Rowboat Advisors, Inc.

We have built a tax-smart portfolio optimizer specialized for wealth management, and a backtester to analyze and display results using realistic tax. We use linear optimization and other sophisticated techniques to • evaluate the tradeoffs between different (and possibly conflicting) improvements, such as lower fees, lower taxes, better tracking, and more. • increase tax efficiency vs. the current state of the art This helps us choose the best possible portfolio given constraints, such as large external holdings.
