Rocket Mortgage has even more data to lean on for its own AI-driven tools after its acquisitions of Redfin and Mr. Cooper this year. 

The lender now has 30 petabytes of proprietary data to train AI models on, Brian Brown, chief financial officer and treasurer at Rocket Companies, parent of Rocket Mortgage, said Dec. 3 during the UBS Global Technology and AI Conference 2025. 

“We think we have a major advantage because of this data,” he said. 

Thirty petabytes is equal to 30,000 terabytes or 30 quadrillion bytes. 

The data includes 60 million archived call logs and client interactions, Brown said. Client interactions can “make our sales team more effective,” he added. 

Additionally, Rocket, Redfin and Mr. Cooper have delivered millions of loans to government sponsored enterprises (GSEs) and those loans can be used to train AI-driven underwriting models, Brown said.  

The acquisitions

Detroit-based Rocket acquired Redfin in July in a $1.75 billion all-stock transaction, according to Rocket. 

Additionally, the company closed its acquisition of Mr. Cooper in October for $14.2 billion, according to Rocket.
