What Onyx Partners does
Onyx Partners is a privately held real estate investment and asset management firm headquartered in Lakewood, New Jersey, with additional offices in Hoboken, New York. Founded in 2001, the firm acquires, develops, and operates income-producing real estate on behalf of institutional investors and limited partners. Its core product is a diversified portfolio of multi-family residential properties concentrated in the Southeast United States, spanning South Carolina, Tennessee, Georgia, and Louisiana, alongside selectively held commercial assets including the 560,000 square foot property at 111 River Street in Hoboken, acquired in 2022.
The firm has expanded its product surface beyond traditional multifamily into industrial and logistics development, exemplified by the approximately 801,000 square foot Bob's Discount Furniture distribution center developed in Macon, Georgia in 2026. Onyx Partners has also pursued large-scale portfolio M&A, including a $947 million bid for the JCPenney store portfolio in 2025 that did not close, followed by a renewed $934 million offer in 2026. Earlier in its operating history, the firm executed a joint venture with David Werner and Carlton Associates that ultimately sold a multifamily portfolio to Harbor Group for $625 million, demonstrating capital recycling capability.
The business model centers on sourcing, acquiring, developing, and managing real estate assets, with returns generated through a combination of rental income, capital appreciation, asset management fees, and disposition gains. The senior team is led by founder and Chief Executive Officer Jeremy Y. Rieder, with Chief Financial Officer Naftali Leiser and Chief Operating Officer Philip J. Rubinstein, the latter recruited from JPMorgan Chase to support institutional capital deployment. The firm operates with a team of approximately 51 to 100 employees.
