Madison Valley Partners
Madison Valley Partners was founded in 1997 by David Weitz, a former attorney who structured the firm around the wealth generated by the Slifka family, whose patriarch founded the Global Electric Company. The firm operates as a multi-family office, serving the Slifka family alongside a small number of additional families, though it does not publicly disclose the full principal roster. Strategy centers on direct real estate investments, fund commitments to private equity and venture capital managers, and hedge fund allocations. Known portfolio activity includes co-investments in commercial real estate in the Northeast United States and stakes in private equity funds focused on middle-market companies. The firm also maintains exposure to European markets, primarily through real estate and private equity partnerships. Madison Valley Partners does not disclose AUM or team size publicly. The firm has been described in industry coverage as managing several hundred million dollars, with an operational style that emphasizes long-term relationships with a concentrated set of external managers. No recent operational events (within 24 months) are publicly documented for this firm. The firm's structural differentiator is its hybrid model: a single-family-office origin that evolved into a multi-family office while remaining tightly controlled by its founding principal. This allows Madison Valley to co-invest alongside principals and external families without the overhead of a large institutional platform.
