Ex-Google Security Leaders Launch AegisAI With $13 Million to Reinvent Email Defense

The startup deploys orchestrated AI agents to reason over messages and block phishing before delivery as attackers adopt more convincing LLM-generated lures.

Overview

  • AegisAI emerged from stealth with a $13 million seed round co-led by Accel and Foundation Capital, founded by former Google Safe Browsing and reCAPTCHA leads Cy Khormaee and Ryan Luo.
  • The platform uses a coordinated network of specialized LLM-based agents that analyze links, attachments, metadata, QR codes, and behavioral signals to deliver real-time threat verdicts without static rules.
  • The company is running pilots in the U.S. and Europe, has three paying customers including Lokker and Mesh Connect, and integrates via API with Google Workspace and Microsoft 365.
  • AegisAI says its system identifies malicious emails roughly 20% better than conventional tools and reduces false positives by up to 90%, claims that have not been independently verified.
  • Industry data underscores the urgency as CISA attributes over 90% of successful cyberattacks to phishing and CrowdStrike reports LLM-generated phishing saw a 54% click-through rate in 2024 versus 12% for human-written emails.
