Crunchbase: seed rounds favor $10M+

Seed funding used to mean a relatively small first institutional check. That definition is breaking. Crunchbase’s latest look at 2025 seed data shows U.S. seed money is flowing disproportionately into rounds of $10 million or more, while smaller rounds are getting squeezed. So the headline is not just “seed is bigger.” It’s that seed is splitting into two different markets. (news.crunchbase.com) ### What actually changed at seed? The biggest shift is where the dollars went. More than half of U.S. seed funding in 2025 landed in rounds of $10 million or above. Crunchbase also says the only seed bands that actually grew were the larger ones — $10 million to $50 million, and especially $50 million-plus outliers. Smaller checks did not keep pace. (news.crunchbase.com) ### How big did the outliers get? Very big. Crunchbase highlights more than 20 seed rounds above $50 million in 2025, and one of the wildest examples was Thinking Machines Lab, which reportedly raised a $2 billion seed round. That kind of number would have looked absurd for a seed company a few years ago. Now it sits inside the data instead of outside it. (pipelineroad.com) ### Are there fewer seed deals overall? Yes — and that part matters as much as the giant rounds. Crunchbase says seed deal counts are still down from the 2021–2022 peak, and funding for rounds below $10 million has fallen as well. So this is not a broad-based recovery where everyone gets a little more money. It’s a narrower market where fewer companies are getting funded, and the winners are raising much larger checks.

Training models, buying compute, hiring top researchers, and moving fast all cost real money early. Crunchbase says more than 42% of global seed funding in 2025 went to AI-focused companies, up fr(news.crunchbase.com)eed upward. (news.crunchbase.com) ### Why don’t smaller rounds bounce back too? Because investors are behaving more selectively than they did in the zero-rate era. The old playbook let more founders raise modest seed rounds on a strong idea and a decent deck. The newer playbook asks for sharper proof — traction, technical edge, or a team with unusual credibility. Katie Sta(news.crunchbase.com) on the other. (news.crunchbase.com) ### Does this mean seed is replacing Series A? Not exactly, but the line is blurrier. A $10 million to $30 million seed round can fund a company long enough to hit milestones that used to belong to Series A. That helps the strongest startups stay private longer before pricing the next round. But it also means “seed” now covers two very(news.crunchbase.com)ers. (news.crunchbase.com) ### What does this mean for founders? Basically, the middle is disappearing. Founders who are not in a hot AI cluster or coming out of a top network may find fewer easy entry points. They may need more customer proof, more technical differentiation, or more capital efficiency before institutions engage. In plain English — if investors are writing fewer small seed checks, companies have to look more defensible earlier. (news.crunchbase.com) ### So what’s the bottom line? Seed still exists, but the old mental model does not. In 2025, “seed” increasingly meant either a large, conviction-driven bet on an AI-scale opportunity or a much harder fight for everyone else. That is the real story in Crunchbase’s numbers — not just bigger rounds, but a market that now rewards a much smaller slice of startups. (news.crunchbase.com)
