Liquidation preference trumps headline valuation
Twelve million sounds better than ten. Not if the twelve comes with a double dip.
USD 2 m at 10 m vs 2 m at 12 m is undecidable without the preference term. 1x means the investor takes the money back first; more than 1x, or 'double dipping' (a 15-20% preferred return and then a pro-rata share), shifts the economics against founders. Compare term sheets on valuation and preference together.
The one clause to read before the valuation.
