Britain’s startup scene has a quiet secret hiding in plain sight: a huge share of its most dynamic young companies were built by people who weren’t born here.

Whether an entrepreneur arrives on a visa, sets up a limited company from a rented desk in London, or runs a growing business from behind a UK virtual office address while still living abroad, migrants have become one of the biggest drivers of high-growth entrepreneurship in the country.

This isn’t a hunch. It’s backed by repeated, independently gathered data.

For anyone weighing up limited company formation in the UK, whether as a newcomer or a returning entrepreneur, the numbers below explain why the UK keeps ranking among the world’s most attractive places to launch a business, and why so many founders choose a UK virtual office as their first registered address before they’ve even found permanent premises.

What the data actually shows

The clearest evidence comes from The Entrepreneurs Network, a London-based think tank that has tracked immigrant participation in the UK’s fastest-growing companies since 2019. Their “Job Creators” research analyses the 100 UK businesses with the sharpest rise in valuation each year, drawing on investment data disclosed to Companies House.

The trend over time tells its own story:

• 2019: Nearly half of the UK’s fastest-growing startup companies (49%) had at least one immigrant co-founder, and nine of the UK’s 14 startup unicorns at the time had at least one foreign-born co-founder.
• 2024: The proportion eased to 39%, even though under 15% of UK residents are foreign-born, meaning immigrant founders remained hugely overrepresented relative to the general population.
• 2025: The figure jumped sharply, with 54 of the UK’s 100 fastest-growing companies found to have a foreign-born founder or co-founder, the highest proportion recorded since the research began. Among the 219 founders and co-founders behind that year’s cohort, 91 (42%) were born overseas.

That 2025 group breaks down further: 24 of the 54 immigrant-founded companies were built entirely by foreign-born teams, while the other 30 were joint ventures between British-born and immigrant co-founders, evidence the researchers say that migrant founders tend to complement domestic entrepreneurial talent rather than displace it.

The founders themselves come from a genuinely global spread of countries. In the 2023 cohort, they represented 28 nationalities across five continents, most commonly American, Italian, French, Canadian, Indian and German. By 2025, that had widened to 29 countries of origin, led by France, followed by the United States, Belgium, Germany and Italy. Household names with foreign-born founders or co-founders include Monzo, Deliveroo and DeepMind, alongside newer entrants like carwow and Atoa.

Why immigrants punch above their weight as founders

Researchers at The Entrepreneurs Network argue that migration itself selects for entrepreneurial traits: the decision to move countries requires risk tolerance and resilience, and outsiders are often quicker to spot gaps that longer-established residents overlook. The organisation’s research director, Eamonn Ives, has pointed to the disproportionate role foreign-born founders play at the top of Britain’s startup ecosystem, describing it as a case for keeping the UK welcoming toward global talent.

Individual founders echo the point. Teru Adachi, who relocated from Japan to launch cyber-risk platform Aprio Technologies in London in 2023, has praised the UK’s diverse, innovation-friendly business culture, while also noting that the visa system still feels better suited to large companies than to nimble, early-stage firms.

The practical route in: visas and company formation

For a migrant entrepreneur, building a UK business generally involves two separate but related processes: securing the right to work and run a business here, and legally registering the company itself.

Immigration route. The main dedicated pathway is the Innovator Founder visa, which replaced the older Innovator and Start-up visa routes. According to GOV.UK, applicants need a business idea that has been assessed and endorsed by an approved endorsing body, and must meet the English language requirement, be at least 18, and show they have enough personal savings to support themselves while in the UK. Holders can run one or more businesses, work as a director or self-employed partner, and take on additional skilled work outside the business. There is no longer a fixed minimum investment requirement; applicants instead need to demonstrate that their business plan is genuinely innovative, viable and scalable.

Company formation route. Separately, and regardless of visa status, anyone can register a UK limited company. The Companies Act 2006 places no nationality or residency restriction on directors or shareholders, so a founder can be the sole director and sole shareholder of a UK company without ever living in the country. The one fixed requirement is that the company itself must have a UK registered office address: a physical address in the same part of the UK where the company is incorporated, used for statutory correspondence from Companies House and HMRC. This is why many overseas founders use a UK virtual office or a commercial registered office address service rather than list a home address abroad, particularly since directors must now also complete identity verification with Companies House.

In practice, the process tends to look something like this: choose a unique company name, appoint at least one director and shareholder, provide a registered office address (often a virtual office address bought as a standalone service), and file the incorporation documents with Companies House. A company such as BusinAssist, for example, could be incorporated entirely online by a founder based overseas, using a UK virtual office address for its registered office while the founder continues operating remotely or applies for the appropriate visa to relocate.

A widening gap and a policy question

The jump from 39% to 54% between the 2024 and 2025 Job Creators reports is the sharpest single-year swing the research has recorded, and it has reignited debate over UK immigration and visa policy. The Entrepreneurs Network has previously called for reforms including a Youth Mobility Scheme with the EU and US, lower visa fees for highly skilled applicants, and a broader High Potential Individual visa scheme, arguments made on the basis that, without foreign-born founders, the economy would be measurably less dynamic and tax revenues smaller.

Whatever the policy debate concludes, the underlying pattern in the data has held for six years running: immigrant entrepreneurs are consistently overrepresented among the UK’s highest-growth companies relative to their share of the population. For anyone considering where to build a startup, the UK’s mix of open company law, straightforward limited company formation, and a well-established market for UK virtual office and registered office services continues to make it one of the more accessible places in the world to go from business idea to incorporated company — even before the visa paperwork is finished.
