Dilution is part of the valuation decision

A higher valuation is not automatically better if it creates expectations the company cannot meet. A lower valuation is not automatically worse if it brings the right capital and gives the company enough runway.

Founders should evaluate valuation and dilution together because the same raise amount can create very different ownership outcomes depending on the pre-money value.

What to include in a dilution model

A useful dilution model should show more than the investor's new ownership percentage.

  • Pre-money and post-money valuation.
  • New capital raised and expected runway.
  • Option pool creation or expansion.
  • SAFE or convertible note conversion.
  • Founder ownership before and after the round.
  • Next-round ownership under low, base, and high cases.

Use dilution to test round strategy

The right question is not only how much ownership founders give up. It is whether the dilution buys enough progress to justify the next valuation step.

A structured valuation workflow helps connect dilution to milestones, making the round strategy easier to defend.
