Ryan Luo

Ryan Luo is Co-Founder and CTO at AegisAI, an AI-native email security platform using autonomous agents to eliminate phishing, malware, and Business Email Compromise attacks before they reach user inboxes.
Ryan spent nine years at Google protecting users at internet scale, modernizing the core Safe Browsing phishing platform and building reCAPTCHA's product-led growth strategy, driving its adoption by millions of sites worldwide. He studied at Pomona College, graduating in 2016, and is a Yale Computer Science Award recipient.
Ryan believes in creating better security outcomes rather than more alerts, applying his deep adversarial threat expertise to architect AI systems that think like human analysts. His philosophy centers on eliminating operational burden for security teams while delivering reliable, adaptive intelligence.
At Google, Ryan spent nearly a decade on the Safe Browsing and reCAPTCHA teams, helping protect billions of users from phishing, malware, and fraud at internet scale. He also organized Google's 5C Hackathon, reflecting his passion for solving complex problems through collaboration and innovation.
AegisAI launched in September 2025 with a $13M seed round led by Accel and Foundation Capital, and its platform reduces false positives by up to 90% compared to traditional email security solutions. The company integrates seamlessly with Microsoft 365 and Google Workspace, with AI agents continuously learning from real-world adversarial behavior to protect enterprises at scale.
