Trends in seed and early-stage funding in the US over the past decade: number of <$1M rounds are down, $1M-$5M rounds are flattening, but $10-$20M rounds are up
Context & Ripple Effects
This analysis lands mid-arc in a decade-long repricing of the seed stage. The starting point was the institutionalization of seed investing that pushed typical seed checks from $100K-$250K in the early 2000s to $1M-$4M; by late 2018, initial VC funding had fallen to 1,594 US startups over nine months — down 40% from 2015 — even as the median seed round hit roughly $2M.
What this piece adds is the distributional view behind those averages: sub-$1M rounds shrinking, $1M-$5M flat, and $10M-$20M rounds growing. Later coverage confirmed the pattern compounding — $5M+ seed rounds climbed from 45 in 2014 to 180 in 2018 and rounds of $3M+ went from 7.8% to 17% of all seed deals between 2015-17 and 2018-20.
First-order effects
- First-time founders seeking sub-$1M checks face a thinning market: the smallest round tier is contracting, so pre-seed capital increasingly comes from outside the traditional VC round structure.
- Startups able to raise $10M-$20M at the seed stage now compete for a growing pool, effectively pulling Series A-scale capital (median Series A deal size reached $8.6M by 2020) into what was previously seed territory.
Second-order effects
- Seed-focused funds are forced to write larger checks to stay relevant in their own stage, pressuring fund sizes upward and squeezing smaller seed vehicles that cannot follow the market up.
- With fewer companies getting an initial institutional check at all, the funnel narrows downstream — later-stage investors see a smaller, better-capitalized cohort arriving at Series A.
Third-order effects
- If the pattern holds, 'seed' stops describing a check size and becomes a stage label detached from dollar amounts, with the industry structurally bifurcating into a small number of large early rounds and a long tail funded by non-institutional capital.
- Concentration of early-stage dollars in bigger rounds mirrors the broader frontier capital concentration dynamic: more money chasing fewer, larger positions rather than broad-based experimentation.
The trend: US early-stage venture capital is consolidating into fewer but substantially larger seed rounds, shifting the definition of a seed deal upmarket across the decade.
