SEI Investments Company (together, with its subsidiaries unless otherwise noted, “SEI” or the “Company”) is a leading global provider of financial technology, operations, and asset management solutions that connect the financial services ecosystem across advice, asset management, and administration. Our enterprise operating model unifies technology, trust‑based custody, and investment management to help clients more effectively deploy their capital, whether that’s money, time, or talent, so they can better serve their clients and achieve their growth objectives.

We are headquartered in Oaks, Pennsylvania, and over 5,000 employees support clients from service centers located in the United States, United Kingdom, Ireland, Canada, continental Europe, India, and South Africa.
