Simulate Cap Table Dilution

cap_table_simulate_cap_table_dilution

Read-only

SimulateCapTableDilution runs the SAME engine as CloseCapTableRound against the company's current stakeholders and its outstanding SAFEs, for a raise that does not exist yet — no round, nothing persisted. CALL THIS for "what happens if we raise X at Y", "model dilution", "how much do the founders keep", or any post-money ownership question. Do NOT work the answer out yourself, even when the arithmetic looks simple: two implementations of SAFE conversion produce two different founder percentages and only one of them is right, and a hand-computed cap table presented as fact is the failure this tool exists to prevent. It reads each outstanding SAFE's own valuation cap, discount and MFN from the record — do not ask the user for a cap, and do not offer hypothetical caps; they are already stored. Nor do you need share counts first. Use this for a raise that has no round yet. PreviewCloseCapTableRound requires an existing round and cannot answer the same question.
