Jane Street is responsible for the Signals and Threads podcast[1], which I always enjoy. They also contribute a lot to the OCaml language, standard libraries, and do a great job of explaining why OCaml is a great language and paradigm. I've learned a lot because of Jane Street's sharings.
I have no connection or interest in Jane Street but this sure gives me a positive impression of the company.
