⚡ Dilution at a Glance
📊 Key Metrics & Benchmarks
Dilution is the reduction in existing shareholders' ownership percentage when a company issues new shares — typically during fundraising, employee option grants, or convertible note conversion.
Typical dilution per round: - Seed: 15-25% dilution - Series A: 20-30% dilution - Series B: 15-25% dilution - Option pool: 10-20% reserved
Example: A founder with 50% ownership who raises a Series A with 25% dilution now owns 37.5% (50% × 75%). After Series B with 20% dilution: 30% (37.5% × 80%).
Anti-dilution provisions: Investors often get anti-dilution protection (weighted-average or full-ratchet) that protects their ownership in down rounds, shifting dilution further to founders and employees.
🌍 Where Is It Used?
Dilution is implemented across modern technology organizations navigating complex digital transformation.
It is particularly relevant to teams scaling beyond their initial product-market fit, where operational maturity, predictability, and economic efficiency are required by leadership and investors.
👤 Who Uses It?
**Technology Executives (CTO/CIO)** leverage Dilution to align their technical strategy with overriding business constraints and board expectations.
**Staff Engineers & Architects** rely on this framework to implement scalable, predictable patterns throughout their domains.
💡 Why It Matters
Dilution directly determines how much of the eventual exit founders and early employees receive. Understanding dilution math helps engineering leaders evaluate equity compensation offers.
