What Heartwood Partners (previously known as Capital Partners) does
Heartwood Partners is a middle-market private equity firm headquartered in Norwalk, Connecticut, that traces its roots to 1982 when Brian Fitzgerald founded the predecessor entity Capital Partners. The firm rebranded to Heartwood Partners in September 2020, unifying the brand with a separate entity co-founded by Mark Allsteadt and Robert Tucker in 2004. As of December 31, 2025, Heartwood manages $1.4 billion in assets under management across four funds (Fund I through Fund IV, with Fund III closed at a $600 million hard cap in December 2017) and a $245 million continuation vehicle for The Amlon Group closed in May 2025.
The firm's investment strategy targets family and management-owned businesses in the lower middle market, typically with EBITDA below $10 million, across sectors including environmental services, building products, food and agriculture, packaging, specialty chemicals, niche manufacturing, and commercial services. Heartwood's defining structural differentiator is a lower-debt, higher-equity capital approach — averaging 75% equity capitalization across portfolio companies — which the firm positions as an alternative to traditional leveraged buyout structures. This approach is designed to give management teams greater operational flexibility while allowing selling owners to retain partial equity and continued involvement. The firm has executed 31 platform investments and 61 add-on acquisitions since 2005, with active buy-and-build programs across multiple holdings.
Heartwood generates revenue through standard private equity fund management economics: recurring management fees on committed and invested capital across its funds, supplemented by carried interest realization upon successful exits. The firm sources deals through a developed intermediary network of brokers, investment bankers, accountants, and consultants, supplemented by direct inbound engagement led by business development contacts. The portfolio includes both current operating companies (The Amlon Group, VITALSpace, Norlee Group, Bush Brothers Provision, Somafina, NativeSeed Group) and recently exited platforms (Sur-Seal, Super-Sod, M&Q Packaging, MicroCare). Distribution to limited partners is supported through an Intralinks investor portal, and the firm has been consistently recognized as a BluWave Top PE Innovator, an Inc. Founder-Friendly Investor, and a GCI Top 50 PE Firm in the Middle Market.
