When a $2 Billion Seed Round Is Normal: Real Funding Data from 1,190 Startups
By Fast AI Startup Jobs
TL;DR
We verified the funding data of 1,190 startups currently hiring on our platform. The results show that traditional funding stage labels have become nearly meaningless: $2B seed rounds, $900M Series A rounds, and 40% of all early-stage funding going to $100M+ deals. Our data, combined with industry benchmarks from Carta and Crunchbase, reveals a market where a handful of AI-adjacent megadeals are distorting the entire venture landscape.
Our Data: Median Funding by Stage
We maintain verified funding data for 1,190 companies — all actively hiring, spanning Pre-Seed through Series G+. Here's what the numbers show:
| Stage | Companies | Median Round Size | Median Total Raised | Industry Benchmark* |
|---|---|---|---|---|
| Pre-Seed | 21 | $0.6M | $1.5M | ~$0.7M (Carta) |
| Seed | 191 | $6.1M | $7.5M | $3.1-4.0M (Carta/Pitchwise) |
| Series A | 443 | $20M | $28.1M | $12-15M (Crunchbase) |
| Series B | 201 | $50M | $85.4M | $38-40M (Pitchwise) |
| Series C | 109 | $100M | $200M | ~$80M (Pitchwise) |
| Series D | 49 | $130M | $375M | $96.5M (Pitchwise) |
| Series E | 20 | $260M | $759M | — |
| Series F | 7 | $300M | $958M | — |
*Industry benchmarks from Carta State of Private Markets 2025, Crunchbase H1 2024, Pitchwise 2026
Why our numbers are systematically higher: Our sample is biased toward AI and high-growth tech companies — the kind that are actively hiring. According to Pitchwise, AI/ML seed rounds carry a 1.3x premium over the broader market, and AI Series A valuations are 1.7x the overall median per Carta.
This isn't a flaw — it's a feature. If you're job-hunting at startups, these are the companies you'd actually work at.
The Mega-Seed Phenomenon
The most striking finding: "Seed" no longer means what you think it means.
Seed Rounds Over $100M in Our Database
| Company | Seed Amount | Date | Founder Background |
|---|---|---|---|
| Thinking Machines Lab | $2,000M | 2025-06 | Mira Murati (ex-OpenAI CTO) |
| AMI Labs | $1,030M | 2026-03 | Yann LeCun (ex-Meta Chief AI Scientist) |
| Humans& | $480M | 2026-01 | Ex-Anthropic, xAI, Google researchers |
| Unconventional AI | $475M | 2025-12 | Naveen Rao (ex-Databricks AI, sold Mosaic ML for $1.3B) |
| Periodic Labs | $300M | 2025-09 | — |
| Genesis AI | $105M | 2025-07 | — |
The pattern is unmistakable: "Seed" just means "first round." It says nothing about size, maturity, or product readiness.
As Crunchbase noted about Thinking Machines Lab's $2B seed:
"It's not even close. The next-largest U.S. seed financings have all been in the $200 million to $450 million range."
Investor Ashish Saboo called it:
"Expensive FOMO... beyond pre-revenue. It's pre-everything. Pure bet on human capital."
Series A: The New Hundred-Million-Dollar Club
Our data shows 17 companies that raised $100M+ Series A rounds:
| Company | Series A Amount | Date | Sector |
|---|---|---|---|
| Pacific Fusion | $900M | 2024-10 | Nuclear Fusion |
| Tempo | $500M | 2025-10 | Blockchain/Payments |
| Lila Sciences | $350M | 2025-10 | AI/Biotech |
| Ricursive Intelligence | $300M | 2026-01 | AI Chip Design |
| Liquid AI | $250M | 2024-12 | AI Infrastructure |
| Fundamental | $225M | 2026-02 | AI/Data Analytics |
| Upscale AI | $200M | 2026-01 | AI Infrastructure |
Pacific Fusion's $900M Series A used a milestone-based structure where funds unlock as the company hits targets — a structure borrowed from biotech. But critics noted:
"As soon as a milestone is missed (which is almost inevitable when working on challenging science and engineering), that will force revaluations and renegotiations. Therefore, any money beyond what is unlocked is not actually guaranteed."
Ricursive Intelligence went from $35M Seed to $300M Series A in just 2 months, reaching a $4B valuation four months after founding.
The 50/1 Rule: Half the Money, One Percent of the Companies
The most important number from 2025 venture capital:
"50% of all the venture capital raised in 2025 went to 1% of the companies." — Crunchbase Predicts 2026
In Q1 2026, this concentration intensified further. Crunchbase reported:
"Investors poured $300 billion into 6,000 startups globally in the quarter... AI shattered records, with $242 billion — 80% of total global venture funding — going to companies in the sector."
"Four of the five largest venture rounds ever recorded were closed in Q1 2026, with OpenAI ($122B), Anthropic ($30B), xAI ($20B) and Waymo ($16B) collectively raising $188 billion, or 65% of global venture investment in the quarter."
Our employee count data illustrates what this concentration means in practice:
| Stage | Most Common Employee Bucket | Second Most Common |
|---|---|---|
| Seed | 11-50 (60%) | 1-10 (39%) |
| Series A | 11-50 (67%) | 51-200 (25%) |
| Series B | 51-200 (60%) | 11-50 (27%) |
| Series C | 51-200 (43%) | 201-500 (39%) |
| Series D | 201-500 (43%) | 51-200 (31%) |
Translation: a typical Seed company is still a 15-person team — even when it has $475M in the bank.
The AI Distortion Field
According to Kruze Consulting citing PitchBook data:
"AI/ML deals captured 65.6% of all VC deal value in 2025 ($222B out of $339B), up from 47.2% in 2024 and just 10% in 2015."
Crunchbase's year-end analysis found:
"In AI, 58% of funding was in megarounds of $500 million or more."
"The two largest foundation companies, OpenAI and Anthropic, alone captured 14% of global venture investment this year."
What does this mean for non-AI startups? A Series A crunch is real. Axios reported:
"Only 15.5% of companies that raised seed funding in Q1 2023 had secured a Series A by Q1 2025."
"46% of all seed transactions in Q1 2025 were bridge rounds" — the highest proportion ever recorded by Carta.
What Stage Labels Actually Mean Now
Based on our data and external research, here's what the labels actually indicate in 2026:
| Label | What It Used To Mean | What It Means Now |
|---|---|---|
| Pre-Seed | Friends & family, $50K-$500K | Still mostly small, $0.6M median |
| Seed | First institutional check, $1-3M | First round of any size ($0.25M to $2B) |
| Series A | Product-market fit, $5-15M | Second round of any size ($0.25M to $900M) |
| Series B | Scale, $20-40M | Third round, roughly $50M median |
| Series C+ | Growth/pre-IPO | Actual growth stage, $100M+ |
As Crunchbase's Joanna Glasner put it:
"The stereotype of a round at this stage — a small, risky bet on an unproven founder — may need some updating."
What This Means for Job Seekers
If you're evaluating startup job offers, here's what our data suggests:
-
Funding amount alone tells you nothing about company maturity. A $500M "Seed" company might have 10 employees and no product. A $15M Series A company might have 100 employees and $10M ARR.
-
Look at employee count, not funding stage. Our data shows employee count is a far better indicator of company maturity than funding round labels.
-
The safest bet is Series B-C with 51-200+ employees. These companies have proven product-market fit AND have the capital to grow.
-
Be cautious with mega-funded early-stage companies. History shows that massive early funding doesn't guarantee success — Inflection AI raised $1.3B but was effectively acqui-hired by Microsoft within a year.
