Direct peers

• Brown Harris Stevens: Long-established NYC and Hamptons luxury real estate brokerage serving UHNW buyers and sellers. Directly comparable in serving the same affluent buyer pool in Kean's primary New York markets, though operating as a brokerage rather than a builder/developer.
• Alair Homes: Custom luxury design-build firm with vertically integrated construction and design services targeting high-net-worth clients. Closely comparable business model to Kean's integrated design-build-landscape approach, though operating across Canada/US with a franchise structure.

Broad incumbents

• Corcoran Group: Luxury real estate firm with deep roots in the Hamptons, NYC, and South Florida including Palm Beach. Competes for the same UHNW customer pool and operates in Kean's three core geographies, though as a brokerage rather than developer/builder.
• Douglas Elliman: Major residential real estate firm with strong concentration in the Hamptons, Long Island, and South Florida luxury markets. Comparable UHNW customer base and overlap in target geographies, though focused on brokerage rather than development.
• Ashton Woods Homes: Privately held U.S. homebuilder with a luxury division (Ashton Woods Reserve) building custom and semi-custom homes for affluent buyers. Comparable luxury custom home offering though operating at significantly greater scale and geographic breadth than Kean.
• Trump Organization: Diversified real estate and brand organization with luxury development and licensed branded residences including properties in the Hamptons, Palm Beach, and NYC. Comparable ultra-luxury positioning and trophy-property profile across Kean's three core geographies.
• Sotheby's International Realty: Global luxury real estate network affiliated with the Sotheby's auction brand, with deep presence in the Hamptons, Palm Beach, and Manhattan. Competes for the same pool of UHNW buyers and sellers and represents comparable trophy properties in Kean's target geographies.
