Masttro, a global provider of wealth technology solutions, has announced a strategic partnership with Arch, a private markets platform, to integrate real-time alternative investment data into Masttro’s platform, offering enhanced wealth visualization across liquid and illiquid assets.
The collaboration aims to provide Masttro’s users with a comprehensive, up-to-date view of their total net worth and portfolio composition, encompassing geography, asset class, manager, and vintage. This integration addresses the increasing demand for private investments among ultra-high-net-worth (UHNW) families, a trend highlighted by BNY Wealth’s 2025 Global Family Office Study, which reported that two-thirds of family offices with over $1 billion in assets intend to increase private equity exposure in the next 12 months, with over half of smaller family offices maintaining allocations.
Arch’s platform, which functions as a private markets portal, enables investors to digitally manage K-1s, alternatives reporting, capital call workflows, and portfolio monitoring. Ryan Eisenman, co-founder and CEO of Arch, stated that the partnership seeks to provide allocators worldwide with greater visibility, extending beyond alternatives data management to modernize the process of tracking and reporting on alternative investments.
Clients of Masttro can integrate Arch’s capabilities directly, streamlining operations by automating manual workflows such as K-1 collection and capital call tracking. This data flow provides granular insights for clients, which include hundreds of single and multi-family offices, RIAs, and major financial institutions globally.
Jay McNamara, CEO of Masttro, commented on the partnership, noting that it simplifies the complexity of managing sophisticated, global portfolios by offering UHNW families a complete, real-time view across all asset classes. He added that Arch’s solution is key in enhancing alternative investment management and gaining deeper insights into portfolio composition.
Masttro’s platform provides real-time wealth visualization, AI-driven efficiency, and seamless integrations, consolidating financial data from over 600 global custodians. The platform supports aggregation, analysis, reporting, storage, and visualization of both liquid and illiquid assets, including alternative investments, collectibles, and real estate.
