one account puts it at $2M+ since sales began in April. The company has not published an exact figure.
What Does Pluto Security Actually Sell?
Pluto sells a control layer for what the industry calls shadow AI: chatbots, coding assistants, browser extensions, plugins and agents that employees adopt or build without a security review. The platform maps these tools and their supply chain components, scores their risk in context, and enforces policy in real time. The aim is to let staff keep building while security teams block only what is dangerous.
CEO Shahar Bahat framed the problem in the company's announcement: "Security has traditionally been built around stopping things, but that model breaks down when business moves faster than security can evaluate every new tool." Bahat is a former senior cybersecurity leader at Microsoft and a veteran of IDF Unit 8200. Chief Product Officer Tal Ofer Regev previously served as VP of R&D at Palo Alto Networks. CTO Gil Maman spent more than six years in Israeli military intelligence.
The product competes for budget with established endpoint, browser-security and data-loss-prevention vendors, which are adding AI controls of their own. It also faces a crowd of AI-security startups that have raised funding in the past two years. Pluto's pitch is that employee-built applications, not just employee use of third-party chatbots, are the harder surface to govern.
How Large Is Pluto's Customer Base?
Pluto reports more than 40 enterprise customers, including Oscar Health, Workato, Sixt and AlphaSense, plus Fortune 500 organizations. It says its software covers more than 1 million endpoints globally. Headcount stands at 40 to 50-plus across Israel and the U.S., depending on the account.
Those figures come from the company and have not been independently verified. Endpoint counts in particular measure deployment reach, not revenue, and large enterprise rollouts often begin as pilots covering a fraction of staff. The customer count also varies between published accounts, with some citing 30+ and others 40+.
What Is Plutonium?
Plutonium is a free AI risk database that Pluto built on its proprietary RisksDB and opened to practitioners. It lets security professionals assess components such as AI skills and extensions, and hundreds of them use or contribute to it weekly, according to the company. Jump Capital partner Saaya Pal pointed to it as the clearest example of the team's approach, noting there was little good public data on what AI tools actually do inside enterprises.
The database serves two purposes. It builds goodwill among security teams who are the product's buyers, and it feeds Pluto's detection research. A community-first strategy of this kind has worked for other security vendors that turned open resources into enterprise pipelines.
What Comes Next for Pluto?
Pluto plans to spend the new capital on product development, security research and expansion of its U.S. presence. Its customer list already skews American, and Jump Capital's involvement adds a U.S.-based lead investor to a cap table that began with an Israeli seed fund.
The main test is retention. Customers who bought quickly in a year of intense AI anxiety will decide whether employee-built AI governance stays a standalone category or folds into larger security platforms. Incumbents have both the distribution and the incentive to bundle similar controls.
Outlook
Pluto Security enters the market with $42M, a founder team drawn from Microsoft, Palo Alto Networks and Israeli intelligence units, and a customer list that includes recognizable names. Revenue in the low millions is respectable for a company that began selling in April, though it leaves open how much of the Series A reflects demonstrated demand and how much reflects investor appetite for AI security. The next 12 months of customer expansion, and any acquisition interest from larger vendors, will show which.
