Equity Dilution FAQs
What is equity dilution?
Equity dilution occurs when a company issues new shares, reducing existing shareholders' ownership percentage. While the percentage ownership decreases, the value of shares may increase due to company growth.
How does an option pool affect dilution?
An option pool typically causes 10-20% dilution before investment. It's usually created or expanded during funding rounds and affects pre-money valuation calculations.
What's typical dilution per round?
Typical dilution ranges from 15-35% per round, depending on stage, valuation, and amount raised. Early rounds often have higher dilution than later rounds.
How do anti-dilution provisions work?
Anti-dilution provisions protect investors from down rounds by adjusting their conversion price, effectively giving them more shares to maintain their ownership value.
What's a good amount of dilution?
Acceptable dilution depends on growth stage and capital needs. Generally, aim to sell 20-30% in early rounds while maintaining enough equity for future rounds.
How do convertible notes affect dilution?
Convertible notes delay dilution until a priced round, when they convert to equity. The conversion typically includes a discount and/or cap, affecting final dilution impact.
What's the impact of multiple rounds?
Multiple rounds have a compounding effect on dilution. Founders typically retain 15-30% ownership after several rounds, making early dilution management crucial.
How can I minimize dilution?
Minimize dilution by raising at higher valuations, managing option pool size, using alternative financing (revenue-based financing, debt), and maintaining strong growth metrics.

Understanding Dilution: The Pie Analogy
Think of your company as a pie. When you raise money, you're not just cutting the existing pie into smaller pieces - you're making the whole pie bigger. While each slice (percentage ownership) might get smaller, the value of each slice often increases due to the company's enhanced growth potential.
Real-World Dilution Impact
Example Scenario:
- Initial Ownership: 100%
- Seed Round: -20% (80% remaining)
- Series A: -25% (60% remaining)
- Option Pool: -10% (54% remaining)
Company value increased from $1M to $20M, making the smaller percentage worth significantly more.
