Startup fundraising statistics in 2026: what the data actually shows
Fundraising benchmarks shift quickly. A round size that looked reasonable in 2021 may look outsized or undersized depending on when a founder is reading this. Timelines have lengthened. Graduation rates have dropped. Valuations have hit new highs despite fewer deals closing.
This article draws from PitchBook, Carta, Crunchbase, CB Insights, and the National Venture Capital Association. Where figures differ across sources due to methodology, that is noted.

Seed round sizes and valuations (2024-2026)
Seed valuations have moved up sharply over the past two years, even as deal count has declined.
Median seed round size reached approximately $4 million in Q4 2025, up from $2.5 to $3.5 million in 2024 (PitchBook Q4 2025 Analyst Note). Deal count at seed fell 29% year-over-year, but median valuations rose 19%.
Median seed post-money valuation hit $24 million in Q4 2025, a new all-time high. That is up from $18 million in Q4 2024 and $16 million in Q4 2023 (Carta State of Private Markets Q4 2025).
The top decile looks very different. PitchBook tracks "consensus" seed rounds, which are priced at roughly $40 million pre-money - nearly three times the market median. The 95th percentile seed post-money valuation reached $80.5 million in 2025, compared to $28.5 million in 2019.

The gap between median and top-decile seed pricing reflects a bifurcated market. Companies with AI traction, repeat founders, or top-tier institutional backing command premiums that no longer resemble the broader market.
Series A round sizes and valuations
Series A valuations climbed sharply through 2025, driven by AI competition and a smaller qualifying cohort relative to the post-2021 boom.
Median Series A post-money valuation reached $78.7 million in Q4 2025, up 37% year-over-year from $57.5 million in Q4 2024 (Carta). The typical round size at Series A sits between $10 million and $15 million, with a $12 million benchmark across sectors.
Implied pre-money valuation at Series A is approximately $65 to $70 million based on current round size data. PitchBook's Q3 2025 US VC Valuations Report notes that median pre-money figures are reaching new highs driven by competition for AI-related deals.

The 37% jump in a single year has two causes. Fewer companies are reaching Series A, which raises the quality floor. And investors are competing harder for the smaller pool of deals that do qualify.
Series B round sizes and valuations
Series B rounds have grown larger as the time between rounds has extended and companies arrive with more mature metrics.
Median Series B round size is $30 to $40 million in 2025, with AI-native companies and high-ARR-growth companies raising $40 to $75 million. Median Series B pre-money valuation reached $118.9 million in Q3 2025, up from $102.8 million in Q3 2024 (Carta).

Time between funding rounds
The fundraising calendar has extended significantly since the 2021 peak. Founders who modeled their timelines on 2020 or 2021 data are working from outdated assumptions.
Median time from seed to Series A was 774 days (~2.1 years) among companies raising Series A in Q4 2024, up from 420 days (~1.2 years) in Q4 2021 - an 84% increase over three years (Carta). For fintech companies specifically, the median stretched to 971 days (~2.7 years), 25% longer than the cross-sector figure.
39% of startups now take three or more years to go from seed to Series A, according to Carta's 2025 data. SaaStr analyzed 3,365 startups and concluded that founders should plan for seed runway of at least three years before targeting Series A.

The median of 28 months between rounds in 2024 was the longest span recorded since 2012. This has direct implications for how much capital a startup needs to raise at each stage in order to reach the next milestone with enough runway to run a competitive process.

Equity dilution by round
Dilution benchmarks have shifted. After declining from 2019 through early 2024, Series B dilution spiked in early 2025 while seed and Series A remain relatively stable.
Median dilution at seed is approximately 19 to 20%, consistent with Q1 2024 Carta data showing 20.1%. Series A dilution sits around 18 to 20%, down slightly from the 20.5% recorded in Q1 2024. Series B dilution reached 22.7% in Q1 2025, up sharply from 16.7% in Q1 2024 (Carta).
Equity dilution benchmarks (2024-2025)
| Stage | Q1 2024 | Q1 2025 | Source |
|---|---|---|---|
| Seed | 20.1% | ~19-20% | Carta |
| Series A | 20.5% | ~18-20% | Carta |
| Series B | 16.7% | 22.7% | Carta |
Source: Carta dilution data Q1 2024 and Q1 2025
The Series B dilution spike in early 2025 reflects more expensive capital at that stage relative to recent history. Founders selling 20 to 24% at both seed and Series A face cumulative dilution of around 40% before reaching Series B, which shapes how much of the company remains in founder and early employee hands by the time a company approaches exit.
Seed-to-Series A graduation rates
Graduation rates - the share of seed-stage companies that go on to raise a Series A - have contracted sharply since the 2021 peak. 2024 data suggests stabilization but not recovery.
The 2022 cohort produced only a 15.4% graduation rate within two years, compared to 30.6% for the 2018 cohort (Incisive Ventures, June 2025). That near-halving reflects both a tighter fundraising environment and the lag effect of companies from large 2021 seed classes competing for a smaller pool of Series A capital.
Q1 and Q2 2024 cohorts showed an 8.9% graduation rate within four quarters, above the 2022 to 2023 lows and consistent with an improving but still below-average market (Incisive Ventures).
Seed-to-Series A graduation rates by cohort year
| Cohort | 2-year graduation rate | Source |
|---|---|---|
| 2018 | 30.6% | Incisive Ventures |
| 2022 | 15.4% | Incisive Ventures |
| 2024 (Q1-Q2, 4-quarter window) | 8.9% | Incisive Ventures |
Source: Incisive Ventures Update on Venture Graduation Rates, June 2025
Series A to Series B graduation follows a similar pattern. The 2018 cohort saw roughly 25% progress to Series B within two years. The 2022 cohort dropped to around 9%. Longer-term (four-plus year windows), 40 to 50% of Series A companies from 2018 to 2020 cohorts eventually raised a Series B.
The practical implication for founders is that reaching Series A has become significantly harder on a two-year horizon, even as the amount raised and the valuations at that stage have increased. Fewer companies make it through, but those that do are raising more.
For context on how this affects longer-term company survival, see startup failure rate statistics.
Share of startups that raise VC vs. bootstrap
Venture capital is the exception, not the norm. Approximately 0.05% of startups ever raise venture capital. The remaining 99.95% finance through bootstrapping, personal savings, credit, friends and family, or angel rounds that do not involve institutional VC (commonly cited across DemandSage, ChartMogul, and related research compilations).
Even among startups that do seek external capital, a meaningful share rely on angel investors or small seed funds rather than institutional VC firms with formal funds and LP capital.
Global VC investment grew from $118 billion in Q1 2024 to $126 billion in Q1 2025, but concentration is increasing. Roughly 60% of 2025 capital went to just 629 companies raising $100 million or more (Crunchbase). That concentration means the median VC-backed startup is competing against a market skewed heavily toward late-stage and AI mega-rounds.
How long does a funding round take to close?
Founders routinely underestimate how long a round takes. Seed rounds run 6 to 8 months from first investor contact to close, including roughly 2 months finding a lead and 3 months for due diligence. Series A rounds take 6 to 9 months including preparation time.
Bridge rounds with existing investors using convertible notes close faster, usually 30 to 60 days. Once a term sheet is signed, most rounds close within 30 days regardless of stage.
Series B timelines are longer because of the gap between rounds. The average total span from Series A close to Series B close is about 31 months, most of which is the time between when the last round was closed and when the new process started.
Running a full seed process while managing operations is one reason early-stage companies often underperform operationally during fundraising windows. The process is more time-consuming than most founders expect before they have done it.
Global VC dry powder and deployment
High levels of uncommitted capital have created a floor under venture market activity even during periods of reduced deal volume.
U.S. VC dry powder reached $307.8 billion entering 2025, meaning capital committed to VC funds but not yet deployed into companies (NVCA 2025 Yearbook). Global cumulative uncommitted VC capital was $652.2 billion as of the end of 2023 (PitchBook). European VC dry powder entered 2025 at $31 billion, the second-highest on record after 2022.
Broader private capital (private equity plus VC combined) stood at $2.1 trillion globally in 2024, down 11% year-over-year as deployment accelerated (McKinsey).
Despite the capital availability, deployment has been selective. The NVCA data shows that high dry powder has not translated into broad deal volume recovery - it has translated into larger rounds for qualifying companies.
VC deal volume trends (2024-2025)
Deal volumes in the U.S. recovered in 2024, and global activity jumped sharply in 2025.
United States (2024):
- 14,320 deals totaling $215.4 billion (NVCA 2025 Yearbook / PitchBook)
- Up from $162 to $209 billion in 2023, representing approximately 29% growth
- Nearly 30% of all completed U.S. investments went to AI companies (PitchBook-NVCA Q4 2024 Venture Monitor)
Global (2024):
- Total global VC investment: $368 billion (KPMG Venture Pulse 2024)
- Global deal activity fell 19% year-over-year to approximately 27,000 deals, the lowest since 2016 (CB Insights State of Venture 2024)
- AI represented 37% of venture funding and 17% of all deals in 2024, both all-time highs (CB Insights)
Global (2025):
- Venture and growth investors deployed $425 billion into more than 24,000 companies, up 30% year-over-year (Crunchbase 2025 annual report)
- 2025 was the third-highest venture financing year on record, behind only 2021 and 2022
- Approximately 50% of all global venture funding in 2025 went to AI-related companies (Crunchbase)
- Five companies alone - OpenAI, Scale AI, Anthropic, xAI, and Project Prometheus - raised $84 billion, representing 20% of all 2025 venture capital

AI has taken an increasing share of both deal count and dollars in each of the last three years. Founders in non-AI sectors are competing for a smaller portion of total capital than they were in 2021 and 2022.
Key takeaways for startup founders
A few things stand out from the current startup fundraising data compared to 2020 to 2022.
Valuations are up, but the qualifying bar is higher. Seed post-money valuations hit all-time highs in Q4 2025 while deal count fell 29%. Fewer companies are raising, and those that do command better terms.
Timelines are longer than founders tend to assume. The median seed-to-Series A interval is 774 days. 39% of seed-stage startups take three or more years to get there. Add 6 to 8 months for the seed process itself and founders are looking at 3+ years from first close to Series A - if they graduate at all.
Graduation rates have not recovered. Only 15.4% of 2022 seed cohort companies raised a Series A within two years. 2024 data shows some stabilization, but the rate has not returned to pre-2021 levels.
Capital is heavily concentrated. 60% of 2025 global VC went to 629 companies raising $100 million or more. The median VC-backed startup operates in a very different market than what the headline totals suggest.
Dilution compounds across rounds. With seed dilution around 19 to 20% and Series A at 18 to 20%, founders reaching Series B have typically sold 35 to 40% of the company already, before the Series B dilutes them further. How much equity founders hold at exit depends almost entirely on the number of rounds raised and the terms at each one.
