Conor McGregor — Proper No. Twelve ($600M Exit)

McGregor launched Proper No. Twelve in 2018 at $25/bottle — aggressively undercutting premium Irish whiskeys. It sold out its initial six-month allocation in 10 days. By 2021, Proximo Spirits acquired the remaining stake for a total deal value of $600 million. McGregor's personal cut: approximately $200 million. The whiskey itself is... fine. It's a smooth, inoffensive blend that serious whiskey drinkers dismiss but casual drinkers enjoy. Proper Twelve succeeded not because it's the best Irish whiskey — it succeeded because McGregor sold it like a prize fight. The marketing was better than the liquid.
