What is the name of the venture capital firm that Jay-Z co-founded?

The venture capital firm Jay-Z co-founded is Marcy Venture Partners. He launched it with Roc Nation president Jay Brown and Silicon Valley investor Larry Marcus, formally turning Jay-Z's earlier technology investments into a dedicated investment platform.

The firm's name refers to Marcy Projects in Brooklyn, where Jay-Z grew up. Marcy Venture Partners has focused on consumer brands, technology, media, and lifestyle companies, reflecting Jay-Z's interests beyond music and entertainment. Its investments have included companies such as Uber, Robinhood, and Rihanna's lingerie brand Savage X Fenty through associated investment activity.

This firm is sometimes confused with Roc Nation, Jay-Z's entertainment company, or with a proposed earlier fund connected to Sherpa Capital. Those were related business efforts, but Marcy Venture Partners is the specific venture capital firm named in the question. Jay-Z's investment career also includes ownership and stakes in Tidal, Armand de Brignac champagne, and D'Ussé cognac.
