The Operating System for Modern Family Offices
Masttro was built inside a family office to solve the realities of UHNW wealth. Today, our global team powers family offices and private banks with a single, trusted view of every account, structure, and alternative asset.
Powering complex wealth at global scale
Masttro's platform capabilities- data aggregation, cash flow management, proprietary custodial connections, customizable reporting, alternatives management, document automation and AI tools - give wealth owners and their trusted advisors ultimate control, transparency, and peace of mind to make informed, data-driven decisions in real time.

Our Origins
Purpose built for family offices, from a family office
Masttro was born inside a multigenerational family office in 2010, built by principals, Javier Gutierrez and Domingo Viesca, who were frustrated by fragmented data, manual reporting, and limited visibility into complex structures and alternatives.
What started as an internal solution to see and manage every dimension of the family’s wealth has become a purpose-built platform for family offices and UHNW advisors worldwide—designed with the same rigor we demanded for our own capital.
Who We Serve
For the families and firms behind UHNW wealth
Our platform is purpose-built for single-family and multi-family offices, financial institutions, professional service firms, and RIAs and the UHNW families they serve.
From complexity-heavy structures to global alternatives, Masttro brings all of it into one real-time view, helping leading firms deepen relationships, sharpen advice, and confidently scale the way they serve their clients.
