Pre-seed funding is most accessible in London, and founders who understand the ecosystem here raise faster, smarter, and on better terms than those who approach it without a clear plan.
Why London is the right market for angel investment
London has more than 4,000 active angel investors and more than 150 organised networks. That concentration of capital is unmatched in Europe. London is Europe’s largest angel market. UK angels deployed over £2.5 billion into startups in 2024. For a first-time founder, this is the single most important fact: the capital is here, the infrastructure is here, and the appetite is real.
London accounts for 68% of all UK pre-seed deals. This concentration reflects the capital’s strong startup infrastructure and proximity to major venture capital firms. Furthermore, angel investors participate in 92% of pre-seed rounds. These numbers tell a clear story. If you want pre-seed funding, London angels are your primary audience, and you must treat them accordingly.
London pre-seed investors focus on the founding team, market opportunity, product vision, and early signs of traction. At this stage, investors often back potential and execution ability rather than financial performance. So arrive with evidence, not just an idea.
How SEIS and pre-seed funding work together
The two UK government tax schemes, SEIS and EIS, are not optional extras. They are the foundation of the London angel market. UK founders have a distinct advantage in their toolkit: government-backed tax relief schemes that reduce investment risk and unlock capital. The Seed Enterprise Investment Scheme (SEIS) and the Enterprise Investment Scheme (EIS) are powerful mechanisms to help you raise equity funding by making your startup more attractive to investors.
SEIS lets a qualifying company raise up to £250,000, with investors receiving 50% income tax relief on their investment. EIS covers larger raises and gives investors 30% income tax relief, plus capital gains advantages. For angels, these reliefs materially reduce the downside on a risky early bet, which is why many networks will only look at companies that qualify.
If you plan to raise under SEIS or EIS, obtain HMRC Advance Assurance before approaching investors. It is a formal confirmation from HMRC that your company is likely to qualify for the scheme. Many UK angels and angel syndicates treat this as a prerequisite. In the 2024 to 2025 tax year, HMRC received 3,195 SEIS advance assurance applications, with 2,705 approved: an 85% approval rate. Apply early and apply carefully.
Pre-seed funding networks worth targeting in London
Not every network suits every founder. Sector fit, stage fit, and check size all matter. One way to simplify the fundraising process is to go through an angel group or syndicate. Instead of pitching to individual investors one by one, these groups allow founders to pitch groups of investors at the same time, with the potential to save time and raise larger sums.
24 Haymarket, based in London, is a network of over 100 private investors with more than 3,000 years of collective investment and operational experience. They take an active approach to investing, often securing board seats in the startups they back. The group focuses on businesses that demonstrate commercial traction rather than prioritising deep tech or R&D. Angel Academe backs female-founded tech startups with over 400 active members. They invested in LabCycle in January 2026 and focus on medtech, cleantech, fintech, and enterprise software.
Ventures Together is made up of more than 150 top startup founders and operators in the UK. The group invests in 80 pre-seed and seed stage startups each year, the equivalent of 2 new startups every week. On average, Ventures Together invests between £50,000 and £250,000 in every pre-seed and seed round. Match each network to your sector and stage before you apply.
Expert perspective on what angels look for at pre-seed
Angel investors at the pre-seed stage are not buying a proven business. They are buying a founding team and a thesis. The question every investor asks is simple: do these founders understand the problem better than anyone else, and can they execute under pressure? Traction helps, but it is not the only signal. A clear, honest explanation of why this market exists, why now, and why this team is the right group to attack it is often more persuasive than an early revenue number. Founders who show they have spoken to 50 potential customers, understand objections, and have a structured plan to use the capital tend to close rounds faster than those who lead only with the size of the market opportunity. The pitch is also a test of judgment. Investors watch how founders respond to hard questions. Composure, intellectual honesty, and a willingness to say “I do not know yet, but here is how I will find out” build more trust than a polished answer to every question.

How to structure your pitch for pre-seed funding
A strong pitch does not begin with your product. It begins with the problem. Product-market fit signals matter more than revenue at pre-seed. Waitlists, letters of intent, pilot results, or beta user retention all count. Angels want evidence that customers need what you are building.
Cap table cleanliness is a quiet reason investors decline. Angels often pass on companies with messy equity structures, overvalued prior rounds, or founder vesting issues. Keep your legal house in order before your first meeting. Before you apply, prepare a tight deck of around 10 slides, a clear funding ask and use of funds, evidence of early traction however small, and your SEIS or EIS position confirmed.
Match the network to your stage and sector rather than approaching every group at once. A focused approach to 5 well-chosen networks beats 50 generic submissions, and it protects your reputation in a small market where investors talk to each other. London’s angel community is smaller than it appears. One poor approach circulates quickly.
How to get in front of angel investors
Access to pre-seed funding in London almost always starts with relationships, not applications. Cold applications through a website form work, but a warm introduction works far better. Map your network for anyone connected to a member, a portfolio founder, or the network manager, and ask for an introduction with a one-line reason it is relevant. Founders who have already raised from a network are often happy to refer good companies they are not competing with.
Founders often connect with London pre-seed investors through startup events, accelerators, founder communities, warm introductions, and direct outreach through LinkedIn or investor websites. UK angel networks and VC associates operate on warm introductions far more than cold outreach. Industry events, accelerator demo days, and sector-specific conferences are the most efficient ways to build the relationships that lead to funded conversations.
The UK Business Angels Association (UKBAA) is the leading trade association for angel and early-stage investment in the UK. It offers a strong network of investors and valuable resources for founders seeking investment, making it a useful starting point for accessing angel networks. Register with the UKBAA directory and use it as your map.
Closing your first pre-seed funding round
Pre-seed funding in London is genuinely available to founders who prepare properly and target the right people. Research shows that 67% of pre-seed funded startups successfully raise seed funding within 18 months. The momentum you build now shapes every subsequent round. Secure SEIS Advance Assurance, clean up your cap table, build a short and specific pitch, and approach networks that match your sector. Every conversation you have in the London angel market is also a signal about how you operate as a founder. Treat each one seriously.
Pre-seed funding is not a lottery in London. It is a process. Founders who follow a disciplined approach, use SEIS correctly, and target angels with genuine sector alignment close rounds. Start today, move with purpose, and close your pre-seed funding round on terms that give your startup the best possible foundation.
