Stamm Development

What Stamm Development does

Stamm Development Group (SDG) is a privately held, vertically integrated luxury real estate development firm founded in 2016 by Michael Stamm and headquartered across Philadelphia, PA and Delray Beach, FL. The company controls the full development lifecycle through five wholly-owned operating units: SDG|C (luxury general construction in South Florida), SDG|SC (shell and sitework contracting), SDG|RE (luxury residential brokerage in South Florida and investment-property brokerage in Greater Philadelphia), and Coastal Abstract (title insurance in Florida and beyond), supplemented by the non-profit SDG Foundation. SDG develops, builds, and sells high-end residential properties — including a $47.5M Palm Beach Gardens waterfront estate — primarily to high-net-worth buyers, while also representing investors and developers in commercial and mixed-use transactions.

The underlying technology stack is not publicly disclosed; SDG relies on standard real estate and title-industry tools and outsources its website to Agent Image. Revenue is generated across four streams: (1) one-time gains on luxury development sales, (2) construction and shell-contracting fees (professional services), (3) brokerage commissions on both internal and third-party transactions (SDG|RE), and (4) title insurance premiums and closing fees (Coastal Abstract). The go-to-market motion is sales-led and relationship-driven, with no disclosed digital platform or self-serve channel; deal flow comes from in-house agents, brand presence in luxury markets, and capital partnerships with family offices, institutional funds, and national debt funds. Customer segments are HNW individuals purchasing primary or secondary residences, plus real estate investors and developer clients served primarily through the Philadelphia brokerage. Pricing is quote-based and not publicly disclosed, varying materially by property, location, and transaction type.
