KIRR, MARBACH & COMPANY, LLC
Kirr, Marbach & Company, LLC was founded in 1984 by Thomas A. Marbach and John D. Kirr, both of whom continue to lead the firm as managing directors. The firm operates as a registered investment adviser and multi-family office, serving high-net-worth families, foundations, and endowments primarily in the Midwest. It maintains a single office in Columbus, Indiana, a regional base that reflects its client roots. The firm allocates capital across a broad mix of asset classes, including U.S. and international equities, taxable and tax-exempt fixed income, and alternative investments such as private credit and hedge funds. Kirr Marbach structures client portfolios through managed accounts and customized direct investments, often engaging in co-investments alongside external general partners. Its geographic footprint is primarily domestic, with some international equity exposure through foreign-domiciled securities. Kirr Marbach's team size has not been publicly disclosed, but the firm has historically maintained a lean, boutique structure. It operates no separate philanthropic foundation or venture arm, focusing instead on advisory and portfolio management for its family office and institutional clients. As of late 2023, the firm continued to serve its long-standing client base from its Indiana headquarters, reflecting stable, consistent operations. The firm's structural differentiator is its independence — it remains employee-owned and free of external capital, allowing it to tailor separate accounts to each client's specific tax, liquidity, and risk parameters. This bespoke approach sets it apart from larger, product-driven RIAs and aligns it more closely with a multi-family office model.
