Masttro And Arch Partner To Raise UHNW, Family Office Game

Wealth tech firm Masttro has joined forces with private markets specialist Arch to enhance the way ultra-high net worth families and their advisors manage alternative investments. The integration will allow real-time alternatives data to flow into Masttro’s platform.
Masttro, a global wealth technology provider serving family offices, RIAs, wealth managers, and high net worth individuals, has formed a strategic partnership with Arch, a private markets technology firm.
The collaboration aims to streamline the way investors manage alternative investments by combining Arch’s digital infrastructure with Masttro’s integrated wealth platform, the firms said in a recent statement.
As a result of the integration, real-time data from Arch’s platform – such as K-1 tax documents, capital call notices, performance reports, and other essential materials – will feed directly into Masttro’s user interface. This allows clients and advisors to monitor both liquid and illiquid assets in one centralized location.
The alliance taps into a growing trend of heightened interest in private market investments. According to BNY Wealth’s 2025 Global Family Office Study, two-thirds of family offices managing more than $1 billion in assets intend to increase their allocation to private equity over the next 12 months.
“Arch believes in a future where private market portfolios are as transparent as their public counterparts,” Ryan Eisenman, co-founder and chief executive of Arch, said. “Our partnership with Masttro allows wealth owners and their teams to go beyond traditional data aggregation and adopt a more modern, tech-enabled approach to managing private investments.”
Arch digitizes processes such as capital call tracking, document collection, and alternatives reporting, helping to reduce the administrative burden typically associated with these tasks.
Commenting on the partnership, Jay McNamara, chief executive of Masttro, said the integration enables families to gain a “more detailed understanding of their portfolios, especially in the growing alternatives space.”
Masttro’s platform connects with more than 600 global custodians and aggregates financial data into a single environment. The system also employs artificial intelligence to drive operational efficiency, the firm said.
