Sam is the youngest guest to join the show so far, having started his company Kasada while he was still a teenager. After experience working in the Australian Signals Directorate (ASD) in high school, basically the NSA of Australia, Sam decided to forgo college ("university" for the Australians) in favor of going directly into the security world. Shortly after, he founded Kasada, which is built around a bot deterrence platform that presents complex quantitative challenges that cost attackers thousands in compute resources. Kasada has seen explosive growth, as it received funding from the CIA's venture group in its 2019 Series A, received a Series B in 2020, and now has over 50 employees.
