The fund closed oversubscribed, surpassing its original $250 million target by $50 million and securing commitments from a geographically and institutionally diverse investor base spanning foundations, global asset managers, insurance companies, pension plans, family offices, and high-net-worth individuals.
The firm was founded by Alex Rolfe and Jon Altman, investment professionals with two decades of combined experience in lower middle-market private equity. Rainier's investment strategy emphasizes control buyouts of family-, founder-, and privately-owned businesses as well as corporate carve-outs. The firm targets investments across North America in four primary verticals: business services, financial services, consumer services, and industrial services.
