Payfinia, an independent payment services provider, today announced the addition of Lisa St. Germain as vice president of Client Success and Justin Epstein as senior director of Product. St. Germain and Epstein have notable financial and payments expertise.
In their respective roles, they will work with clients and partners to enhance their instant money movement workflows for financial institutions and their members/account holders. St. Germain will work with new and existing Payfinia clients to ensure implementations run smoothly and manage the client relationship. Epstein oversees the entire Payfinia money movement product portfolio as well as the service delivery functions.
Keith Riddle, SVP of Business Development for Payfinia, said, “Payfinia is revolutionizing the money movement landscape. We have introduced a unified payments platform that supports a wide array of use cases and workflows, and the market response we are seeing is unprecedented. Lisa and Justin are vital additions to our team, and they will further accelerate our success and growth within the payments ecosystem.”
St. Germain brings more than 35 years of experience to Payfinia, having held leadership roles at several financial institutions and fintechs, developing high-quality and effective training programs and spearheading technology development implementations. Most recently, she was VP of Product Management at Engage fi, leading the product department focused on pricing strategies and operational improvements while managing the full product lifecycle, driving innovation and go-to-market strategies. St. Germain also worked at Fiserv where she was responsible for product strategies and business operations for core banking solutions, serving 500+ clients across the U.S. and Canada.
Before joining Payfinia, Epstein was the Onboarding Strategy Manager for FedNow, where he helped Federal Reserve customers join the FedNow service which launched in 2023. This experience included educating technical, operational and business staff at various financial institutions, businesses and service providers. Epstein began his career at the Federal Reserve Bank of New York and most recently was a senior associate supervising various firms with Libor transition plans and disseminating key themes and challenges across the entire Federal Reserve System.
“The expansive industry knowledge and expertise Lisa and Justin possess is unparalleled,” Riddle said. “2025 is the watershed year for instant payment capabilities as the landscape continues to evolve. The RTP network has already increased the transaction limit from $1 million to $10 million per transaction, and the FedNow Service has adjusted their limit to $1m per transaction, both of which are strong indicators of the increasing demand for instant payment solutions. The unique skill sets they bring to Payfinia will be instrumental as we move forward. We are thrilled to have them as part of our dynamic team.”
