Capital calls, entity structures, custodian feeds, private market valuations — at some point your family office outgrows the workbook. Masttro is built for exactly that moment.


Masttro was built inside a family office by people who lived the same complexity you're managing today.
The entity structures, the manual reconciliations, the alternatives book that doesn't fit anywhere cleanly. We didn't adapt a tool built for traders or retail advisors. We built what we actually needed. That's why it works the way your office works.
Spreadsheet-based aggregation isn't just slow — it's fragile. Masttro connects directly to over your custodians and data sources so the numbers are always current, always complete, and never dependent on a file someone forgot to update.

There's a better way. Capital calls, K-1s, NAV statements, and distribution notices — Masttro reads them automatically and posts the data where it belongs. No spreadsheet, no re-keying, no chasing.
Trusts feeding into LLCs, family partnerships holding real estate, operating companies with outside investors — Masttro maps the full structure from day one, so your team isn't reverse-engineering it six months in.
