Aquiline, a private investment firm specializing in financial services and technology, has closed its acquisition of SEI's Family Office Services business. As an independent company, the business will revert to its original name, Archway.

After a strong period of growth under SEI's ownership, Aquiline is excited to support Archway with substantial new investment into product, customer experience, and talent.

Archway also announced the appointment of several key executives to lead the newly independent company. Anthony Abenante will join Archway as CEO. Anthony most recently served as Global Head of Equities at Credit Suisse and previously was the CEO of Instinet, where he expanded multi-asset trading capabilities and led platform modernization efforts serving institutional clients across more than 60 markets.

"Archway sits at the intersection of fintech, data, and service—exactly the kind of platform I've spent my career scaling. I'm excited to work alongside our talented team and Aquiline to expand our platform capabilities, enhance client experience, and scale our services to meet growing demand across the family office and private wealth ecosystem," said Abenante.

Steve Meyer will join the Board of Directors as Chairman. "Having been a part of SEI during their acquisition of Archway, I have seen the tremendous progress the business has made under their ownership. I'm incredibly excited to have the opportunity to be a part of this next chapter of the Archway story and continue to build upon its success serving the family office and private banking customers. Archway operates in one of the most dynamic segments of the wealth management market, where complexity and demand for institutional-grade infrastructure has never been higher."
