Infisical raises $40M Series B at $600M valuation led by Elad Gil

The company was already profitable and didn't need the cash, but raised anyway to get ahead of AI agents accessing sensitive systems.

• Infisical raised $40 million in Series B funding at a $600 million valuation, led by Elad Gil, who also led its Series A.
• The San Francisco company builds infrastructure for managing secrets, encryption keys, and digital certificates, and for privileged access across cloud, on-prem, and AI systems; customers include Airbus, Volkswagen, Hugging Face, and Wise.
• Its new Agent Vault lets AI agents reach approved systems through a proxy that injects real credentials on the agent's behalf, so the agent only ever handles placeholders, not actual passwords or API keys.
• Infisical now serves over 1,300 organizations and 300,000 developers, secures 10 billion secrets daily, and its open-source project has topped 30,000 GitHub stars.
• The Series B is a major step up from Infisical's $16 million Series A in June 2025, also led by Elad Gil, bringing total funding to nearly $60 million.
• The raise lands amid a broader surge in funding for AI-agent identity security, including Oak's $60 million and NewCore's $66 million raises, as cybersecurity funding hit $6.8 billion in Q3 2026.
• As AI agents gain direct access to enterprise systems, securing machine identities rather than just human credentials is becoming a foundational cybersecurity category.
