Landmark Management
Landmark Management traces its roots to 1997 when Earl “Trip” Samson III and Allyson D. Samson established the firm following their tenure at Compton Capital Partners. The wealth under management originates from the founders’ investment advisory practice rather than a single industrial fortune. Services center on portfolio construction, tax planning and consolidated reporting for a limited number of families. The firm allocates across early-stage venture, growth equity, secondaries, hedge funds, private equity and real estate. Confirmed positions include Sakonnet Vineyards and Landmark Vineyards. It also operates a Qualified Opportunity Fund focused on mixed-use assets in the United States. Geographic reach covers North America and Europe. Investment types include fund-of-fund commitments, direct co-investments and alternative venture structures. Landmark employs an undisclosed number of professionals and maintains its headquarters in New York. In June 2023 Rosemont Investment Group acquired a 40% minority stake, with Markel Corporation providing backing to Rosemont’s permanent-capital model. Adjacent vehicles include LMI Partners, LLC. Earl Samson previously served as Founding President of Sakonnet Point Club and Chairman of the Board of Trustees at Darrow School. Ownership structure features an external minority partner alongside the founding principals, creating a hybrid governance model uncommon among traditional multi-family offices. Succession planning centers on J. Daniel Graham as co-managing partner. Philanthropic activity appears through support of the East Harlem Tutorial Program and the John A. Hartford Foundation, kept separate from investment operations.
