Ocean M19 LLC is a Chicagoland-based single-family investment office. The firm holds concentrated allocations to direct private equity, hedge funds, venture capital and real estate and pursues direct investments and partnerships across those strategies. Ocean M19 targets controlling positions in lower-middle-market businesses, typically seeking companies with $10–100 million in revenue and EBITDA in the $2–10 million range. The team includes co-founders Rocco and Roxanne Martino and a senior investment team with Dan(iel) Martino as Chief Investment Officer and Alli Purcell Hayes as Chief Financial Officer. Ocean M19 sits on boards and operates as an active owner—examples of board/portfolio engagements include Precision Products Group, Utility Revenue Services and Phenix Solutions—and a directory listing shows a multi-deal portfolio. The firm emphasizes patient capital, transactional flexibility and an ability to make decisions quickly, and it supplements direct control investments with hedge fund and venture partnerships to access specialized managers and growth-stage founders. These attributes make Ocean M19 a partner for sponsors seeking a family-office LP that can offer control-equity capital, operational support and flexible execution.
