Guide

At pre-seed and seed, and often at Series A, the negotiation is rarely "what is this company worth in a DCF." It is: how much cash do you need, how much dilution will founders take, how much ownership does the lead need for fund math, and what competing term sheets exist.

post-money ≈ round size / target investor ownership
pre-money  ≈ post-money − round size

A $3M raise for ~20% implies ~$15M post and ~$12M pre — regardless of whether anyone "appraised" the code or the brand.

The big idea

Selling a house by the room is the picture. You need $3M of work done; the buyer wants 20% of the house; the implied "value" is $15M. The analogy breaks because later you will sell more rooms, and terms can rewrite who owns the kitchen.

Venture funds have ownership targets because of fund economics and the power law: a seed fund that owns 2% of a unicorn rarely returns the fund; one that owns 15–20% of a breakout might. That structural need collides with founder dilution budgets. The market clears somewhere in between, depending on leverage.

Walking through a $3M seed

You need roughly $3M to get to a Series A-ready metric (say $1M ARR or clear product-market fit evidence). A seed lead typically wants 15–25% of the company. At 20%:

post-money = 3M / 0.20 = $15M
pre-money  = $12M

Raise $4M at the same 20% and the post jumps to $20M — you did not suddenly become more valuable; you sold the same slice for a bigger check, which only makes sense if you can deploy the extra capital usefully.

What actually moves the number

DriverHow it shows up
TeamPrior exits, domain depth, ability to recruit — especially pre-traction
TractionRevenue, growth rate, retention, usage; proof someone pays
MarketTAM narrative investors already believe; category heat
Competition for the dealMultiple serious term sheets compress closing time and raise price
Round dynamicsHot demo days, scarcity of allocation, FOMO

None of these produce a unique number. Two equally "good" seed companies can clear at $8M and $25M post in the same month because one ran a tight process with three leads and the other took the first offer. Process is part of price — see running a fundraise.

Convertible instruments hide the sticker. A post-money SAFE with a $15M cap is economically close to agreeing that the next priced round will give SAFE holders ownership as if the company were worth $15M post (subject to stacking). Caps are valuations in disguise.

Common mistakes

  • Treating a bigger check at the same % as a better company. It is a bigger sale of the same slice.
  • Skipping process. One offer is not a market price.
  • Forgetting SAFE caps already set a floor that converting holders will use.

Check yourself

You raise $3M for 20%. What are post-money and pre-money?

Post $15M, pre $12M. $3M / 0.20 = $15M; $15M − $3M = $12M.

Why do seed leads often need 15–20% rather than 2%?

Fund math: a small stake in even a huge outcome may not return the fund.

Key takeaways

  • Early price ≈ cash needed ÷ ownership the lead must own.
  • Team, traction, market, and competitive tension move the number more than spreadsheets.
  • SAFE caps are valuations in disguise.
