Marathon Micro Partners
Marathon Micro Partners was established in 2012 as a single-family office in New York. The founding family's wealth origin is not publicly disclosed. The firm operates with a lean team and no external fund vehicles, meaning each investment is made directly from the family's balance sheet. The firm's strategy centers on private credit and real estate, targeting direct lending, structured debt, and opportunistic real estate deals. It has been known to co-invest alongside institutional partners in middle-market transactions. Typical investments span $5 million to $25 million per deal, focused on the United States. The firm avoids early-stage venture capital and public equities. Team size and additional offices are not publicly confirmed. The firm does not maintain affiliated philanthropic foundations or operating companies that are publicly disclosed. As of early 2026, no recent operational events have been reported. Marathon Micro Partners' distinct advantage is its ability to move quickly — no fund structures, no LP approvals, no quarterly drawdown constraints. This permanent capital base lets it hold illiquid credit positions and real estate through market cycles without forced selling.
