What is dilution in startup funding?
Quick Answer
Dilution is the reduction in an existing shareholder's ownership percentage when a company issues new shares, typically during fundraising rounds. Founders typically experience 15-25% dilution per funding round.
Detailed Answer
Dilution occurs when a company issues new shares, reducing the percentage ownership of existing shareholders. While the number of shares you own stays the same, your percentage of the total decreases.
Types of dilution: - **Percentage dilution** — Your ownership % decreases (most common meaning) - **Value dilution** — Your shares lose value (only if new shares are issued below fair value)
Typical dilution per round: - Pre-seed: 10-15% (SAFE/convertible note) - Seed: 15-25% - Series A: 20-30% - Series B+: 15-25%
A founder starting at 100% ownership might retain 8-15% by IPO after 4-5 rounds plus employee option pool dilution.
Key concept: dilution isn't inherently bad. If a $10M company raises at $40M post-money, the founder goes from 100% of $10M ($10M) to 75% of $40M ($30M). The slice is smaller but the pie is much bigger.
To minimize unnecessary dilution: raise only what you need, negotiate valuation carefully, and understand how option pool expansion affects your ownership.

What is the difference between pre-money and post-money valuation?
Pre-money valuation is a company's value before new investment; post-money is the value after. Post-Money = Pre-Money + Investment Amount. A $10M pre-money with $2M invested = $12M post-money, giving the investor 16.7% ownership.
