Fannie Mae veteran and mortgage fintech pacesetter Marianne Sullivan currently serves as the chief operating officer at Sagent. She turned to the mortgage servicing sector for her latest challenge: architecting the industry’s first and only cloud-native software platform that powers homeownership and loan servicing lifecycles. Now accelerating progress on Sagent’s next-gen software platforms, Sullivan drives nuanced, progressive innovation in the highly regulated servicing space and plays a crucial role in advancing Sagent’s aim to fundamentally change the dynamics of the U.S. housing ecosystem.

Sullivan has further shaped the industry as she’s injected the expertise gleaned from her time at the top GSE into the mortgage fintech world. Over the last 12 months, her influence was crucial in the renewal of key Sagent customer relationships, the integration of the Mr. Cooper fintech team into the wider organization and the rapid advancement of the next-gen suite of platforms. Throughout an acute market cycle adjustment that began in 2022, Sullivan simplified the extremely complex servicing space for Sagent clients and promoted its open-API enterprise platform so servicers could configure workflows to their unique needs. A visionary who gets the details, she encourages thoughtful, iterative innovation across aging infrastructure, building highly compliant operational pathways within the old systems while incrementally replacing them with the new.
