Anthiem Ventures

George Weinberger co-founded Datek Securities with Aaron Elbogen in the late 1980s. Datek was one of the pioneering electronic trading firms that helped retail investors access equity markets with reduced costs and faster execution, a model that presaged the online brokerage boom of the late 1990s. Anthiem is a separate investment vehicle, but Weinberger's operating background at Datek shapes the firm's willingness to invest in early-stage technology companies.

Public records show Anthiem's principals own the 813 Quentin Road Medical Building in Brooklyn, a commercial property leased to medical tenants. The firm also participated in the bid process for Long Island Community Hospital (LICH) in Brooklyn, a major redevelopment site, though the outcome of that bid is not publicly confirmed.

George Weinberger serves as Chairman of the board of Maimonides Medical Center, a major teaching hospital located in Borough Park, Brooklyn. This role connects him to healthcare operations and real estate demand in the Brooklyn market, which overlaps with Anthiem's ownership of the 813 Quentin Road Medical Building.

Anthiem targets early-stage venture capital, including seed and startup rounds. No later-stage or growth-equity investments have been publicly identified, though the absence of disclosed portfolio companies limits a fuller understanding of check size and stage preferences.
