PrivateTechShares ISO/AMT Calculator

Hi PH 👋 I kept seeing startup employees get blindsided by the tax bill after exercising their ISOs — sometimes tens of thousands in AMT they hadn't planned for, owed in the year they exercised, before selling a single share. Most calculators for this are buried in a CPA's spreadsheet or gated behind a signup. So I built a free, no-signup one that gives you the honest total in a few seconds: strike cost + the AMT (ISOs) or ordinary tax (NSOs). It's a planning estimate, not tax advice. Would love to hear what other equity questions you'd want a tool like this to answer — happy to talk ISOs, AMT, or selling private shares in the thread.
