Series C rounds fund the next phase of scale: international expansion, M&A, new product lines, or pre-IPO positioning. Companies at Series C usually have $20M+ in ARR, established repeatable growth, and clear unit economics. Investors include growth equity funds, hedge funds, and crossover funds that participate before public markets.
Dilution per round drops at this stage; a typical Series C dilutes founders 10 to 15%, depending on the company's existing cap table and the round size.
