Stacker Holdings
Stacker Holdings was founded in the Chicago area by G.R. Kearney and Austin Reichardt, both University of Chicago Booth MBAs who previously worked together at Acuity Capital Partners. The firm is built as an independent sponsor, meaning it does not manage a blind pool of committed capital but raises debt and equity on a transaction-by-transaction basis. That structure gives the partners unusual freedom to hold businesses for as long as value creation requires; they explicitly state they are not looking to buy and flip companies. The firm concentrates on privately held, lower middle-market industrial companies generating $2 million to $10 million in annual owner earnings. Its strategy covers buyout, growth equity, and general venture structures, all within North America. Stacker’s model is operationally intensive: Operating Partner Tim Van Mieghem, co-founder of The ProAction Group, evaluates every acquisition from an operational standpoint and embeds directly with portfolio companies to improve procurement, logistics, and inventory management. One known portfolio company is Acme Finishing, where partner G.R. Kearney serves as president — an example of the hands-on management approach Stacker takes with its holdings. Stacker operates as a four-person team from Elk Grove Village, Illinois, with an extended operational bench through Van Mieghem’s firm. The partners integrate the Entrepreneurial Operating System into portfolio companies, linking employee engagement and culture to financial performance. The firm’s contact page lists a Chicago phone line and invites business owners to discuss objectives even if they are not immediately ready to sell, signaling a long courtship approach. The firm maintains no disclosed AUM or aggregate deployment figure, consistent with its independent-sponsor, deal-by-deal capital-raising model. Stacker’s structural differentiator is its fully independent sponsor architecture: no fund-level AUM, no institutional limited partners dictating a three-to-five-year exit clock, and an operating partner with a separate consulting firm that can be deployed into acquisitions. That design lets the partners pursue control-oriented, operationally heavy industrial deals that a typical fund would struggle to hold for a decade or more, positioning Stacker as a permanent-capital solution for founder-owned manufacturers.

Frequently asked questions
How does Stacker Holdings source its deal flow?
Stacker relies on direct outreach to business owners and relationships built through the Chicago-area industrial community and the partners' previous tenure at Acuity Capital Partners. The firm explicitly encourages owners to contact them even if a sale is not imminent, suggesting they prioritize long-term courtship over auction processes.
Is Stacker Holdings a fund or an independent sponsor?
Stacker is an independent sponsor. It does not manage a committed fund. Instead, the firm raises both debt and equity capital individually for each transaction, which gives it flexible holding periods — there is no predetermined fund life that forces an exit within a set timeframe.
What does Stacker's operational support actually look like for a portfolio company?
Operating Partner Tim Van Mieghem, who co-founded The ProAction Group, leads operational due diligence on every acquisition and then works inside portfolio companies on supply-chain design, procurement, logistics, and inventory control. Partner G.R. Kearney has also served as president of portfolio company Acme Finishing, indicating that Stacker principals are willing to assume full-time interim operating roles.
Which sectors does Stacker Holdings focus on?
Stacker's confirmed focus is industrial technology. The firm targets lower middle-market businesses with $2 million to $10 million in owner earnings. It has not publicly disclosed a negative screen for specific subsectors, but its operational expertise centers on manufacturing and physical goods companies rather than software or services.
Does Stacker Holdings co-invest alongside other private equity firms?
As an independent sponsor, Stacker typically syndicates equity among individual investors and family offices on a deal-by-deal basis rather than co-investing alongside traditional private equity funds. The firm's materials do not describe formal co-investment partnerships with other institutional GPs.
