The Founders Guide to Equity Dilution
AngelBacked TeamJuly 20, 20257 min read
Every time you raise money, you give up some ownership. Here is how to think about dilution strategically.
What Is Dilution?
Dilution is the reduction in your ownership percentage when new shares are created.
Example:
- You own 50% of 1M shares (500K shares)
- Company issues 500K new shares to investors
- You now own 33% of 1.5M shares (still 500K shares)
- Your percentage decreased but share count stayed same
Types of Dilution
Primary Dilution
From new shares issued to investors in funding rounds. This is normal and expected.
Option Pool Dilution
From shares reserved for employees. Usually created before rounds, diluting founders.
Anti-dilution Protection
Some investors get protection that increases their shares if you raise at lower valuation.
Typical Dilution by Round
Pre-seed
- 10-20% dilution
- Founder ownership after: 80-90%
Seed
- 15-25% dilution
- Founder ownership after: 60-75%
Series A
- 20-30% dilution
- Founder ownership after: 40-55%
Series B and Beyond
- 15-25% per round
- Founder ownership varies widely
The Option Pool Shuffle
Investors often require option pools created before rounds, meaning the dilution comes from founders.
Example:
- You own 80% before raising
- Investors want 20% of company
- They also want 15% option pool
- Your ownership: 80% x (1 - 0.20 - 0.15) = 52%
When Dilution Is Worth It
Dilution is good when:
- Capital helps grow the pie
- Investor adds real value
- You couldnt grow without it
- Terms are fair
Minimizing Dilution
Raise Less
- Bootstrap longer
- Reach more milestones first
- Raise only what you need
Negotiate Better
- Higher valuation
- Smaller option pools
- Better terms
Grow Faster
- More traction = higher valuations
- Revenue reduces dilution
The Psychology of Dilution
Remember:
- 20% of a $100M company beats 80% of a $10M company
- Focus on absolute value, not percentage
- Good investors help grow the pie
