What is Pre-Money Valuation?
Pre-money valuation is what your company is worth before new investment hits the bank account. It's the number founders and investors negotiate. Every dollar of pre-money directly affects how much of your company you give away.
Why Pre-Money Valuation Matters
Pre-money is the single most important number in any fundraise. It determines founder dilution. A higher pre-money means you keep more of your company for the same amount of capital raised.
At seed stage, pre-money is more art than science. There's no DCF model that justifies an $8M valuation for a pre-revenue startup. It's driven by market conditions, comparable deals, traction signals, and negotiation leverage.
Pre-Money vs. 409A Valuation
Don't confuse these. Pre-money is a negotiated number for fundraising. Your 409A valuation is a formal appraisal for tax purposes (setting strike prices on employee options). They're determined differently and serve different purposes. Your 409A will almost always be lower than your last round's pre-money.
Formula
Pre-Money Valuation = Post-Money Valuation − New Investment
Founder Ownership After Round = Pre-Money Valuation ÷ Post-Money Valuation
Example
You're raising a $2M seed round and negotiating valuation:
Scenario A: $8M pre-money
- Post-money: $8M + $2M = $10M
- Investor ownership: $2M ÷ $10M = 20%
- Founders retain: 80%
Scenario B: $6M pre-money
- Post-money: $6M + $2M = $8M
- Investor ownership: $2M ÷ $8M = 25%
- Founders retain: 75%
That $2M difference in pre-money costs you 5% of your company. Over multiple rounds, these gaps compound. Negotiate carefully, but don't over-optimize: a fair valuation that closes quickly beats a high valuation that drags on for months.
