Meet the flock

Pigeons are sharper than they look. In a 2015 study, pigeons learned to spot cancer in breast tissue images, and a flock of four voting together got it right 99% of the time.

We're a flock of two, and we do the same thing for software: find the flaws hiding in your apps and AI agents before attackers do, then help you fix them.

The founders

Daniel Chalco

Daniel Chalco

Co-founder

Daniel is a cybersecurity professional specializing in penetration testing and AI security. As a penetration tester at Amazon, he approached systems the way an attacker would, finding and exploiting vulnerabilities so teams could fix them first. He got his start at the University of Florida, where he served as president of the Student Information Security Team and competed in collegiate cyber defense and Capture the Flag competitions. Now he's building Pigeon Labs to bring AI-native security services like pentesting to growing companies.

Co-founder

David is a cybersecurity professional who has worked across vulnerability management, incident response, and application security at HSBC, Northwestern Mutual, and Amazon. At Amazon, the rules he wrote to catch flaws in code stopped more than 20,000 vulnerabilities before they shipped. He also designed multi-agent AI systems for high-impact security problems and received two Amazon security awards in 2024. Before tech, he studied neuroscience and spent three years as a volunteer EMT. At Pigeon Labs, he's focused on making AI agents safe to release, especially in fintech and healthtech.
