Aquiline announces close of Archway acquisition

NEW YORK, July 1, 2025 /PRNewswire/ -- 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."

Archway delivers a comprehensive suite of solutions to family offices, private banks and wealth advisors through the industry's most robust general ledger accounting software platform, along with investment reporting and fund administration services.

Vincenzo La Ruffa, Managing Partner of Aquiline said: "Family offices are an underserved market with increasing complexity of investment portfolios, generational changes and associated operational challenges. We believe Archway has developed the most powerful platform in the industry and we are excited to keep building. Having worked with Anthony as an advisor to Aquiline and board member in the past, we're thrilled to be partnering with him to grow Archway both organically and through complementary acquisitions."

Nick Seibert, Principal at Aquiline added "Having invested in several wealth management software and services platforms, we are excited to leverage Aquiline's depth of experience in partnership with the existing Archway platform and team to build upon its success. Through our experiences with Mirador and Landytech, we see a clear opportunity to grow Archway's client base."

With Aquiline's investment and strategic guidance, Archway enters a new phase as an independent company focused on accelerating product innovation, deepening client partnerships, and expanding its market reach. The company plans to invest in its core platform, enhance its outsourced service capabilities, and build new solutions to meet the evolving needs of family offices and complex wealth enterprises.
