BrewDog is an increasingly bizarre case study in the microbrewery/crowdfunding space. Their 'Equity For Punks' money- raising efforts received a wide range of legal opinions in different jurisdictions.

Pretty sure no one expected -- given their very loud anti-'sell-out' rhetoric -- that they would sell a 22% stake for £100M to a private equity firm (TSG Consumer Partners) and actually deliver a serious return to said 'punks.'

Edit - 'Serious Return' per BrewDog's own reporting at anywhere between 2,765% and 177% depending on the 'fund' you invested in (https://www.brewdog.com/lowdown/press-hub/tsg-deal)
