AegisAI, the year-old email-security startup founded by former Google safe-browsing and reCAPTCHA leads Cy Khormaee and Ryan Luo, closed a $36 million Series A on July 23, 2026 led by Battery Ventures. Existing backers Accel and Foundation Capital re-upped, bringing AegisAI’s total funding to $49 million less than a year after emerging from stealth.
Agentic Defense Against AI-Crafted Phishing
AegisAI deploys autonomous agents that read every incoming message the way a human would, catching AI-generated spear phishing that rule-based “if-then” filters miss. The company’s pitch is that AI-written attacks now bypass legacy controls more than half the time, so defenders need an AI counterparty rather than another rule set. Early customers include enterprise AI framework maker LangChain, crypto payments company Mash and Google-owned privacy platform Lokker.
Vanguard And The Data-Security Roadmap
The fresh capital funds general availability for Vanguard, AegisAI’s agent for hunting threats that already made it past the inbox, plus enterprise go-to-market and a longer roadmap toward broader data security. General partner Dharmesh Thakker of Battery told TechCrunch that Khormaee’s and Luo’s Gmail pedigree gave AegisAI the best odds to unseat entrenched vendors such as Proofpoint, Mimecast and Abnormal Security.
Where AegisAI Fits In A Widening Anti-Phishing Race
Lightspeed-backed Ocean announced a $28 million round earlier this year for a similar agentic anti-phishing product, and this week’s round arrives against a backdrop of ever-more-sophisticated ransomware traffic — including a Chaos ransomware browser-tunneled backdoor disclosed on the same day and ReliaQuest’s new agentic-defense tie-up with OpenAI. Khormaee described the endgame plainly: “The core idea of building customized, highly advanced agents that can do investigations is going to determine who becomes the next dominant security company.”
