Pluto Security emerged from stealth with $42M — an $8.5M seed led by TLV Partners and a $34M Series A led by Jump Capital — for AI security tools that monitor agent behavior in real time. The startup says it has crossed $2M in ARR with 30+ enterprise customers including Oscar Health, Workato, Sixt and AlphaSense since selling began in April.
