I don’t know of anyone at those companies using clojure and I haven’t seen any tech blogposts by those companies about using clojure. If clojure exists at those companies I imagine it’s a small very niche team.
One very public example of a Clojure shop through and through is NuBank out of Brazil, who employs some 700 "Clojure developers" according to them. In fact they are so committed to Clojure they bought Cognitect last year.
I have no gripe with Clojure, I take issue with someone claiming that Amazon, Apple, and Netflix have systems that operate at scale because of it. Clojure is a fine niche language, but it’s not the secret sauce to big tech web scale.
I was not claiming that, just that also big companies use it. It may not be used for the core of the business but I'm convinced the services that are build with Clojure are reliable, because the language is solid.
