Yelena would find that Ren was sponsored by a few personal tech firms. Several of which promote app development for young entrepreneurs and one that seems to make a business out of jailbreaking phones and enhancing them in different ways. A number of those, in turn, appear to be connected to… something. She will find what appear to be several shell companies propping up those enterprises.

There does not appear to be an actual living person with this name that one might be able to find in the available searches. Mostly, searching just returns this song.
