Series A, B, and C are sequential rounds of venture capital financing that fund a startup's growth:

Pre-Seed / Seed ($500K-$5M): Product development, initial hiring, finding product-market fit. Investors: angels, micro-VCs. Typical valuation: $5-20M.

Series A ($5M-$25M): Scaling after PMF. Build the repeatable sales engine. Investors: early-stage VCs. Typical valuation: $20-100M. Key metric: evidence of PMF (retention, engagement).

Series B ($15M-$75M): Aggressive scaling. Expand markets, hire significantly. Investors: growth-stage VCs. Typical valuation: $100-500M. Key metric: revenue growth rate (2-3x YoY).

Series C+ ($50M-$500M+): Market dominance, international expansion, M&A preparation. Investors: growth equity, crossover funds. Key metric: path to profitability or market leadership.

Each round comes with dilution — founders typically own 10-20% by Series C.
