Series A is the round where the company is expected to have early product-market fit and a glimpse of repeatable growth. Median Series A in the US sits around $12M for SaaS in normal markets, on $40 to 80M post-money valuations. The round funds hiring, scaled GTM, and 18 to 24 months of runway to a Series B.
Lead investors take 15 to 25% ownership and a full board seat. The bar is dramatically higher than seed: a Series A team is expected to articulate a clear repeatable customer acquisition motion and have the metrics to back it.
