What company owns stride?

Excuse me, could you please clarify which company you're referring to as "Stride"? Is it a cryptocurrency exchange, a financial services provider, or perhaps a tech company of some sort? Without specific context, it's difficult to definitively state who owns Stride. However, in general, the ownership of a company can be determined by looking at its corporate filings, investor relations information, or public announcements. If you could provide a bit more detail about the nature of Stride and the context in which you're asking this question, I might be able to offer a more precise answer.
