San Francisco-based JetStream Security has emerged from stealth with a $34 million seed round and the launch of its enterprise AI governance platform. The heavily oversubscribed round was led by Redpoint Ventures, with participation from the CrowdStrike Falcon Fund. Prominent angel investors include George Kurtz, Assaf Rappaport, and Frederic Kerrest.
The company was founded by veteran security leaders from CrowdStrike, Dazz, SentinelOne, Cohesity, McAfee, and Attivo Networks. CEO Raj Rajamani, former Chief Product Officer at CrowdStrike, and co-founder Jared Phipps, formerly of SentinelOne, are spearheading the effort.
JetStream aims to address what it calls the enterprise AI “trust deficit.” As organizations deploy autonomous agents and local Model Context Protocol (MCP) servers, visibility and control often lag. AI systems can behave unpredictably, access unauthorized data, and generate runaway token costs.
Its core innovation, AI Blueprint™, creates real-time operational maps of agents, models, data access, and user identities. The platform detects deviations from approved workflows, governs MCP integrations, and provides token-level financial visibility—combining security and FinOps in a single interface.
Already working with Fortune 500 companies, JetStream positions itself as a unified governance layer for securing hybrid AI environments at scale.
