10 Most Active Venture Capital Firms in London 2023

Sarah Cheesman, Updated: 11 January 2024

London has been leading the way in European venture capital (VC) funding and entrepreneurship for many years now, even giving Silicon Valley a run for its money. Venture capital firms have pumped over £26b into the city’s startup ecosystem since 2011, from high-risk, pre-seed companies to more established ventures. Here, we’ve ranked the 10 most active venture capital funds in the capital, between 2011 and 2023, by number of investments made into London-based companies. Scroll down for full profiles on each fund, including investment criteria and some of the fast-growing businesses they’ve backed.

What are venture capital funds?

Venture capitalists are the most common equity investors in high-growth companies, ahead of both crowdfunding platforms and angel investors. VCs specialise in buying shares in and growing the valuations of private companies. But how does venture capital investment differ from other forms of startup funding? Unlike other institutional investors, many venture capitalists have been on the other side of the table, as founders of their own startups, so can offer their expertise and longer-term support, alongside growth finance.

Venture capital funds also typically invest in riskier portfolios than private equity and hedge funds, although each fund will have its own set of criteria outlining the types of investment opportunities considered. These decisions are made by fund managers (General Partners or GPs), whilst financial backing usually comes from large corporate investors or high-net-worth individuals (Limited Partners or LPs).

Venture capital in London’s startup ecosystem

Private equity and venture capital firms are very active investors in London startups and scaleups. Since 2011, 27% of equity deals secured by high-growth UK companies and backed by PE or VC firms have gone to businesses based in London. But that proportion is increasing, standing at 42% in 2022. Our data indicates that 619 funds have backed 3,366 equity investments in the region, providing growth capital to 3,016 high-growth businesses in London.

Unsurprisingly, venture capital investment in London predominantly goes to early-stage startups. Of the PE/VC funding rounds secured by high-growth companies in the capital, 70% have gone to either seed or venture-stage businesses. In comparison, only 21% of PE/VC investment has been raised by companies at the growth stage, and just 6% by those at the established stage.

Aside from a slight drop in 2018, VC activity in London has grown significantly over the past decade, from just 39 deals in 2012 to 634 in 2022. And despite—or potentially because of—the COVID-19 pandemic, we saw particularly strong growth in venture capital investment between 2020 and 2021, with a 42% rise in deal numbers.

This article looks at the most active venture capital funds in London, regardless of sector. If you want to narrow down these VCs even further, or by activity in other regions, then you can do so on the Beauhurst platform.
