Pluto Security raises $42M to secure enterprise AI tool usage
Pluto Security emerged from stealth on Monday with $42 million in total funding to help enterprises monitor and control how employees use AI tools. The startup says it began selling in April and has reached $2 million in annual recurring revenue with more than 30 enterprise customers including Oscar Health, Workato, Sixt and AlphaSense.
Key points
- Pluto Security raises $42M total ($8.5M seed, $34M Series A) for enterprise AI security
- Startup detects 60% of risks from non-developer 'vibe-coded' apps, led by finance teams
- Reached $2M ARR with 30+ enterprise customers since April launch
CEO Shahar Bahat told TechCrunch that new AI tools can appear in corporate environments within two hours of release, and about 60% of risks Pluto detects come from "vibe-coded" applications built by non-developers, led by finance departments. The company's software monitors AI tools, skills, extensions, MCP servers and agents in real time, connecting to endpoint security systems and using lightweight models on devices to assess agent behavior. Pluto can intervene during agent sessions, such as stopping unauthorized permission requests or injecting confirmation prompts.
Funding includes an $8.5 million seed round led by TLV Partners and a $34 million Series A led by Jump Capital, with participation from Skinos, Ansa Capital and angel investors. Pluto also operates Plutonium, a free platform for checking risks in public AI skills and connectors, which Bahat says drives 70% of the sales pipeline. The company plans to use the capital for product development, security research and U.S. expansion across its 40-person team in the U.S. and Israel.
