Pre-Money Valuation

Category: Valuation & Cap Table · Level: Entry · Also called: Pre-money, Pre money

TL;DR

The agreed-upon value of the company immediately before a new investment round closes — pre-money + new money = post-money.

Pre-money valuation is the company's value before the new investment is added. It determines what percentage of the company the new investors receive. Pre-money is the headline negotiated number, but the post-money — which includes the new round and any option-pool top-up — is what actually drives ownership math.

Founders sometimes optimize for pre-money valuation while ignoring option-pool shuffles or other dilutive maneuvers that erode their ownership without changing the headline.

Formula

Pre-Money Valuation = Post-Money Valuation − Investment Amount

  • Pre-Money — Company value before the new investment
  • Post-Money — Company value after the new investment
  • Investment — Amount of the new round

Worked example

A founder negotiates a $20M pre-money on a $5M raise. Post-money = $20M + $5M = $25M. Investor ownership = $5M ÷ $25M = 20%. Founder ownership before the round was 100%; after the round (without an option-pool refresh) it's 80%.

Common pitfalls

  • Optimizing pre-money while ignoring the option pool top-up.
  • Confusing pre-money valuation with company worth at exit.
  • Comparing pre-money valuations across deals with very different structures.

When this shows up in a pitch deck

Founders rarely state pre-money valuation in the deck itself; it surfaces in 1:1 conversations with investors after pitch.
