Integration will streamline workflows and automate processes for tracking, managing and reporting on alternative investments

Masttro, the global leader in wealth tech solutions for family offices, registered investment advisors (RIAs), wealth managers and wealth owners themselves, today announced a strategic partnership with Arch, the private markets portal of portals, providing investors with the first digital platform to manage their K-1s, alternatives reporting, capital call workflows, and portfolio monitoring. The integration will route real-time alternative investment data into Masttro’s next-generation platform, enabling enhanced wealth visualization across liquid and illiquid assets and liabilities in a single dashboard.

BNY Wealth’s 2025 Global Family Office Study revealed that two-thirds of family offices with more than $1 billion in assets plan to increase exposure to private equity (PE) funds in the next 12 months. Meanwhile, more than half of family offices with less than $1 billion will continue allocating to PE funds. As demand for private investments proliferates among ultra-high-net-worth (UHNW) families, Arch offers Masttro’s users a comprehensive, up-to-date view of their total net worth and their portfolios, encompassing geography, asset class, manager, vintage and more.

“Arch believes in a future where private markets portfolios have the same level of transparency as public investments,“ said Ryan Eisenman, co-founder and CEO of Arch. “Partnering with Masttro provides allocators across the world with greater visibility, going beyond alts data management to modernize the time-consuming process of managing, tracking and reporting on alternative investments.”

Clients may choose to easily integrate Arch’s powerful alternatives data management and reporting capabilities directly into Masttro’s platform, which serves hundreds of single and multi-family offices, RIAs and major financial institutions globally. By eliminating manual workflows such as K-1 collection and capital call tracking, Arch enables a seamless flow of data that gives Masttro’s clients access to deep, granular insights.

“Masttro simplifies the complexity of managing sophisticated, global portfolios by giving UHNW families a complete, real-time view across every asset class,” said Jay McNamara, CEO of Masttro. “As we continue to innovate and enrich the user experience, Arch is a key player among alternatives technology providers with a solution that empowers clients to enhance alternative investment management and gain deeper insights into portfolio composition.”
