Summary
$42 million in new funding brings Pluto Security out of stealth as it targets enterprise risks from employee-built and employee-used AI tools.
Just six months after starting sales in April, Pluto says it has topped $2 million in annual recurring revenue and signed more than 30 enterprise customers, including Oscar Health, Workato, Sixt and AlphaSense.
60% of the risks Pluto detects come from vibe-coded tools built by non-developers, with finance teams the biggest source; Bahat said the company found threats in every proof of concept and sometimes live attacks.
Pluto’s software monitors AI tools, agents, extensions and MCP servers in real time, then can block actions or prompt for confirmation if an agent seeks permissions beyond a user’s intent.
The round includes an $8.5 million seed led by TLV Partners and a $34 million Series A led by Jump Capital; Pluto plans to use the money for product development, security research and U.S. expansion.
