Why Compare Funding Scenarios?
Most founders negotiate valuation in a vacuum. You hear "$10M pre-money is standard for seed" and accept it. But the valuation you agree to today cascades through every future round and directly determines how much of your company you own at exit.
A $4M difference in pre-money valuation might sound like a rounding error when you're dreaming about a $1B outcome. But when you model it through dilution across multiple rounds, that $4M can translate to hundreds of thousands or millions of dollars difference in your personal exit.
Scenario comparison lets you model "what if" before you sign the term sheet.
The Setup: Two Seed Round Scenarios
Let's set up two realistic scenarios with the same two cofounders:
- You: 60% ownership
- Co-founder: 40% ownership
Scenario A: Conservative Valuation
| Value | |
|---|---|
| Pre-money valuation | $8M |
| Investment | $2M |
| Option pool | 10% |
| Post-money valuation | $10M |
Scenario B: Strong Valuation
| Value | |
|---|---|
| Pre-money valuation | $12M |
| Investment | $3M |
| Option pool | 10% |
| Post-money valuation | $15M |
Scenario B raises more money ($3M vs $2M) at a higher valuation. But does raising more money mean more dilution? Let's see.
Round 1: What Happens at the Seed
Here's what founder ownership looks like immediately after the seed round closes:
| Stakeholder | Scenario A ($8M pre) | Scenario B ($12M pre) |
|---|---|---|
| You | 48.0% | 48.0% |
| Co-founder | 32.0% | 32.0% |
| Seed Investor | 20.0% | 20.0% |
| Option Pool | 10.0% | 10.0% |
| Total Founder Ownership | 70.0% | 70.0% |
Surprise: Founder ownership is identical after the seed round! Why? Because in both scenarios, the investor buys 20% of the company ($2M/$10M = 20%, $3M/$15M = 20%). The option pool also takes the same 10%. So founder dilution is the same.
The difference emerges later. In Scenario B, you raised 50% more cash ($3M vs $2M). That extra capital might let you hit stronger milestones, command a better Series A valuation, and ultimately dilute less in future rounds.
Round 2: The Series A Effect
Now let's model a Series A. Because Scenario B raised more seed money and hit better milestones, assume a higher Series A valuation:
Series A Assumptions
| Scenario A | Scenario B | |
|---|---|---|
| Series A pre-money | $30M | $50M |
| Investment | $8M | $10M |
| Option pool refresh | 5% | 5% |
After the Series A:
| Stakeholder | Scenario A | Scenario B |
|---|---|---|
| You | 33.6% | 35.3% |
| Co-founder | 22.4% | 23.5% |
| Total Founders | 56.0% | 58.8% |
The gap appears: After the Series A, founders in Scenario B own 2.8 percentage points more. That's because the higher Series A valuation ($50M vs $30M) means the investor takes a smaller percentage for the same dollar amount.
Exit Value: What You Actually Walk Away With
Here's where it gets real. At a $100M exit:
| Scenario A | Scenario B | Difference | |
|---|---|---|---|
| Your payout | $33.6M | $35.3M | +$1.7M |
| Co-founder payout | $22.4M | $23.5M | +$1.1M |
At a $200M exit, the difference doubles. At a $500M exit, that 2.8% is worth $14M extra. The valuation difference that seemed small at seed compounds through every round.
The Option Pool Factor
The option pool is one of the most overlooked dilution drivers. A 10% option pool created before the investment comes entirely out of founder ownership. A 10% pool created after (where the investor shares the dilution) saves founders significant equity.
When comparing scenarios, always model the option pool. A $12M pre-money valuation with a 15% option pool might actually be worse than $8M pre-money with a 5% pool. The raw number doesn't tell the whole story.
Is the Higher Valuation Defensible?
There's a catch. A higher valuation only helps if you can grow into it.
If you raise at $12M pre-money but only hit milestones worthy of $8M, your Series A becomes a down round. Down rounds trigger anti-dilution protections that further dilute founders — sometimes catastrophically.
The rule of thumb: Take the highest valuation where you're confident you can 3-5x it before the next round. If you're not sure you can grow to $30-60M in value, the $8M pre-money might actually be the safer bet.
