The median US seed round in 2025 is about $3.4 million raised at a $16 million post-money valuation — roughly 18% dilution — yet only 13–15% of those companies will reach a Series A within two years.
That is the tension every founder needs to understand before they raise. Seed checks and valuations are at all-time highs, but the bar to graduate to a priced Series A has risen faster than the money. Bigger seed, narrower funnel. The numbers below come from Carta, PitchBook, AngelList, and Crunchbase, and they tell a more sobering story than the headline round sizes suggest.
Seed Round Statistics 2025: The Headline Numbers
In 2025, the median US seed round is approximately $3.4 million at a $16 million post-money valuation, with founders parting with about 18–19% of their company. Round sizes and valuations are the highest on record, but only 13–15% of seed-funded startups raise an institutional Series A within 24 months — less than half the conversion rate seen in 2020.

Seed Round Size and Valuation by Year
The clearest way to read seed round statistics is the six-year trend. Round sizes climbed steadily, post-money valuations re-inflated past their 2021 peak, dilution drifted down as valuations outpaced check growth, and the seed-to-Series A conversion rate collapsed. All four trends are happening at once.
| Year | Median Round | Median Post-Money | Median Dilution | Seed→A in 24mo |
|---|---|---|---|---|
| 2020 | $2.0M | $9M | 21% | 31% |
| 2021 | $2.8M | $13M | 22% | 30% |
| 2022 | $3.0M | $14M | 21% | 19% |
| 2023 | $3.1M | $14.5M | 20% | 16% |
| 2024 | $3.1M | $15M | 19% | 15% |
| 2025 | $3.4M | $16M | 18.5% | 13–15% |
Figures are 2025 estimates blended from Carta, PitchBook, AngelList, and Crunchbase US seed financing data. Conversion is the share of each seed cohort raising a priced Series A within 24 months; 2024–2025 cohorts are still maturing and may rise modestly with longer windows.
The most overlooked line in the table is the last column. A founder raising in 2020 had nearly one-in-three odds of getting to Series A within two years. A founder raising in 2025 has closer to one-in-seven. The money got bigger; the graduation funnel got dramatically tighter.

Seed Round Statistics by Sector in 2025
The median masks enormous sector variance. AI and machine learning seed rounds in 2025 carry roughly a 40% valuation premium over the rest of the market, driven by competitive investor demand and the perception that compute-heavy teams need more capital. Consumer and pre-product startups sit at the bottom of the range.
| Sector | Median Round | Median Post-Money | Premium vs. Median |
|---|---|---|---|
| AI / Machine Learning | $4.5M | $20M | +40% |
| Fintech | $3.5M | $15M | +6% |
| Enterprise SaaS | $3.2M | $14M | -13% |
| Healthcare / Bio | $3.0M | $13M | -19% |
| Climate / Energy | $3.3M | $14M | -13% |
| Consumer | $2.2M | $11M | -31% |

Seed to Series A Conversion: The Number That Actually Matters
If you only take one statistic from this post, make it this: the majority of seed-funded companies never raise an institutional Series A. The 13–15% two-year conversion rate is not a rounding error — it is the defining feature of the 2025 market. Two things drove the collapse.
The Series A bar moved up
In 2021, a Series A often required $1M ARR and a story. In 2025, investors increasingly want $1.5–$2.5M ARR growing 2.5–3x year over year before they write a priced A. The milestone gap between a $16M seed and a $40M+ Series A widened, and many companies simply cannot clear it on a single seed.
Seed got front-loaded
Larger seed rounds buy longer runway, so the median time from seed to Series A stretched to 24–28 months. Many founders now raise a seed extension or a second seed instead of graduating, which means the company is technically still "at seed" two and three years in — depressing the clean conversion number.
For founders, the practical takeaway is to raise a seed sized to clear the real Series A bar, not the one from three years ago. For investors, it means seed reserves and the willingness to lead a bridge matter more than ever. The full vintage-level conversion and return data lives on the VC performance dashboard.
How Seed Rounds Are Structured in 2025
The mechanics behind these seed round statistics matter as much as the medians. Three structural facts define the 2025 seed market:
~87% use SAFEs, not priced equity
The post-money SAFE is now the default seed instrument. The median seed valuation cap sits around $13–14M, and most rounds never see a priced lead until Series A.
Stacked SAFEs hide real dilution
Founders raising on multiple caps over 12–18 months frequently underestimate total dilution. Three SAFEs at different caps can convert to 25%+ combined ownership when the priced round finally happens.
Party rounds are back at seed
A typical $3.4M seed in 2025 has 8–15 investors rather than one lead writing the whole check. That spreads risk but can leave companies without a committed lead to drive the next round.
The seed market in 2025 is generous with capital and brutal with graduation.
Raise a $3.4M seed if you can — but size it to clear a Series A bar that only 1 in 7 companies actually reaches.
