Lightyear Capital has made a majority growth investment in Prosperity Partners, a Chicago-headquartered provider of tax, client accounting and transaction support services, according to PE Hub. The transaction is expected to close in the third quarter of 2026, PE Hub reported.
Prosperity Partners was founded in 2003. Jeremy Dubow serves as the company’s chief executive and co-founder, according to PE Hub.
Unity Partners, which invested in Prosperity in April 2023, will remain an investor through a minority stake in the business, PE Hub reported. That structure gives Lightyear majority ownership while allowing the prior sponsor to keep economic exposure to the company after the new investment.
A majority growth investment is a private equity transaction in which a new investor takes control while backing an operating company’s expansion. The structure can differ from a full sale because existing investors or managers may retain stakes alongside the incoming sponsor.
Prosperity operates in business and financial services, providing tax, accounting and transaction-related support to clients. PE Hub did not report a valuation, purchase price or other financial terms for the investment.
The deal adds another services company to Lightyear Capital’s portfolio activity. For Prosperity, the investment brings in a new majority backer while keeping Unity Partners involved as a minority shareholder.
