Captable.io has been free practically forever, other than some paid 409a US valuation services.
They are now LTSE Equity, and paid plans start once you’ve raised $1M:
Ownr https://www.ownr.co/ – which is not quite the same thing, especially no scenario modeling, but you can actually fully manage your cap table in Canada with it – is $599CAD / year.
Note: RBC bought Founded.co and renamed it to Ownr.
I guess I need to at least dust off some of Ed’s spreadsheets for modeling from now on
