Angel investors are an important fundraising source for early-stage companies, particularly those that are yet to secure investment from private equity and venture capital firms. And many of the UK’s most active angels and biggest stakeholders are former entrepreneurs themselves. These founders turned angels are a crucial part of our maturing startup landscape, even after exiting their businesses.

The UK’s high-growth ecosystem certainly has a plentiful supply of investment opportunities for high-net-worth individuals.
