Full Definition
Series A is the first significant round of venture capital financing, typically raised after a startup has demonstrated product-market fit, meaningful traction, and a clear path to scaling. Series A rounds are led by institutional VC firms and mark the transition from early experimentation to growth execution.
Series A rounds typically range from $5 million to $20 million, with pre-money valuations between $15 million and $60 million. Investors receive preferred stock with liquidation preferences, anti-dilution protections, and often a board seat.

- Monthly recurring revenue (MRR) of $50K-$200K+ for SaaS
