Masttro is built for scale and breadth: hundreds of direct data connections, complex multi-jurisdiction structures, and a team that implements this for large family offices. If that is your situation, a beta product from a young studio is not a substitute.
It also prices independently of assets under management and runs on Swiss infrastructure, two things buyers in this market rightly ask about.
No. Masttro sends a proposal based on your firm and says its pricing does not scale with assets under management. Zahlenwerk prices per team by package; the starting price is on our pricing page.
Masttro describes an investment sub-ledger that exports entries to your general ledger, and says it does not include a full double-entry ledger. Zahlenwerk includes a set of books per legal entity.
Possibly not yet. Larger packages exist, but the product is in beta and built first for small single family offices. A large office with many custodians is better served today by a platform built for that.
Forward one quarter's statements and compare what comes out with the workbook you already trust. That is how the firms in the beta started, and it is a better test than any comparison page.
