Exaforce Raises $125 Million Series B at $725 Million Valuation for AI-Native Security Operations
Tags AI · Enterprise · Infrastructure
Exaforce raised $125 million in Series B funding at a reported $725 million valuation, just one year after its $75 million Series A, bringing total funding to $200 million. The round was led by HarbourVest, Peak XV, Mayfield, Khosla Ventures, and Seligman Ventures. The three-year-old San Francisco Bay Area startup uses AI agents called 'Exabots' with a real-time security knowledge graph to automate security operations, reducing manual tasks by up to 90% and answering investigative questions in under a minute. The company recently introduced 'vibe hunting,' allowing security teams to query the platform with natural language. Exaforce has 20 customers including Replit and Guardant Health, targeting 40-50 by end of 2026.
Technical significance
Exaforce's rapid follow-on (12 months after Series A) at a near-$1B valuation reflects the market's conviction that AI-native SOC platforms will replace traditional SIEM/SOAR stacks. The 90% manual task reduction claim, if validated at scale, would fundamentally change the economics of security operations. The 'vibe hunting' feature — natural language queries for threat investigation — represents a paradigm shift from query-language-dependent security tools.
