Fountain Square Asset Management

Fountain Square Asset Management

Fountain Square Asset Management was established in 2021 in Cincinnati, Ohio, by founder Mike Eisenzimmer. The firm operates as a registered investment adviser out of a single Midwest hub, providing wealth management services including discretionary portfolio construction and ongoing financial planning. It advises a mix of local individuals with significant assets, closely held businesses and corporate entities — a Main Street advisory book rather than a national aggregator. The firm's deployment model centers on traditional advisory work: constructing balanced portfolios across equities, fixed income and mutual funds, with financial planning layered over the asset management. It does not operate a fund structure or private placement pipeline. Client accounts span taxable individuals and retirement plan sponsors. The geographic focus is regional — primarily Ohio, Kentucky and Indiana — with no known institutional or endowment mandates. Privately held and run by a single named principal, the firm lacks the multi-professional team or multi-city footprint visible at larger Midwest RIAs. No adjacent venture, real-asset or philanthropic vehicle is disclosed. The platform shares infrastructure with a broader financial services operation under the Eisenzimmer name, but the exact headcount and custody relationships remain opaque. What distinguishes Fountain Square structurally from a wirehouse or a robo-advisor is its high-touch solo-practitioner RIA posture — a model that relies entirely on the principal's personal client relationships and community standing rather than a scalable marketing or institutional sales engine.
