European VC Outperforms the US Over 20 Years. So Why Does Conviction Feel So Hard?

Start with the data most people get wrong. European VC 10-year net IRR: 20.77%. US VC 10-year net IRR: 18.18%. Over 20 years, European MOIC comes in at 2.4× against 2.11× for the US.

These are Cambridge Associates figures. They are not widely cited, because they contradict the conventional wisdom that European venture is structurally inferior to its American counterpart. They are also true.

So why, if European VC outperforms on a long-horizon basis, does building conviction feel so hard — and why are so many European investors still pricing deals without a real read on the technology they're backing?

Where the US does have an advantage

The long-run return picture is real, but it comes with caveats. US VC outperforms significantly on short-term rolling returns — in 2024, US VC funds returned +1.9% over trailing 12 months against –15.7% for European funds. LP payback speed: 4.5 years in the US versus 6.7 years in Europe.

The US also leads on capital scale. $209 billion invested in 2024 against Europe's $62.4 billion. In AI specifically, the gap is 10×. At the very top, the 10 largest US funds captured 33% of all capital raised; Europe's top 10 captured 17%.

And on deal speed, the divergence is structural: a US Series A closes in 6–12 weeks. A European Series A takes 4–6 months. A US term sheet in a hot deal is issued in 8 days or less. In Europe, weeks to months.

The conviction gap is the real story

European VCs must build confidence across a longer process with fewer real-time competitive signals. A Dutch Series A partner put it clearly in our research: 'By the time we've moved through our full process, we've already formed a view on price. The diligence that follows is largely confirmatory. If something materially changes, we're in an awkward negotiation with a founder we've already committed to emotionally.'

This is the conviction problem. European funds move slowly not because they're less decisive, but because the structure of their process — multi-jurisdictional legal complexity, formal IC cycles, absence of standardised term frameworks — makes it hard to build full conviction quickly.

The result: deals get confirmed, not discovered. The best returns come from being right about something early. European processes are optimised for thoroughness, not for early conviction.

The entry valuation advantage is real — but only if you can act on it

Here is the opportunity hiding in plain sight. US median seed valuations are more than 2× European equivalents. European B2B startups generate approximately 10% more value per invested capital than US counterparts when measured on enterprise value per euro deployed. US developer salaries are ~60% higher than European equivalents.

Europe has 5.7 million developers against 4.4 million in the US — more builders, at lower cost, building for a 450 million consumer market with fundamentally different regulatory and enterprise requirements than the US.

The fund that can move quickly on a European company with a compelling technical foundation, before the price reflects that reality, is the fund that captures the return advantage. The valuation entry advantage is real. But it only translates to outperformance if the fund can actually assess what they're backing — fast enough to act.

What closes the gap

Speed of conviction is the lever. Not speed of legal process — that's structural and unlikely to change. But speed of technical conviction: how quickly can a fund go from 'commercially interested' to 'we know what we're backing and we're prepared to pay for it'?

The funds closing this gap are building technical assessment into the front of their process, not the back. They're not running tech DD post-LOI as a confirmatory exercise. They're running it pre-LOI as a conviction-building tool — getting the same information faster, making the technical section of the IC memo credible, and moving to terms before competing funds have finished their first round of meetings.

Europe generates 17% of new global enterprise value. It captures only 10% of exit value. The gap between creation and capture is not inevitable. The funds that will close it are the ones that figure out how to move with American speed on European technical depth. That combination doesn't exist yet at scale. It's the opportunity.
