History of GTCR 

GTCR was founded in 1980 as Golder Thoma & Co. by Stanley Golder, Carl Thoma, and Bryan Cressey, key figures in private equity's early days. Drawing from First Chicago Corp., the firm initially received substantial funding from William Blair, which drove early growth. In 1984, Bruce Rauner’s promotion led to rebranding the company as Golder, Thoma, Cressey, Rauner, Inc., commonly called GTCR.  

In 1998, the firm split into two: GTCR and Thoma Cressey Bravo, both leaders in rollups. GTCR acquired a stake in Captrust in 2020 to bolster its growth and shareholder liquidity, and by 2023, it raised $20 billion in 14 funds. The company continued its expansion, acquiring Cloudbreak Health, Foundation Source, ADT’s commercial division, and notably, Worldpay Inc. to secure $9.4 billion in bank support.

The Future at GTCR

When GTCR set to acquire AssetMark for $2.7 billion, it sought to strengthen its wealth management presence through AssetMark’s technology platform and broad advisor network. The acquisition expands the firm’s reach in wealth tech, supporting growth through innovative advisory solutions tailored for both financial advisors and their clients. As part of GTCR’s strategy to elevate its new acquisition’s services and technology, AssetMark appointed industry veteran Lou Maiuri as chair and CEO for expansion. 

In 2024, GTCR integrated TRANZACT, valued at $632.4 million, into its portfolio to drive growth in direct-to-consumer insurance services. Partnering with Recognize and TRANZACT’s CEO Andy Nelson, GTCR seeks to leverage its data-driven platform to strengthen relationships with leading insurance carriers. This move reflects their mission to develop innovative capabilities, support growth-focused companies, and strengthen its presence across high-demand markets.
