A look at a cluster of European cities within a five-hour train ride of London that collectively have 500+ startups with at least $100M of annual revenue
A cluster of European cities within a five-hour train ride of London could become a unicorn factory to rival Silicon Valley, argues tech investor Saul Klein.
Context & Ripple Effects
The case for a cross-border growth corridor builds on Dealroom’s finding that the UK had far more startups above $25M in annual revenue than France or Germany as of May 2024, a revenue-based measure of Europe’s startup depth. The new lens raises the threshold and treats proximity to London as an economic network rather than a single-city contest.
It also reframes a longstanding European concern: earlier coverage focused on Europe’s difficulty producing globally dominant tech companies, while later investor commentary argued that experienced founders and larger risk appetites are needed to create category-defining firms.
First-order effects
- The cities and companies in the corridor gain a common scale narrative centered on established revenue, giving investors and prospective hires a clearer way to compare the region with more concentrated tech ecosystems.
- London’s role shifts from a national hub to a potential connective node for nearby European growth companies, broadening the set of businesses that can benefit from its capital and talent networks.
Second-order effects
- Investors may assess opportunities across the corridor rather than allocating by country alone, increasing competitive pressure on individual hubs to retain later-stage founders and high-growth companies.
- The emphasis on companies already at substantial revenue makes the gap identified in calls for more audacious European capital more concrete: financing and support must extend beyond company formation to scaling.
Third-order effects
- If cross-border networks repeatedly produce large-revenue companies, Europe’s startup ecosystem could be measured less by local unicorn counts and more by interoperable corridors that share capital, customers and senior talent.
- That outcome is not assured: the corridor thesis addresses company density, but the related coverage still points to the unresolved challenge of converting that base into enduring global technology leaders.
The trend: European tech is increasingly being judged by connected regional pools of scaled companies rather than by any one city’s startup count.
