What is Dilution?

Definition

Dilution

Dilution occurs when a startup issues new shares to investors or employees, reducing the ownership percentage of existing shareholders.

Why It Matters for Startups

Directly dictates the cap table and dilution structure during fundraising; understanding Dilution helps founders model equity distributions when structuring rounds for founder share planning and equity model forecasts.

Detailed Deep Dive

Dilution occurs when a startup issues new shares to investors or employees, reducing the ownership percentage of existing shareholders. While dilution decreases the slice of the company a founder owns, the goal is to increase the overall value of the company so that a smaller percentage is worth more in absolute terms (e.g., owning 20% of a $100M company is better than owning 80% of a $5M company). Dilution must be carefully managed to ensure founders retain control and motivation.
