That sounds grueling (and stupid) , but I don't think you need a PhD in math to be a mathematician. Presumably, if you make your income doing mathematics, then you are a mathematician. Many professionals with bachelor's degrees sometimes publish in academic journals.

For example, many amateur haskellers have published in academic journals (oftentime in mathematics). I myself have been cited in academic publications despite not having ever gotten a PhD (again related to functional programming). Presumably, someone (And his peer reviewers) thought a blog post I had written about various things in pure FP land was academic enough to qualify for inclusion in a journal.

However, based on my reading of the CEO's profile, blog, etc, it doesn't seem like he fits that definition. In fact, he claims to be a mathematician without as much as one serious blog post or any published content remotely related to mathematics of any kind. I'm not an elitist by any stretch. But to claim to be a mathematician without publishing or speaking on anything related to mathematics, despite being seemingly outspoken on several publishing platforms is incredibly disingenuous
