Larry Milstein, 25

GofG readers may recognize Larry Milstein from the young philanthropist circuit, from the Frick Collection Young Fellows Ball to the annual Millennial Pink Party he hosts in the Hamptons with sister, Toby. But he's also the cofounder of PRZM, a Gen Z consulting firm helping brands connect to the younger generation. So far, the firm counts Sotheby's, American Express, and the American Ballet Theatre as clients.
