AegisAI Raises $36M to Fight AI Spear Phishing
AegisAI, founded by former Google security executives Cy Khormaee and Ryan Luo, has raised $36 million in a Series A led by Battery Ventures to defend against AI-driven spear phishing. The startup uses AI agents to analyze incoming emails for subtle anomalies that rule-based systems miss. Less than a year after launch, AegisAI reports adoption by dozens of customers, including Mesh, LangChain, and Lokker, and has now raised a total of $49 million in capital. Investors Accel and Foundation Capital participated in the round. The company plans to expand beyond email into broader areas of defense such as data security. The funding reflects investor interest in AI-driven defensive tools as email attacks increasingly leverage generative AI.
AegisAI’s Series A and early customer traction indicate growing investor and market interest in AI-driven email security as AI-enabled spear phishing rises; relevant to companies relying on email channels but not industry-shifting for AdTech broadly.
