The UK tech scene is one of the best supported startup ecosystems in the world, attracting billions of pounds of venture capital through hundreds of funding rounds each quarter, and nurtured through world-class accelerators, incubators and government measures. But it’s not just specialist organisations that are helping to drive innovation. Hundreds of high-net-worth-individuals are supporting the ecosystem through angel investing, and drawing on their own expertise to mentor the next generation of tech founders.
Here, we’ve identified the people who own shareholdings in more than 30 UK tech companies, many of whom are entrepreneurs as well as investors. We’ve excluded those who invest over 85% via crowdfunding platforms (as they’re less likely to have their own deal flow, instead relying on friends and family for the remaining 15%), as well as those who have a limited public profile.
We’ve drawn on Beauhurst data on shareholdings, accessible through our Networks feature, as well as social media and other publicly available channels, in order to build a picture of each of these entrepreneurs and business angels. These profiles are ranked by the number of shareholdings in private UK tech companies that each person currently holds, and includes details on the investor networks they’re part of, and some of the early-stage startups they’ve founded and backed.
It’s expected that the biggest stakeholders in any industry will have built up their portfolios over years of investing, informed by decades-long careers (to develop a sector specialism), large networks (in order to build deal flow) and personal wealth (in order to invest).
As the industry starts to address the structural biases and barriers facing women and minorities, and encourages a more diverse pool of investors, we hope (and indeed optimistically expect) that we’ll see people from a broad range of backgrounds featuring on lists like these.
