Madden Asset Management

Madden Asset Management

Madden Asset Management is a registered investment adviser (RIA) that operates as an independent asset manager rather than a family office. The firm was founded by John J. Madden III, who was previously a financial advisor at firms such as Merrill Lynch and UBS. Its public filings describe a focused equity strategy with concentrated portfolios, often holding less than 20 securities and typically invested in small-cap to micro-cap companies. The firm's investment approach is value-oriented and concentrated, with portfolios designed for long-term capital appreciation. Sector tags are not publicly disclosed, but filings indicate a focus on small-cap equities, micro-cap equities, and cash holdings. Geographic coverage is US-centric, and the firm does not publicly report a minimum account size or deployment threshold. Madden Asset Management is a solo practitioner shop — SEC filings list John J. Madden III as the only principal. The firm's professional headcount is not publicly confirmed, but regulatory disclosures indicate no additional employees. No offices beyond Somerset, New Jersey have been identified, and no philanthropic or adjacent vehicles are publicly linked to the firm. The structural differentiator for Madden Asset Management is its extreme concentration and micro-cap focus, which is rare among registered investment advisers. The firm's small size and single-principal structure create a tightly controlled investment process, but also limit operational depth and disclosure. Public information about the firm is sparse, consisting primarily of SEC Form ADV filings and occasional state-level registration records.
