MacArthur Capital

What MacArthur Capital does

MacArthur Capital Group is a privately held diversified investment boutique founded in 1998 and headquartered at 140 East 56th Street in New York City. The firm develops, invests in, and manages real estate assets — primarily retail condominiums in the New York metropolitan area — while also maintaining a portfolio of financial instruments including mezzanine financings, mortgages, and investment-grade fixed income and money market securities. It is described as one of the largest private owners of retail condominiums in New York City, with operating reach extending across the broader East Coast of the United States.

The firm operates an integrated three-pillar platform: a Properties pillar focused on direct acquisition of income-producing real estate at conservative points of the cycle plus development, redevelopment, and restoration of under-performing assets; a Capital pillar that invests in performing and non-performing financial assets with a stated objective of double-digit compounded IRR and current income emphasis; and a Management pillar providing in-house asset management (property identification, transaction negotiation, capital structuring, post-closing oversight) and property management (rent collection, leasing, bookkeeping, construction management) for both its own portfolio and selected third parties. Strategic alliances with external property managers and real estate brokers extend coverage beyond the group's core operating areas.

The business model combines own-portfolio rental income and appreciation, third-party asset and property management fees, and returns from financial instrument holdings. Go-to-market is sales-led and relationship-based, with no disclosed digital channels or pricing — fees and rental rates are listed as available upon request. The firm runs with a small team of 1-10 employees and contacts include Antony Contomichalos and Viena Margulies. There are no funding rounds, acquisitions, subsidiaries, public filings, or disclosed revenue figures in the available record, consistent with the firm's privately held, principal-invested structure.
