Arch, a modern platform for tracking private market investments, and Archway Group, a provider of technology and outsourced services for single- and multi-family offices, have formed a strategic partnership to offer a unified, end-to-end solution for ultra-high-net-worth (UHNW) investors and their advisors. This collaboration integrates Arch’s alternative investment data into Archway’s accounting and reporting platform, enhancing visibility across both private and public investment portfolios.
The partnership addresses a growing demand for advanced reporting tools as global alternative investments are projected to reach $29.2 trillion by 2029. By bringing together two client-centric firms, the initiative aims to provide investors with a consolidated view of investment data, streamlined accounting and reporting processes, and access to real-time portfolio insights through a secure, all-in-one portal.
Archway Group currently supports nearly 600 UHNW families, including 10 of the wealthiest 25 families in the U.
S., tracking over $750 billion across complex portfolios, trusts, and operating entities. The integration with Arch is expected to allow Archway’s clients to gain a more comprehensive view of portfolio performance and access deeper analytics on alternative investments, consolidating data across various asset classes like investment portfolios, trusts, operating businesses, real estate, and personal accounts.
Ryan Eisenman, co-founder and CEO of Arch, commented on the collaboration, stating, “Archway is one of the most established and respected providers of accounting and portfolio reporting software in the industry. We’ve long served many of the same multibillion-dollar family office clients, and it’s clear that the new Archway management team shares our commitment to delivering an exceptional experience for family offices, private banks, private wealth teams, and alternative asset managers. This partnership represents an opportunity to bring the market a fully integrated alternative investments workflow, reporting, and accounting solution designed to empower both capital allocators and operations teams.”
Anthony Abenante, CEO of Archway Group, also noted, “With decades of heritage as a trusted leader in family office technology and services, Archway is committed to delivering the most advanced and reliable platform in the market. Our partnership with Arch marks a pivotal evolution, bringing simplicity and clarity to ultra-high-net-worth investors by providing a true 360-degree view of their portfolios. Arch is among the most innovative technology firms today, and together we are breaking down legacy silos to unify accounting, investment data aggregation, and reporting into a single, seamless platform. Our mission is clear: to be the trusted ‘single source of truth’ that empowers investors with sharper insights and smarter decisions.”
Arch, described as the “Alternatives Management Platform,” streamlines the entire lifecycle of alternative investing, from portal logins and K-1 collection to automating capital calls and delivering real-time reporting. The platform currently supports $275 billion in private assets for 480 allocators, including 180 single family offices, 100 RIAs and multi-family offices, four of the top 20 global banks, and seven of the top 20 accounting firms.
Brian Lynch, a senior investment analyst at Fingerboard Family Office, a joint user of both platforms, expressed support for the integration. “We see Arch and Archway as two parts of the same whole: both integral pieces of our investment management database,” said Lynch. “It’s exciting to see that same view expressed through this formal partnership, which we expect will save us crucial time and open the door to smarter, more connected ways of working across both platforms.”
The integrated platform is currently in an initial beta phase with joint clients, with full availability expected later in the fourth quarter.
