Pennymac Expands AWS Strategic Agreement to Deploy Enterprise-Grade AI and Commercialize Plaisse Servicing Platform

Pennymac Financial Services, Inc. (NYSE: PFSI) is expanding its multi-year strategic agreement with Amazon Web Services to accelerate its transformation into an AI-driven mortgage technology leader and commercialize its proprietary mortgage servicing platform, Plaisse.

The expanded deal focuses on generative AI adoption, including a conversational AI-powered virtual assistant, and cloud modernization of Plaisse across lending and servicing operations.

Scale and Current Footprint

Pennymac has helped more than 5.6 million homeowners since its founding in 2008. It employs approximately 5,300 people and holds top national rankings as the #1 correspondent aggregator, #3 overall lender, and #3 wholesale lender.

For the twelve months ended March 31, 2026, Pennymac’s production of newly originated loans totaled $154 billion in unpaid principal balance (UPB). As of March 31, 2026, the company serviced loans totaling $720 billion in UPB.

Key Terms of the Expanded Agreement

• AWS becomes Pennymac’s preferred cloud provider.
• Pennymac is leveraging AWS generative AI capabilities to upgrade mortgage application and servicing processes.
• The company has developed conversational AI-powered virtual assistant capabilities powered by Amazon Nova Sonic, including a proprietary Natural Language Virtual Assistant (NLVA) with advanced speech-to-speech capabilities.
• The agreement accelerates cloud modernization of Plaisse, Pennymac’s mortgage servicing platform, to support institutional growth, operational expediency, and industry-wide distribution.
• Additional focus areas include automated document processing, application upgrades, enhanced customer engagement, and data-driven decision-making.

Executive Quotes

“Pennymac has spent 18 years building the operational scale and institutional knowledge to lead this industry — and now we’re translating that into technology that fundamentally changes how mortgages are made,” said Jim Follette, Chief Digital Officer at Pennymac. “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. We chose AWS as our preferred cloud provider because they have the infrastructure to match our ambition.”

“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. “Pennymac is changing that. 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.”

What This Means

The expansion builds on years of prior collaboration and shifts Pennymac from foundational cloud usage toward enterprise-grade generative AI deployment and platform commercialization. The NLVA is positioned to handle after-hours calls, scale operations seamlessly, and optimize customer outreach (identifying new loan opportunities, delivering application links, and scheduling callbacks) while keeping human loan officers in decision-making roles.

No specific go-live dates or migration timelines were disclosed in the announcement.

Actions to Take

Pennymac technology and operations teams should prioritize full cloud migration and feature expansion of the Plaisse servicing platform, followed by broad rollout of the NLVA virtual assistant to maximize after-hours coverage and borrower self-service capabilities.

Other mortgage lenders and servicers should evaluate conversational AI virtual assistants with speech-to-speech capabilities (such as those built on Amazon Nova Sonic) as a potential replacement for fragmented legacy processes in application and servicing workflows, particularly for after-hours borrower support.

AWS financial services and mortgage vertical teams can use this expanded agreement as a reference case when pitching enterprise-grade generative AI and platform modernization to large originators and servicers seeking to commercialize internal technology assets.

Borrower-facing product and compliance teams across the industry should monitor Pennymac’s post-implementation metrics on application completion rates, call resolution times, and borrower satisfaction to assess the real-world impact of speech-to-speech AI in regulated lending environments.
