Stephane Vaillancourt
Founder & CEO
30+ Years in Cybersecurity
With more than three decades of experience in cybersecurity and vulnerability management, Stephane has worked with global leaders including Morgan Stanley, Nomura, PayPal, the FBI, and the Bank of Canada — solving real-world security challenges across Japan, Thailand, Singapore, Hong Kong, China, the U.S., and Canada.
The Problem We Saw
Across every environment, the challenges were always the same:
Too many vulnerabilities to manage effectively
Security teams overwhelmed and under-resourced
A growing stack of tools — rarely connected or automated
"We've been looking for someone like you for eight years. We have thousands of vulnerabilities coming in daily — and we need automation."
— PayPal Security Leader
That moment helped ignite the vision for City of Hats.
Built From Scratch
After decades working with leading security platforms like Qualys, Tenable, Invicti, and Recorded Future, Stephane developed a deep understanding of how enterprise-grade vulnerability scanners and threat intelligence platforms work.
Instead of building a traditional company with high overhead, City of Hats was created as a lean, AI-powered cybersecurity studio. Personally designed from scratch:
All designed to deliver enterprise-class cybersecurity capabilities — but simpler, more efficient, and more affordable.
AI Supports Humans. It Doesn't Replace Them.
City of Hats uses advanced AI — including GPT, Claude, and proprietary security models — to continuously improve threat detection, security automation, and vulnerability analysis. But our philosophy remains grounded:
A Unified AI Cybersecurity Platform
City of Hats was built to solve the challenges security teams face every day:
Connects scanners, tools, and data sources into a single dashboard
Uses AI to identify and prioritize real-world security risks
Automates manual security workflows
Helps resolve critical vulnerabilities before they become incidents
Because sometimes, one missed vulnerability is all it takes.
Our Mission
We're not just building software. City of Hats exists to deliver AI-powered cybersecurity, vulnerability scanning, and dark web monitoring in a smarter, more scalable, and more affordable way.
"Help families and businesses stay safe in a digital world — simply, intelligently, and affordably."
Small team. Big innovation. AI-powered. Human-led.
