Looking for a few beta testers for an investment portfolio tool

I’m building Borderfolio — a portfolio analytics tool for non-US investors, especially those using IBKR and holding ETFs like VWRA, VWCE, CSPX, VUAA, VT, VOO, etc.

I’m looking for 5–10 people willing to try it with their actual portfolio and tell me what’s confusing, missing, or genuinely useful.

It currently covers portfolio analytics, ETF domicile, dividend withholding tax and US vs Irish-domiciled ETF comparisons.

Free during beta — I’m mainly looking for honest feedback, not selling anything.

If you invest through IBKR and want to try it, DM me.
