The venture world's obsession with mega-rounds masks a brutal reality for seed founders: the Series A has become almost unattainable for most. While global startups closed at least 114 Series A rounds of $100 million or more so far this year—with more than 70% flowing to AI companies—U.S. startups completed just 272 Series A rounds in the third quarter, about 28% fewer than the 377 from a year earlier. Meanwhile, seed rounds held relatively steady at 984 versus 1,059. The math is unforgiving: seed checks are growing (the median U.S. seed round hit about $3 million last year, 3x its 2018 level), yet only 24% of companies that raised a $1 million-plus seed in 2023 have moved past seed, and just 16% of the 2024 cohort. Compare that to 55% or higher through 2020.
Here's what's changed: Series A investors now expect $2 million to $3 million in ARR, sometimes $4 million, and the time from seed to A has stretched past two years. According to Andy McLoughlin of Uncork Capital, if a seed round won't carry you to that revenue bar with six months to spare, a smaller round is actually the better deal. This isn't about product quality anymore. It's about sales execution.
The path exists. Atomic, a New York-based supply chain planning software company founded in 2023, raised a $3 million seed in April 2025 led by Madrona and DVx Ventures, then closed a $12.5 million Series A led by Madrona and Klass Capital about 17 months later. They hit the revenue bar through scalable go-to-market, not founder heroics. Yet most seed companies I encounter have a stronger product than sales motion—and that's the gap that kills them.
The critical insight is that funds of $100 million to $500 million typically lead Series A rounds, and they have finite timelines. Figure out which ones lead at your stage and when their current fund closes, then send the right partners updates for a year before you ask for anything. But more importantly, start building your sales machine now.
A company at $2 million in ARR with a sales process a new hire can run is a better Series A candidate than one at $3 million built entirely on founder-led deals nobody else can repeat. The founders who make it are already planning for the round after this one. The Series A bar isn't really a revenue bar—it's a repeatable sales machine test. If your seed capital can't buy you the breathing room to build that, you've raised too much.
