“i am assuming for these purposes that wayne enterprises is a privately held conglomerate…” Kitty Unpretty (previously) lays out a plausible corporate structure for Wayne Enterprises (the fictional company owned by Bruce Wayne, a.k.a. Batman). Highlights include the health division: “Anyone who tries to make anything brain-related gets the side-eye these days. They’ve been burned too many times before. ‘And it’s definitely not supposed to be used to read or control minds?’ any engineer working on a brain-related project will be asked, repeatedly, forever.” and “Spite: A Valid Way To Run A Business Since 1864”.
Also: Wayne Motors (1914): “Founded because one of Bruce’s ancestors really hated Henry Ford. You’d think it would be because of the unabashed antisemitism but it was actually the pacifism. In an ocean of good reasons to hate Henry Ford he found the bad one.”
And: Gotham Solar (1987): “Associating Gotham with the sun in any capacity is hilarious. If It Works In Gotham It’s Gotta Be Good (unofficial motto)”
