Y Combinator (YC) is the world’s most selective startup accelerator. It serves as a powerful signal of global momentum. Since its founding, hundreds of European startups have joined its ranks.
We analyzed all 5,690 YC-funded companies, breaking them down by geography, sector, and cohort since 2014. These numbers highlight Europe's rise as a tech powerhouse and the fierce global competition it faces.
While the European ecosystem is far too vast to be defined by a single accelerator, YC provides a unique lens into which founders are building globally competitive companies. Here is what that data reveals about Europe’s top startups and the sectors they are transforming.
It is one signal. Here's what it shows about Europe's best startups, where they come from, and what they build.
Europe's Startup Map Is No Longer Just London
For years, "European tech" was shorthand for "London tech." In 2017, the UK accounted for 62% of all European YC companies. France, Germany, and the Nordics were barely on the radar.
That changed fast.
By 2019, Continental Europe permanently overtook the UK as the primary source of European YC companies. In recent years, the majority have come from outside Britain, from Paris, Berlin, Copenhagen, Barcelona, Zurich, and a dozen smaller cities. The crossover wasn't a blip. It never reversed.
The animated map below tells the story better than any chart. Watch how Europe's startup geography transforms year by year:
The number of countries sending companies to YC exploded from 4 in 2014 to 22 in 2021. Countries like Switzerland, Finland, Romania, Croatia, and even Georgia had their first YC companies. Eight nations entered YC for the first time in 2021 alone.
This is what ecosystem maturation looks like. It's not about one city getting stronger. It's about an entire continent developing the infrastructure, talent, and ambition to produce globally competitive startups.
The top senders today: UK (164 all-time), France (63), Germany (59), Spain (16), Denmark (14), Netherlands (13), Switzerland and Sweden (11 each). Germany sent more companies per year than France in 2022 and 2023, a shift that would have been unthinkable a few years earlier.
What's driving the geographic spread? A combination of factors: local accelerators like Entrepreneur First, Seedcamp, and Station F maturing into credible launchpads. Early-stage capital deepening in Paris, Berlin, and the Nordics. And a growing generation of founders who proved you don't need to be in London or San Francisco to build a globally competitive company.
Here's where the data gets interesting, and potentially misleading.
While Europe diversified geographically, its share of each YC batch appears to tell a different story. European companies peaked at 13.1% of YC's batch in 2021 — a record 95 companies. By 2025, that share had dropped to 5.5%.
At first glance, this looks like a decline. Global batch sizes stayed large — 631 companies in 2025 versus 727 in 2021 — but Europe's absolute numbers dropped from 95 to 35. Something is happening to European founders at YC. But probably not what the chart suggests.
COVID didn't inflate European numbers. It revealed them.
During 2020 and 2021, YC ran fully remote batches. European founders could participate without relocating to the US. They stayed in London, Berlin, or Paris, kept their European HQ address, and showed up in the data as European companies. The application process, the interviews, the selection bar, none of that changed. The only thing that changed was the visa requirement.
What 2021 likely shows is the real demand: remove the relocation barrier, and European participation jumps to 13% of the batch.
When YC returned to in-person batches and resumed expecting founders to move to San Francisco, the dynamic reversed. European founders who still wanted YC now had to relocate — and many incorporated a US entity to do so. A founder from Berlin who sets up a Delaware C-corp and lists San Francisco as their address shows up as an American company in the data. The European founder didn't disappear. They just became invisible in headquarters-based classification.
Consider the math: if the true European participation rate is closer to 13% than 5.5%, around 47 European-origin founders in the 2025 batch would be hidden behind US addresses. Is that plausible? YC actively encourages Delaware incorporation. It expects founders to relocate to SF. Around 15% of European founders have already moved their HQ to the US, and that's the baseline rate across all European startups. Among YC founders, who are literally told to move, the rate is almost certainly much higher.
The post-2021 "decline" is likely not a decline at all. It's a change in where founders file paperwork.
Other factors shaping the picture
Mature local alternatives. European accelerators and early-stage funds (Entrepreneur First, Seedcamp, Station F) have improved dramatically. The calculus of "uproot your life for 3 months in San Francisco" became less obvious when a strong local pre-seed fund can write a comparable check without the visa friction. Some European founders who would have applied to YC now have credible local options, though this represents ecosystem strength, not weakness.
YC's focus shift toward AI, but is Europe really behind? The accelerator leaned heavily into AI from 2023 onward, and the data shows European AI startups remain underrepresented at YC. But this is where the numbers may be misleading. Europe — and Switzerland in particular — has some of the highest AI research density in the world. European universities produce world-class talent that OpenAI, Anthropic, and Google DeepMind actively recruit from. VC capital is flowing into European AI. The data says one thing; the experience on the ground says another. This is a blind spot worth
investigating further, and one we plan to dig into in a follow-up analysis.
The real question isn't "why are fewer European startups getting into YC?" It's: "how many European founders are at YC right now, just listed under a San Francisco address?" Without founder nationality data (which YC doesn't publicly provide) we can't answer that definitively. But the evidence strongly suggests Europe's YC pipeline is more stable than the headline numbers imply.
What European Founders Actually Build: The B2B Pivot
The final lens: sector data reveals a dramatic shift in what European YC founders work on and it aligns with a broader trend across European startup fundraising.
Between 2014 and 2018, a third (33%) of European YC companies were consumer startups: marketplaces, social apps, direct-to-consumer brands. B2B software was 37%.
By 2022–2025, consumer had collapsed to just 4%. B2B/SaaS surged to 67%.
This wasn't just European founders chasing trends. The data backs it up: consumer companies have a 32% failure rate in our dataset, compared to 14% for B2B. Healthcare (5%) and fintech (8%) are the most resilient sectors.
What stands out in the sector data
Developer tools and open source are distinctly European plays — think PostHog, Gitpod, Cal.com. European engineering culture, with its emphasis on quality and reliability, translates well into infrastructure products.
Climate tech had a moment in 2021 (five climate and energy companies in a single batch) but didn't sustain into later cohorts, despite climate tech now representing 5.8% of European VC portfolios. The YC pipeline may not reflect the full picture here.
AI is the fastest-growing category at YC overall, but remains underrepresented among European YC companies. In European VC portfolios, AI represents 4.4% of companies. However, this likely understates the reality as Europe's AI research ecosystem is deep (ETH Zurich, EPFL, Oxford, Cambridge, TU Munich, and dozens of others are global leaders), and many European AI founders may be staying local or incorporating in the US. This deserves its own analysis.
Fintech steadily grew from 3% to over 10% — driven by UK and French companies tackling cross-border payments and financial infrastructure. This tracks with fintech being the second-largest sector in European VC portfolios (13.8%).
What This Means for European Founders and Investors
To be clear: YC acceptance is one data point. It doesn't tell us how strong the European startup ecosystem is. That picture requires funding data, exit outcomes, talent flows, revenue growth, and a dozen other signals. What YC data does well is reveal patterns in the kind of founders who compete at the global top tier, and how those patterns are shifting.
With that framing, here's what stands out:
Geographic maturation. Europe is no longer a one-city, one-country story. Startups from over 20 countries have participated in YC, and the infrastructure — from accelerators to early-stage capital — is deeper than ever.
The measurement problem. Europe's visible share of YC batches dropped from 13% to 5.5% — but the 2021 remote era likely revealed the true European participation rate, not an inflated one. The post-2021 decline is largely a measurement artifact: European founders are still getting in, they're just incorporating in Delaware and showing up as American companies. The talent pipeline may be stable or growing — just increasingly invisible.
Sector pragmatism. European founders have pivoted hard toward B2B software, developer tools, and fintech — high-survival, high-retention businesses. The consumer startup era is over. What replaced it is arguably more sustainable, even if it makes for less exciting headlines.
Where we see follow-up potential. This analysis raises as many questions as it answers — and we think that's a feature, not a bug. Specifically, we want to dig deeper into: the true number of European-origin founders behind US addresses, whether Europe's AI ecosystem is as underrepresented as the YC data suggests (we suspect not), and how the YC signal compares to European VC portfolio composition. If you have data, perspectives, or founder stories that could sharpen this picture, we'd love to hear from you.
A Note on Methodology And What This Data Doesn't Capture
This analysis classifies companies as "European" based on their headquarters country as listed in YC's public company directory. We define Europe broadly to include the EU, EEA, UK, Switzerland, and adjacent states (Turkey, Georgia, Ukraine). That's the only geographic data YC provides at scale.
This creates a significant blind spot: European founders who incorporate in the US are counted as American companies. Given that YC increasingly expects (or strongly encourages) founders to relocate to the US, and given that around 15% of European founders have already moved their HQ abroad — with the US as the dominant destination — the true number of European-origin founders in YC is almost certainly higher than 402.
A few specific patterns this data misses:
Delaware incorporation. Many European founders incorporate a US entity before or during YC. If they list San Francisco or New York as their HQ, they appear as American in this dataset. This effect is likely strongest post-2021, when YC returned to in-person batches and relocation became the expectation again.
The COVID variable. The 2021 peak (13.1% European share) coincides exactly with YC's remote batch era. European founders could participate without relocating, so they kept European addresses. Post-COVID, the same founders would incorporate in the US before applying. The apparent "decline" from 13.1% to 5.5% may partially reflect a change in where founders incorporate, not a change in how many European founders YC accepts. As discussed in Section 2, this makes 2021 a potentially important reference point — but one that requires further investigation with founder-level data to confirm.
Dual headquarters. Companies with offices in both London and San Francisco may be classified differently depending on which address YC records.
Post-YC relocation. Founders who were European at the time of YC but later moved their HQ to the US are captured as European in the batch year — but some datasets may update retroactively.
We're exploring ways to enrich this data with founder background information for a follow-up analysis. If you have suggestions or data sources, we'd love to hear from you.
