Review Checklist
What reviewers usually validate first
These are the areas teams usually discuss first once the valuation calculation is visible.
Confirm the pre-money is the agreed term, not a back-calculated number.
Include all options, warrants, and convertible instruments in the existing share count.
Most term sheets create the pool pre-money, diluting existing holders, not the new investor.
Outstanding convertibles increase the share count before the priced round shares are issued.
Verify the calculated PPS matches the Series term sheet within rounding.
Ensure the share register is up to date before running the model.
