Prior to his venture into real estate, Brendan Sweeney was a management consultant at KPMG. During his tenure, he specialized in financial services, working closely with some of the world's largest multinational banks. He now resides in Long Island City with his family and is highly passionate about prop-tech and its effort to move the brokerage industry in the right direction.
