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

What is an Angel Investor?

Angel investors (or business angels, as they’re sometimes called) are high-net-worth individuals or sophisticated investors who look for opportunities to invest their money in startups and high-growth businesses. They hail from a wide variety of backgrounds. They are men and women of all ages. They could be a retired executive, a wealthy sports person, or indeed a fellow entrepreneur.

It varies of course, but Angel investors will typically look to take between 20% and 50% stake in your startup in return for the investment. They will often use your company’s valuation as a measure for what stake they should request. Angel investors 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. 

An Angel investor network is a collective of Angel investors who club together to 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.

To help you get a sense of what’s on offer, here are 22 of the UK’s most active and highest-performing Angel investor networks.

London-Based Angel Investment Networks

London is a thriving business and technology hub. Here’s a list of a number of Angel investor networks which have emerged to support the capital’s ambitious startups.

24 Haymarket

The team at 24 Haymarket typically invests in disruptive companies in the healthcare, industrial, consumer, technology and media industries. Recent investments range between £1M and £5M.

Angels in MedCity

With a strong focus on diagnostics, digital health and medical device technologies, Angels in MedCity bring investors together with life sciences entrepreneurs and startups. It was launched in 2014, and has since helped 43 healthcare and life sciences companies raise £14M.

Firestartr funds promising digital startups, helping them from the seed stage to Series A and beyond. The Firestartr Spark Series has become one of the leading tech events in London, facilitating high-level networking and covering topics such as blockchain and AI. Firestartr’s Angel investors invest up to $2M, with an average investment of around $100K.


Galvanise provides investment to early-stage tech businesses, typically focusing on startups in the marketing technology, advertising technology and data/analytics space. It usually invests between £150K and £1M.


Newable, which acquired London Business Angels in 2017, links Angel investors with startups across the UK. It specialises in knowledge-intensive companies, including those operating at the forefront of AI, 4IR, robotics and fintech. It services around 1,500 companies annually. The network typically invests between £250K and £2.5M.


Seedrs is an equity crowdfunding platform which has facilitated over £640M into over 800 deals on our platform across 19 different sectors. So it makes sense to start off by taking a look at the way Seedrs support the growth of early-stage businesses. 

With an estimated 330,000 Angels (in 2017) in active operation within the European Union, ranging from high net-worth individuals to syndicates and groups; knowing where to start, how to get in touch, and with who, is a massive challenge.

Seedrs launched the Anchor Investor Service and Deal Room specifically, for this reason, to amplify distribution by providing access to Angel Networks that regularly use the platform.  

Typically, finding Angels is a time-intensive process, even if everything goes smoothly, using Seedrs allows you to reach a wider audience with less effort. 

If you do find investors directly, even executing the round can be time-consuming. That’s why Seedrs also offers private deal execution, to relieve the administrative burden by leveraging Seedrs’ back-office functions to execute deals privately, allowing you to spend more time on what matters.

Angels typically invest between £10k and £50k of personal money, with the average Angel investor investing a median of £25k (according to the UKBAA). Often angel investors alone will be unlikely to fill your entire round, so you’ll need to work out how you can bookbuild to fill the round.

Seedrs are experts in book-building from multiple sources, giving you fast access to capital from a diverse group of investors by combining one of the world’s largest investment communities alongside angel investors, VCs, customers, family and friends. 

Wild Blue Cohort

Wild Blue is especially interested in entrepreneurs and startups with a link to the West London area.

A Crucial Cog In The System 

Because many Angel investors are ex-entrepreneurs or business leaders, they provide an essential value-add that makes Angel investment worth so much more than just the money. 

Look for those experienced in your sector, as their experience and advice are invaluable. You should also look for an ability to follow on, providing more later-stage capital to continue to support you through funding rounds.
