Sage Realty Corporation traces its roots to 1924, when William Kaufman founded the business and established a service-focused approach to commercial real estate. The company owns and operates a portfolio of Class A office properties in Manhattan and supports tenants with workplace, lifestyle, event, and member experience services. Sage also offers curated office solutions and amenities designed to support day-to-day business needs across its commercial properties. Over time, the company has kept its focus on commercial office assets and on creating managed workplace environments for corporate occupants.
