Marathon Wealth
Adam Wasserman's Stamford RIA acts as outsourced CFO for UHNW families, structuring direct real estate and credit deals on over $1B in estimated assets.
Marathon Wealth
Marathon Wealth was founded in 2005 by Adam Wasserman, who evolved the firm from a specialized tax advisory practice into a registered investment adviser serving approximately three dozen ultra-high-net-worth families. Unlike many multi-family offices that primarily allocate to third-party managers, Marathon Wealth acts as an outsourced family office, blending comprehensive tax strategy with direct investment origination. The firm is headquartered in Stamford, Connecticut, with a professional team that includes in-house CPA and estate planning capabilities. The firm's investment posture is defined by its direct sourcing model. Marathon Wealth structures a significant share of its own transactions in commercial real estate, private credit, and private equity, aiming to eliminate the double layer of fees that characterizes the traditional fund-of-funds approach. Confirmed areas of focus include direct lending opportunities and multifamily or commercial real estate assets, typically syndicated among its client families. The geographic footprint is concentrated in the United States, though the firm evaluates credit and equity opportunities nationally across middle-market sectors. Public detail on total assets under advisement is limited, though third-party industry estimates place the firm's aggregate client assets between $1 billion and $5 billion. The firm's official communications emphasize a deliberately lean structure, with fewer than 20 professionals managing the full suite of advisory, tax, and investment activities. In recent years, Marathon Wealth has highlighted the growing use of captive insurance companies and other advanced tax-planning structures for business-owner clients—a natural extension of Wasserman's original CPA practice—while continuing to syndicate direct real estate acquisitions. Marathon Wealth's structural differentiator is the adjacency of its tax practice and its investment arm. Most multi-family offices outsource complex tax preparation or operate it as a separate profit center. Here, tax strategy—including estate freeze techniques, installment sales, and captive insurance structuring—is integrated directly into investment decision-making, making the firm function more like a family's in-house CFO than an external wealth manager.

Frequently asked questions
Who runs investment decisions at Marathon Wealth?
Adam Wasserman, the firm's founder and CEO, directs both the advisory and investment activities. He built the firm from a specialized tax practice, and the investment committee structure reflects that origin—decisions typically integrate the tax consequences alongside the investment merits. Day-to-day origination and due diligence are handled by a lean internal team in Stamford.
Does Marathon Wealth operate as a single family office or a multi-family office?
Marathon Wealth functions as a multi-family office and registered investment adviser, serving roughly three dozen ultra-high-net-worth families. It operates on an outsourced model, providing the integrated tax, estate, and investment services that a large single family office would deliver in-house, but shared across multiple unrelated families.
How does Marathon Wealth source direct deals?
The firm sources its own direct transactions—primarily in commercial real estate and private credit—rather than relying on third-party fund commitments. Deals are often syndicated among its existing client base, and the firm leverages its CPA-originated network of business owners and real estate operators to find off-market or lightly marketed middle-market opportunities across the United States.
Does Marathon Wealth maintain philanthropic structures, and how are they separated?
Marathon Wealth's advisory services include the use of donor-advised funds and private foundation planning for client families, but the firm has not publicly disclosed a separate philanthropic arm or foundation of its own. Tax-efficient charitable giving is integrated into the overall wealth-planning work the in-house CPA team provides.
Is Marathon Wealth an RIA or a family office?
It is both in practice. Marathon Wealth is legally structured as a registered investment adviser (RIA) and files with the SEC, but it operates as a multi-family office in function, delivering comprehensive tax preparation, estate planning, and direct investment sourcing that goes far beyond standard wealth management. The RIA registration gives it a regulatory framework more transparent than many private family offices.
