PennyMac jumps on voice agents with Amazon partnership

In its latest push toward advancing artificial intelligence goals, PennyMac Financial Services will strengthen its partnership with Amazon Web Services, enhancing processes with borrower-facing conversational AI agents and modernization of its servicing platform.

The investments underscore the company's strategy for "a comprehensive AI transformation" with the backing of AWS' engineering resources to focus on cloud optimization, PennyMac said. 

The proprietary natural-language virtual assistant, developed around speech-to-speech technology offered by Amazon Nova Sonic software, will be able to speak to customers around the clock by phone with real-time responses that can identify loan options, schedule callbacks and deliver application links.

"Buying a home is one of the most important financial decisions a person will ever make, and for too long the process has felt like it was designed to slow people down," said Beth Fatusin, director, worldwide financial services, AWS, in a press release. 

"By building their AI-powered virtual assistant on AWS, they're giving borrowers a fast, clear, human-feeling experience at every step of the application."

The new alliance will address a range of tasks and responsibilities at PennyMac, including automated document processing, customer engagement and data-backed decision-making, the company said. 

The partnership is also set to expedite development and improvement of PennyMac's cloud-based proprietary servicing platform, Plaisse, in order to support the company's growth in the segment.  

"We chose AWS as our preferred cloud provider because they have the infrastructure to match our ambition," said PennyMac chief digital officer Jim Follette in a press release.

"Our AI-driven virtual assistant and the continued modernization of Plaisse are the next stage of a deliberate, long-term strategy to deliver a superior, seamless journey for our borrowers." 

PennyMac's recent expansion and AI moves

The rollout of borrower voice agents is the latest artificial intelligence-focused development from the Westlake Village, California-based PennyMac this month, following the company's appointment of enterprise AI executive Tiffany To to its board last week. 

The moves come as lenders, servicers and software providers explore the possibilities presented by both agentic voice- and chat-based AI tools in providing near-instant communication and interactions this year, with the likes of Newrez and ICE Mortgage Technology rolling out such capabilities recently to assist borrowers and staff. 

The upgrades to Plaisse will also support PennyMac's servicing expansion, with the AWS announcement arriving four months after its multimillion-dollar acquisition of former Cenlar subservicing assets. The addition of the Cenlar portfolio boosted unpaid principal servicing balance at PennyMac above $1 trillion.

According to Home Mortgage Disclosure Act data, PennyMac ranked as the fourth-largest U.S. lender by loan count in 2025 with just under 101,000 originations in wholesale and consumer-facing channels. It sat in seventh place based on dollar volume of $35.4 billion. 

Founded in 2008, PennyMac also stands on top as the nation's biggest mortgage correspondent aggregator.
