Spring Bay Companies

Spring Bay Companies traces to 2002 and the liquidity event from Frederick Sontag's sale of Unison Industries. Sontag serves as founder while Daniel Ryan acts as managing director. The office sits in Ponte Vedra Beach and maintains a focused mandate on patient deployment of family capital. Allocations span private equity, venture capital, hedge funds and real estate. The firm executes through direct positions and fund commitments without disclosed co-investor clubs or SPV vehicles. Geographic reach centers on North America with secondary exposure through fund managers. Confirmed philanthropic ties include oversight of The Sontag Foundation and Brain Tumor Network. No public AUM figure or headcount exists. The office lists a single headquarters address at 816 A1A North. Adjacent assets include the family estate and an aviation memorabilia collection. Rick Sontag holds long-standing membership in the Aircraft Owners and Pilots Association. Governance links the investment office directly to the two named philanthropic vehicles, creating an integrated structure that separates grant-making from capital allocation while sharing operational staff.
