I doubt any of that matters to Stripe, whose customer base consists of small-to-midsize businesses who need to accept payments over the Internet, oftentimes for marketplace-based business models. By virtue of the problem that they want solved, this group is going to skew towards free markets, free trade, globalization, and all the tenets that r/neoliberalism embraces. They may not themselves want to adopt the label (particularly in front of their own customers, who bring their own baggage associated with it), but they'll be sympathetic to the ideas.

Also, the term is still not known/in use to the general public. The set of people who are politically active via Occupy, Tea Party, Trumpism, #Indivisible, etc. is a small subset of all people, and relatively disjoint from the set of people with successful Internet-based businesses.
