Mr. Cooper

Michael DeVito took the helm at Nationstar Mortgage in 2016 and immediately set out to change how people viewed their mortgage servicer. The company dropped the corporate name for Mr. Cooper in 2017, introducing a friendly mascot and a slogan designed to cut through the anxiety of home financing. This rebranding effort helped the firm grow into one of the largest residential mortgage servicers in the United States, managing roughly $937 billion in loans for over 4.3 million customers by 2023.

The independent era ended on October 1, 2025, when Rocket Companies closed its $14.2 billion acquisition of Mr. Cooper Group. This deal created the largest independent mortgage transaction in history and merged Mr. Cooper's massive servicing portfolio with Rocket's technology platform. Following the merger, the standalone consumer website and mobile app retired, directing existing borrowers to manage their accounts through the Rocket portal while retaining the legacy brand name within the broader ecosystem.
