Anthiem Ventures

George Weinberger, as Founder and Managing Partner, is the central decision-maker. His long-time business partner Allen Gross co-invests alongside him in real estate through LANA Acquisitions, LLC, while the Double U Master Fund L.P. appears as an associated vehicle in public filings. The firm does not list a separate investment committee or additional investment professionals.

Anthiem's disclosed activity points to direct deals only — both in venture capital and real estate. There is no evidence of the firm committing capital to external venture funds, private equity funds, or real estate funds as a limited partner.

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.

Anthiem does not publicly disclose whether it manages outside investor capital. The firm's structure — with entities like the Double U Master Fund L.P. and LANA Acquisitions, LLC tied to the same principals — suggests a model focused on partner-level capital rather than a marketed fund open to institutional LPs.

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.
