US Seed Round Counts Rebound in 2025 While Median Sizes Surge Over 2× Since 2023
- Seed deal count rose from 219 in 2024 to 204 in 2025
- Median seed round size jumped from €3.9M in 2024 to €4.9M in 2025
- Seed medians more than doubled since 2023's €1.0M median
Across the 219 US seed rounds in 2024 tracked by Brouky, the median round size was €3.9M, notably larger than the €1.56M median for pre-seed rounds that same year.
Seed deal counts were 219 in 2024 and 204 so far in 2025, showing a slight decrease so far in deal volume that may partly reflect expanding data coverage. However, median seed round sizes climbed from €3.9M in 2024 to €4.9M in 2025, marking a significant increase in capital raised per round.
Comparing to 2024, when the median seed round size was €3.9M, the 2025 median increased significantly. The 2025 median seed round size of €4.9M remains well below the median sizes for later stages like Series A (€16.6M) and Series B (€41.4M), but the growth trajectory at seed is clear.
Deal counts at seed remain below the 297 Series A rounds recorded in 2025, indicating that Series A rounds are still more frequent in the tracked data. The median Series A round size in 2025 was roughly 3.4× the seed median, emphasizing the capital step-up between these stages.
