Series A/B/C Funding
Sequential rounds of venture capital investment, each typically larger than the last. Series A follows seed funding; Series B and C fund scaling. Each round usually involves giving up equity for capital.
Biological Context
Series funding parallels life stages with different resource needs: seed (germination), Series A (seedling establishment), Series B (rapid growth), Series C (approaching maturity). Each stage has characteristic resource requirements and mortality risks.
Business Application
Each funding round typically requires demonstrating progress on key metrics. Series A proves product-market fit, Series B proves scalable growth, Series C proves path to profitability or market dominance.
