I think Kubera is a big step forward for investors that have a large private portfolio and want to track those investments in an accurate way over time. However, I think there are some simple additional things Kubera can do to improve some elements of the account aggregation snapshot. Namely, better "tax status" of accounts (taxable, tax deferred, AND tax free (i.e. Roth IRA's) ). Better visualization of holdings across exposure type and (improved) tax status. Aggregated IRR by grouping when possible. More flexibility re: performance time period selection, i.e. specific dates, number of days, months, years, to better line it up with market benchmarks. I would love to talk to someone and Kubera as a test case to help improve your product. Thanks for asking. Andy Dudley
