🏙️ Intro: Why London?

London has emerged as Europe's undisputed tech capital, with over £11 billion raised in 2024 and a thriving ecosystem of 50,000+ tech workers concentrated around Silicon Roundabout alone. Whether you're relocating from San Francisco/Bengaluru, building your first startup, or scaling to Series B, this guide provides everything you need to navigate London's tech scene.

📊 The numbers speak for themselves.

• London remains the tech capital of Europe
• [The leading country in Europe, the U.K., represented around a third of funding to Europe's startups in 2024, with U.K.-based startups raising around $17 billion of the total funding.](https://news.crunchbase.com/venture/europe-startup-funding-eoy-2024/#:~:text=UK%2C France and Germany lead. The leading,in a close third with $7.6 billion.)
• The UK has 93 tech unicorns, the highest in Europe (October, 2025) </aside>

The city offers unique advantages: proximity to European markets, strong fintech and AI sectors, and a deep pool of engineering talent from world-class universities. To appreciate London’s strength you have to see what it’s being measured against.

In the U.S., especially San Francisco:

• Unicorn counts are higher
• But survival rates fade. For instance, half of U.S. businesses don't make it past five years.
• Also, many U.S. startups are optimised for rapid scale and exit, which can lead to fragility: when markets shift, when funding tightens, companies need to pivot or perish.

London may have fewer “supercharged” exits, but companies that do well tend to be more stable, often with diversified markets (both within the EU, UK, globally), more conservative scaling, more regulatory oversight, and often more enduring customer relationships.

Of course, London isn’t perfect. Some challenges include:

• Funding in certain hyper-growth stages may still lag behind the very largest U.S. rounds.
