Angel investors have emerged as an important source of funding for early-stage startups across the UK and Angel investor networks are helping to power the country’s economy, providing essential fuel for young, innovative companies who are creating new services, products and jobs.

In this article, we’ll cover what Angel investor networks are, how they help entrepreneurs and give you a list of active Angel investor networks across the UK in 2023.

What is Angel investor networks?

An Angel investor network is a group of high-net-worth or sophisticated individual investors who pool their resources to invest in startups and high-growth businesses, typically in exchange for equity in the company.

Angel investors are men and women of all ages hailing from a wide variety of backgrounds. They differ from other investors (for example, stock market investors) in that they often offer their relevant skills and experience to help you improve your startup’s performance and prospects. Angel investors typically look to take between 20% and 50% stake in your startup often using your startup’s valuation as a measure.

As a collective, Angel investors can network, share introductions and often syndicate their capital into a larger pot to make larger investments. Think of it as an alternative to a venture capital (VC) fund. Less corporate and more diverse, more personal.

Angel investor networks often focus on a specific industry or sector, or on seed- or later-stage investments, so finding the right one for your startup can increase your chances of finding suitable investors. Look for Angel investors experienced in your sector, as their experience and advice can be invaluable. You should also look for an ability to follow on, providing more later-stage capital to continue to support you through funding rounds.

To help you with your search, here are 25 of the UK’s most active and highest-performing Angel investor networks in 2023.
