Meet Brendan

Co-Founder & Principal Broker

In 2018, Brendan Sweeney founded Byson Real Estate Co, a tech-based real estate firm, alongside his business partner Nick Valletta. Today, Byson provides clients with an unmatched service that spans Buyer, Seller, Landlord, and Tenant representation across commercial and residential markets. 

Byson and its team are credited with representing many clients, from builders purchasing land to develop 250+ unit multifamily complexes to the leasing properties owned by the largest private-held Landlords in New York City.

Before real estate, Brendan was a management consultant at KPMG and advised for some of the largest multi-national banks. He now resides in Long Island City with his family and is highly passionate about prop-tech, and it's effort to move the brokerage industry in the right direction.
