By 2018, Stuart McClure's professional story was well documented: founder of Cylance, architect of AI-based security prevention, author of Hacking Exposed. This BlackBerry blog profile goes somewhere different — to the person behind the career, and specifically to one of the more revealing lenses on that person: cycling.
Cycling at serious levels involves a particular relationship with suffering that Stuart has talked about in several contexts. The sport requires sustained output at the edge of what is physiologically tolerable, and it does so without the intermittent relief of a ball game or the social distraction of a team sport. It is just you, the road, and the decision to keep pushing or not. Stuart's embrace of that kind of voluntary suffering — and his ability to perform through it rather than despite it — is a thread that runs through how he has approached his professional life as well.
The wild dogs element of the profile refers to encounters on cycling routes in less structured environments, where the combination of speed, fatigue, and an aggressive animal requires improvisation under pressure. It is a small but telling detail: Stuart has consistently sought out experiences at the edge of comfort, in cycling as in his professional choices.
The profile was published while Cylance was still an independent company, shortly before its acquisition by BlackBerry in 2019. It captures Stuart at a moment of professional peak — having built and proven his company's thesis — and reveals the personal disciplines and appetites for challenge that have characterized the whole arc of his work.
