Our Story
As defenders, we know firsthand what it takes to investigate an attack and protect an organization. We’ve spent our careers in security and have followed closely how attacks are evolving as adversaries adopt agentic AI to automate more of their operations.
We founded Mesa around a shared conviction: security teams need agents working alongside them. We’re building Mesa to put our expertise in AI and threat research to work through specialist agents that understand the organization they protect, investigate threats, and help carry out the response, with the security team in control.

Chief Executive Officer
Hello, thanks for stopping by.
Millions of organizations now increasingly face the same sophisticated cyberthreats as Fortune 500 companies, often with no security teams to defend them. These include your local nonprofits, schools, religious organizations, credit unions, and many more. We’re building Mesa to help close that gap by harnessing the power of AI to bring security expertise and practical support to the people protecting such organizations.
Before Mesa, I co-founded Bolster AI and served as its CTO. I helped grow the company from its earliest days through Series B, with funding from investors including Microsoft’s M12 venture fund. There, I built AI-powered systems to detect and take down phishing and fraudulent websites for Fortune 500 companies.
Along the way, I’ve become a named inventor on six U.S. patents, including real-time detection and blocking of counterfeit websites and automated takedown.
If you’re exploring Mesa or have a security challenge on your mind, I’d love to hear from you. Reach us through our Contact Us page.
