What UK Angel Investors Look for in Startups

‍Introduction

Angel investors play a vital role in supporting early-stage startups, providing not just capital but also mentorship and strategic guidance. While each angel investor or syndicate may have unique investment theses, there are common factors that many look for when assessing a startup. These factors range from commercial traction and defensible technology to the quality of the founding team and the potential for a profitable exit. In this guide, we explore these key considerations in detail, offering insights into what startups need to demonstrate to attract angel investment.

Commercial Traction

One of the most critical factors angel investors consider is whether a startup has achieved any level of commercial traction. Investors want to see proof that there is a market for the product or service, ideally backed by revenue generation, user engagement, or other key performance indicators.

Some well-established angel syndicates, such as 24 Haymarket, focus on commercial traction over the potential of exciting new tech.

Defensible Intellectual Property and Technology

Other angel investors, like Ascension Syndicate and Cambridge Capital Group, focus on startups with strong intellectual property (IP) and proprietary technology. Often focusing on deep-tech and science-driven businesses, these investors prioritize startups where intellectual property forms a core part of the company’s value proposition. A ‘technology moat’ can provide  a long-term competitive advantage through patents, proprietary algorithms, or unique technological advancements.

Founding Team and Leadership

Beyond the business model and product, investors place a strong emphasis on the founding team. A great idea is only as good as the team executing it, and investors want to back entrepreneurs who have the experience, resilience, and skills to build a successful company.

Angel Academe, for example, specifically focuses on female-founded tech startups, reflecting the importance of founder diversity and expertise. Meanwhile, SFC Angel SEIS highlights the importance of founders who are - yes - ambitious and capable, but also flexible and able to take feedback from investors.

Regional Focus

Many angel investors and syndicates have specific geographic focuses. These tend to break down into either industry ‘clusters’, or regional development.

For example, Cambridge Capital Group focuses on startups within the UK’s "Golden Triangle" (Cambridge, Oxford, and London) - while Angels in MedCity focuses on London’s life sciences cluster.

Meanwhile, Par Equity in Edinburgh and GC Angels in Manchester concentrate on supporting regional innovation in the North of the UK.

Sector Focus

Some angel investors specialize in particular industries.

For example, Galvanise Capital specializes in MarTech and AdTech, while Green Angel Syndicate funds businesses in the cleantech and sustainability sectors, and Cambridge Angels focus on science and engineering, with a particular focus on healthcare tools and technology.

Social and Environmental Impact

With growing awareness of environmental and social challenges, many investors prioritize startups that deliver positive social or environmental impact. Groups such as Green Angel Syndicate focus on sustainability and cleantech investments, supporting startups that contribute to reducing carbon emissions, improving energy efficiency, or addressing other environmental concerns.

Who Else is Investing?

Some investors use other angels or funds to validate or 'derisk' opportunities. This can go both ways - sometimes angels look to managed funds to co-invest with; conversely there are also funds that specifically invest in companies that have managed to attract angel syndicates.

Angels Co-Investing with a Managed Fund: Some angel groups or syndicates, such as FSE Angel Group and SFC Angel Fund SEIS, focus on investments that align with their in-house managed funds. Startups benefit from increased investment, while angel investors leverage the expertise and strategic input of the fund.

Funds Co-Investing with Angel Syndicates: AngelCoFund co-invests in companies that are receiving investment from other angel syndicates. This ensures that the startups it invests in have already been vetted by other experienced investors. The angel group or syndicate does not have to be too formally established, although there are certain criteria to qualify - if you already have a group of angels onboard, it’s worth considering this option to maximise your fundraising.

Tax Relief

Many UK angel investors are strongly influenced by tax relief incentives such as the Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS). These government-backed schemes reduce the financial risk for investors, making eligible startups more attractive investment opportunities.

SEIS allows very early stage startups to raise up to £250,000 with 50% tax relief for investors, while EIS enables up to £5 million in funding per year with 30% tax relief, up to a lifetime limit of £12 million. Startups that qualify for these schemes should highlight their eligibility in their investment materials, as it can significantly enhance their ability to attract angel funding.

An exit strategy

Angel investors are ultimately looking for a return on their investment, often within five to ten years. A startup must have a clear and realistic exit strategy, whether through acquisition, a secondary share sale, or (less commonly) an IPO.

Acquisitions by larger companies are the most common exit route for angel-backed startups. Investors want to see that a startup is operating in an industry with active M&A activity and has a business model that will be attractive to potential buyers.

Some startups may offer secondary share sales as an earlier exit opportunity, allowing angels to sell their equity before a full acquisition. While IPOs are rare, they can be a potential exit for high-growth companies in scalable markets.

The key for founders is to articulate a well-thought-out exit plan that aligns with investor expectations and market trends.

Conclusion

Angel investors assess startups based on a combination of commercial viability, intellectual property, leadership strength, regional and sector focus, and potential for a profitable exit. While each investor may have different priorities, understanding these key factors can help founders position their businesses effectively and improve their chances of securing funding.

By demonstrating strong traction, a compelling value proposition, and a scalable business model, startups can attract the right angel investors who bring not only capital but also strategic support to fuel growth and long-term success.
