BTC Development Corp.
BTC Development Corp. manages South Florida real estate investments for the Carl DeSantis family, built on the $1.8B sale of Rexall Sundown.
BTC Development Corp.
BTC Development Corp. was established to manage and grow the wealth generated by Carl DeSantis, the founder of vitamin and supplement manufacturer Rexall Sundown. DeSantis sold Rexall Sundown to Royal Numico for $1.8 billion in 2000, a liquidity event that created one of Florida's largest private fortunes. The firm has since operated discreetly as a single-family office, concentrating its investments primarily in the South Florida market where the family maintains deep roots. The firm's investment strategy is built around direct commercial real estate development and long-term asset ownership. Its portfolio spans office, retail, industrial, and hospitality properties, with a geographical focus on South Florida submarkets including Delray Beach, Boca Raton, and Miami. Known projects include the development of the Delray Square shopping center and significant holdings in downtown Delray Beach. BTC Development Corp. structures most transactions as wholly owned direct investments, avoiding the fund-management model in favor of permanent capital deployed from the family balance sheet. Beyond real estate, the family's investment reach extends through related vehicles. Carl DeSantis, who passed away in 2023, also founded Celsius Holdings, the energy drink company, serving as its chairman and early-stage investor. While Celsius operates as a publicly traded entity distinct from BTC Development Corp., the DeSantis family's retained equity stake represented a significant portion of their net worth. The firm maintains a lean professional staff characteristic of family offices managing concentrated legacy assets, with operations centered around property management and new development execution. BTC Development Corp. functions as a classic legacy single-family office built around a single liquidity event. Its structure as a privately held development corporation rather than a multi-asset-class institutional platform reflects the family's preference for direct control over tangible assets. The governance and succession framework following Carl DeSantis's death in 2023 has not been publicly detailed, with the office's future direction now a matter of private family decision-making and South Florida real estate industry speculation.

Frequently asked questions
How was the wealth behind BTC Development Corp. generated?
The wealth originated from Carl DeSantis's founding of Rexall Sundown, a vitamin and nutritional supplement manufacturer. He sold the company to Dutch conglomerate Royal Numico in 2000 for $1.8 billion. Following the sale, DeSantis established BTC Development Corp. as the primary vehicle for managing and reinvesting his family's capital.
What is the relationship between BTC Development Corp. and Celsius Holdings?
Carl DeSantis was an early investor and chairman of Celsius Holdings, the publicly traded energy drink company. He provided critical financing and strategic guidance that helped the brand achieve global distribution. While the DeSantis family's Celsius equity is a significant family asset, Celsius operates independently of BTC Development Corp., which remains focused on direct real estate.
Does BTC Development Corp. invest outside of real estate?
BTC Development Corp. focuses almost exclusively on direct commercial real estate development and property ownership in South Florida. The firm does not operate as a multi-strategy investment platform. Broader family wealth includes significant public equity holdings in Celsius Holdings, but those are held outside the development corporation's core operations.
Who runs investment decisions at BTC Development Corp. following Carl DeSantis's death?
The firm's leadership and governance structure after Carl DeSantis's death in August 2023 have not been publicly disclosed. As a private single-family office with no outside investors, the succession of investment authority is a matter of internal family governance, and the firm has not issued statements detailing its new leadership structure.
Is BTC Development Corp. a single-family office or a real estate developer that takes outside capital?
BTC Development Corp. operates as a single-family office, deploying exclusively the DeSantis family's own capital into real estate. It does not raise third-party funds, manage outside LP commitments, or operate a fee-based development business for external clients. All projects are balance-sheet investments owned directly by the family entity.
