Series C is a late-stage venture capital funding round that companies typically raise after demonstrating strong market traction, achieving profitability or near-profitability, and preparing for major growth initiatives such as geographic expansion, strategic acquisitions, or an initial public offering. At this stage, companies have proven their business model works at scale and are seeking capital to accelerate growth and dominate their market before going public or being acquired.
Companies reaching Series C have usually survived multiple funding cycles and demonstrated sustained revenue growth, often exceeding $50 million in annual recurring revenue. The average Series C round in 2023 ranged from $50 million to $100 million, though some high-profile deals exceeded $200 million. Valuations at this stage typically range from $200 million to over $1 billion, earning successful companies "unicorn" status.
Why It Matters
Series C represents a critical inflection point where venture investments transition from high-risk growth bets to more mature expansion plays. The risk profile shifts dramatically—companies at this stage have validated their market, refined their unit economics, and built repeatable sales processes. For investors, Series C offers lower risk than early-stage rounds while still providing meaningful upside potential before public market valuations. Late-stage investment firms, hedge funds, and private equity groups often enter at this round, bringing different expertise and expectations than traditional venture capitalists.
Example
A cloud-based HR software company raised a $15 million Series A in 2019, followed by a $40 million Series B in 2021. By 2023, they reached $60 million in annual recurring revenue with 500 enterprise customers and positive unit economics. They raised an $80 million Series C led by a growth equity firm to expand from the U.S. into Europe and acquire two smaller competitors. The Series C valued the company at $600 million, with existing investors from Series A and B maintaining their positions. Eighteen months later, the company went public at a $1.2 billion valuation, providing Series C investors with a 2x return in under two years.
