Pluto Security has raised $42 million to help companies monitor and control how employees use AI tools, the startup announced as it emerged from stealth. The funding comprises an $8.5 million seed round led by TLV Partners, with cybersecurity firm Armis' founders also investing, and a $34 million Series A led by Jump Capital, with Skinos, Ansa Capital and other angel investors participating.
Shahar Bahat, CEO and co-founder of Pluto Security, said a newly announced AI tool can show up inside companies' environments within two hours of its release. About 60% of the risks her company detects across its customer base are in tools vibe-coded by non-developers, she told TechCrunch, with finance departments the biggest source, followed by marketing and legal teams. Developers rank fourth.
Pluto's software monitors the AI tools employees use, the skills, extensions and MCP servers those tools rely on, as well as the apps and agents being created. The company says it can identify risky components, spot potentially dangerous agent activity, and enforce security policies without stopping employees from using or making AI tools. Bahat said the system can intervene while an agent is working, for example stopping an action or adding instructions into the session that prompt the agent to ask for confirmation.
Bahat said Pluto began selling in April and has already crossed $2 million in annual recurring revenue, with more than 30 enterprise customers including Oscar Health, Workato, Sixt and AlphaSense. She said 70% of the company's sales pipeline now comes from inbound interest.
Pluto said it plans to invest the new capital in developing its product, expanding its security research efforts, and growing its presence in the U.S. It has 40 employees in the U.S. and Israel.
