Tim Tickel spent years as a security engineer at companies like Google, Facebook, Uber, Reddit, Plaid, and BitMEX, working on things like authentication, access controls, and protecting user data at huge scale, including helping build Facebook's multi-factor authentication system for over a billion users. He studied computer science at Purdue and later earned a master's in information assurance from George Washington University, and he now brings that same security-focused mindset to how he looks at blockchain technology as a venture partner at Cadenza Capital Management.
