SEI Strikes Strategic Partnership with Graphene to Broaden Wealth Infrastructure Offering

SEI Investments (Europe) Limited (SIEL) has entered a strategic partnership with Graphene, a U.K. Infrastructure‑as‑a‑Service provider, and SEI’s venture capital arm has made a concurrent investment in Graphene. Under the alliance, Graphene will adopt the SEI Wealth Platform to power its wealth management infrastructure for clients including independent financial advisers, wealth managers, and family offices.

Graphene’s business model enables firms to own and manage their platform experience and technology stack without building infrastructure internally. With SEI’s platform, Graphene clients can access institutional‑grade operations, data, and onboarding capabilities previously out of reach for smaller firms. From SEI’s side, aligning with Graphene offers access to segments of the U.K. and European wealth market that seek modular, scalable infrastructure.

Executives from both firms emphasize the partnership’s ability to help independent advisory firms scale, differentiate, and retain control over their data and tech experience. For advisors, platforms, and systems integrators, this move matters because it reinforces a trend toward composable wealth stack models—where choosing components rather than monolithic platforms becomes a competitive imperative.
