Series A In 2026: Capital Is Flowing Faster, But Fewer Startups Are Making The Cut

In 2026, the capital flowing into Series A rounds is accelerating, yet fewer startups are receiving funding. U.S. companies raised $42 billion at the Series A stage this year up to October, a 60% increase compared to the previous year, according to Crunchbase data. However, the number of deals remains similar to recent years. The data reveals a split in the early-stage market, with AI driving demand for capital and some startups growing at an unprecedented pace, while others struggle to convert their initial customers into recurring sales.

Investors are responding by adopting contrasting strategies: some are writing larger checks at seed to gain an edge, while others are waiting until Series B or later for more proof that a business is thriving. This situation leaves companies still in the process of demonstrating growth potential navigating a crunch in Series A funding despite a flood of capital.

The lowest point for Series A funding in the past five years was in 2023, with $23 billion invested in U.S. startups. Since then, Series A investment totals have surged, doubling this year compared to 2023. Meanwhile, the number of rounds has stabilized, averaging 1,200 companies founded at Series A and beyond that raised $1 million or more between 2023 and 2025.

This year, round counts remain in the same range, with a variance of 100 deals. Siddharth Ramakrishnan, a partner at Scale Venture Partners, which primarily leads Series A and B rounds, notes that the application process has become more challenging, leading to a Series A crunch. Investors are competing in two opposing ways: either writing larger checks earlier or waiting until later rounds.

Larger checks of $10 million to $20 million in seed deals are becoming common, while some investors are waiting to invest until later rounds when there's more evidence of a company's success. This divide leaves some founders focusing on turning early customers into repeatable sales processes, as larger checks often hinge on this ability.

Founders who can successfully build a repeatable sales cycle are attracting attention from VCs, who are eager to back those who have proven their growth potential.
