Track every investment a family owns, in one view
Listed equities and bonds arrive through custodian feeds. Private equity and hedge fund positions arrive as PDFs. Real estate, art, and operating cash sit in spreadsheets that no one fully trusts.
Masttro is family office investment tracking software that brings all of it into one reconciled view, mapped to the entities and family members who own each asset. More than 700 direct custodian feeds and AI document processing keep positions and valuations current.
Built inside a family office where wealth never sat in one asset class
Masttro was founded in 2010 by operators working inside a complex, multi-generational family office. Listed portfolios, private funds, operating companies, property, and collections all had to be tracked and reported together, across multiple currencies and jurisdictions.
Masttro was built to track every one of those investments in one place, with 100% data privacy at all times.
"Finally, the most comprehensive and complete system available to manage all types of assets for a family."
— Jose Luis Llamas,
Wealth Management
Public markets, private markets, and everything in the family's portfolio.
100% of investments, mapped to their owners
How does Masttro show who owns each investment?
An investment list tells you what the family holds, but it doesn't tell you which trust owns the building, which LLC made the venture commitment, or which branch of the family benefits from the hedge fund position.
The Global Wealth Map lays out the family's full ownership structure, from individual family members through trusts, holding companies, and LLCs, down to each asset. Because every investment sits under the entity that holds it and every entity connects to the people behind it, you can trace any position to its ultimate owner. Exposure rolls up at each level, so you can see the total for a single trust, a branch of the family, or one family member.
Places every investment under its owning company, trust, LLC, or foundation
Shows total net worth and breaks it down to a single position, property, or painting
Calculates direct and indirect ownership percentages across layered structures
Displays listed, private, real, and passion assets side by side, normalized across currencies
Maps how each asset passes to heirs and beneficiaries
Attaches documents, insurance policies, and contacts to the asset they belong to
Public equities, fixed income, and cash, reconciled daily
Liquid investments rarely sit with one bank. A family might hold equities with three managers, bonds in two currencies, and operating cash across a dozen entities.
Masttro connects directly to 700+ custodians, banks, and brokers, with no screen-scraping and no third-party intermediaries. Transaction-level data lands daily, and every figure is reconciled against the custodian record in both local and reporting currency.

How do you track private equity, venture, and hedge fund investments?
Alternative investments don't come through a data feed. They arrive as capital calls, distribution notices, capital account statements, and NAV reports, usually as PDFs and often not on a set schedule.
Masttro's native Alternatives AI and Documents AI read and tag each document as it arrives. Then, they reconcile it against the commitment and the bank account, and update the valuation. No one retypes a PDF, and there are no surprises at year-end.

Real estate and collections, reported on with the same rigor as the portfolio
Property and collections are often the largest and least-documented lines on a family's balance sheet. They have no ticker and no custodian, and most investment tracking tools have no field for them.
Masttro gives each asset a digital vault built for its asset type. For example, a multi-unit building records every unit. A painting carries its provenance, valuation method, and insurance policy. A wine cellar has an inventory you can filter and export. Valuations for each asset flow into the same net worth view as the rest of the portfolio.
