SEI announced that it has entered into a partnership with fee‑only financial planning firm Syverson Strege, which manages $1 billion in assets. The agreement gives Syverson Strege access to SEI’s Wealth Platform, custody, and investment‑management services, allowing the advisor to streamline operations and deliver a modern, digital client experience.

Adding a $1 billion AUM client is a tangible win for SEI, reinforcing its strategy to attract high‑quality fee‑only advisors that generate recurring revenue and create cross‑sell opportunities for other SEI services. The partnership also signals SEI’s continued focus on expanding its ecosystem of integrated technology and outsourcing solutions, a core driver of its growth trajectory.

Syverson Strege will leverage several key features of SEI’s Wealth Platform. The platform’s open‑architecture technology supports digital account opening, digital model management, and advanced planning capabilities, while SEI’s custody services provide secure asset safeguarding, trade settlement, and comprehensive reporting. These capabilities are designed to reduce operational overhead and enhance client engagement, aligning with Syverson Strege’s commitment to fee‑only, client‑centric service.

"After spending almost a year conducting due diligence on several custodians, we chose SEI based on their technology platform and operational capabilities," said Jason Gunkel, Chief Investment Officer of Syverson Strege. "The SEI Wealth Platform will enable us to manage our clients’ accounts efficiently and give our clients a modern, easy‑to‑use experience." Gabriel Garcia, Head of RIA Client Strategy and Experience at SEI, added, "Our ecosystem is designed to be more than a collection of services—it’s a connected framework that empowers firms like Syverson Strege to scale with purpose, innovate with confidence, and deliver a truly elevated client experience."

SEI’s overall market position underscores the significance of this deal. As of September 30, 2025, the company managed, advised, or administered approximately $1.8 trillion in assets, making it one of the largest providers of financial technology, operations, and asset‑management services. By adding a fee‑only advisor with a sizable AUM, SEI not only expands its client base but also strengthens its competitive advantage in a market where fee‑only relationships are increasingly valued for their alignment of interests and potential for long‑term partnership.
