Wikipedia's core policy is verifiability, not truth. If you put a factual statement into an article, you're required to have a written source that Wikipedia can cite. "Someone who says they're the CEO said so on the talk page" doesn't cut it. If the CEO really wants to get this info into Wikipedia, they can go give an interview to a reputable newspaper, news website, magazine, etc., and then Wikipedia can cite that.

Which brings me to the second policy: notability. If JangaFX is really notable enough to have a Wikipedia page, then surely there will be plenty of coverage of it in secondary sources, so Wikipedia won't have to rely on talk-page statements by random editors claiming to be the CEO.
