Interesting History
Early Venture Capital
The concept of equity dilution emerged alongside the modern venture capital industry in the 1940s. Georges Doriot, often called the "father of venture capitalism," founded the American Research and Development Corporation (ARDC) in 1946, pioneering the structured approach to startup investment and dilution.
Silicon Valley Revolution
The 1970s and 1980s saw the rise of Silicon Valley, where new models of equity distribution and dilution were developed. Companies like Apple and Microsoft set precedents for how founding equity could be structured and diluted through multiple funding rounds.
Modern Era
The dot-com boom of the late 1990s brought equity dilution into mainstream consciousness, as rapid funding rounds and IPOs became common. This period led to more sophisticated approaches to managing dilution and protecting founder equity.

Managing Equity Dilution: A Strategic Guide
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.
