Total shares & rate per share
Add one row per share class. Fill in either rate per share or target total to raise below the table and we'll compute the other — then, if you like, apply that rate to every class at once. Each class's own rate stays editable afterward.

What does one shareholder owe?
Paste a shareholder list
Optional. Paste rows from a spreadsheet — one shareholder per line: name, shares, and optionally a class. Tab-separated (a straight copy from a spreadsheet) works best; plain comma-separated works too. A header row is fine — we'll detect and skip it.
