Granite Creek Partners

What Granite Creek Partners does

Granite Creek Partners is a Chicago-based private investment firm founded in 2005 that provides equity and debt capital to lower middle market companies in the United States, with a particular focus on agribusiness and animal health. The firm operates three investment strategies — Corporate Investing, Agribusiness Investing, and Specialized Real Estate Investing — targeting companies generating revenue with annual EBITDA under $10 million that are seeking growth capital, succession planning, management buyouts, or support through transitional events. Granite Creek deploys capital through closed-end fund vehicles including FlexCap II ($200 million, 2019) and the oversubscribed FlexCap III ($300 million, closed November 2023), plus a dedicated $29 million agribusiness vehicle raised in May 2026.

The firm's revenue model is twofold: recurring management fees charged on committed fund capital (typically structured as a percentage of assets under management), and carried interest on profitable exits above the preferred-return threshold. Deal sourcing is relationship-driven, leveraging founder networks, the Small Business Investor Alliance (where partner Brian Boorstein serves as Midwest Regional Chair), and personal industry relationships in sectors dominated by family-owned businesses. A lean team of 11-50 employees operates from a single Chicago headquarters at 222 W. Adams Street.

Granite Creek's portfolio spans agribusiness platforms (Moraine Farmland Partners, Global Animal Products, Ritchie Industries, Seedbox Solution with its QuarterPoint IoT technology), animal health (Veterinary Pharmaceutical Solutions and its Diamond Animal Health subsidiary), medical devices (Royal Biologics, Life Spine), business services (Salem One, CP Direct Holdings, Odyssey Aviation — sold 2025), and technology (Madwire/Marketing 360). The firm distinguishes itself through deep agribusiness operating expertise provided by dedicated Operating Partners Jim Zimmer and Michael Ray, and through its reputation as a founder-friendly partner — recognized by Inc. Magazine on its Founder-Friendly Investors list for six consecutive years from 2020 through 2025.
