Life Jay-Z invests in compostable phone cases By weekster Posted on 1 week ago 1 min read Share on Facebook Share on Twitter Share on Google+ Jay-Z (49) has found another new initiative to invest his money. The company of the world’s richest rapper has partnered with a brand that makes compostable phone cases, reports The New York Post. The husband of Beyoncé is said to have invested five million dollars in Pela. The covers, which can be used entirely for compost, cost between 30 and 50 dollars. The rapper, who has more than a billion dollars in his bank account, regularly invests in new initiatives. He did that last summer in HipCamp, a sort of Airbnb for campsites. The rapper also bought shares in companies such as Uber and the champagne brand Armand de Brignac.
