This is one of the dopest moves from Jay Z period.
According to www.investopedia.com:
On June 16, Jay-Z and Beyoncé released a surprise album titled "Everything Is Love." Apparently Jay-Z was planning another surprise for the month of June.
According to regulatory filings in California, Jay-Z and Roc Nation President Jay Brown are partnering with Walden Venture Capital’s managing director Larry Marcus on a new investment platform named Marcy Venture Partners. Marcus is a Silicon Valley venture capitalist who has previously invested in SoundCloud and Pandora Media Inc.
The name of the fund presumably alludes to Jay-Z’s childhood home: the Marcy Houses, a public housing complex in Brooklyn. The rapper has mentioned the complex multiple times in his lyrics.
