The first proper money you raise. What it is, how much you can realistically get, and where to find it in the UK.
Who should read this: UK founders raising their first cheque, anyone weighing whether to bootstrap or raise, and founders trying to work out the difference between pre-seed, friends and family, and angel rounds.
Pre-seed funding is the first proper investment round a UK startup raises. Typically £100,000 to £500,000, sometimes more and sometimes much less. It buys you the runway to build a real product and find your first paying customers, before a seed round becomes possible.
If your savings are running out, your idea has more substance than a sketch on a napkin, and you're starting to wonder how other founders got their first money in, this guide is for you. It covers what pre-seed actually is, how much to raise, where UK money comes from, what investors look for, and the mistakes that kill rounds before they close.
The fastest way to understand pre-seed is to see how it differs from a seed round, which is what comes next.
| Pre-seed | Seed | |
|---|---|---|
| What it pays for | Building the product, validating demand, hiring first 1 to 3 people | Scaling what works, hiring a team, launching properly |
| Typical raise (UK, 2026) | £100k to £500k (about 45% of rounds raise less than £250k) | £500k to £3m |
| Typical valuation (UK, post-money) | £750k to £4m (varies widely with founder profile and sector) | £4m to £12m |
| Typical equity given up | 10% to 20% | 15% to 25% |
| Investor type | Angels, micro-VCs, accelerators, grants, friends and family | Angels, seed VCs, micro-VCs, sometimes corporates |
| What investors expect to see | Founder credibility, problem clarity, early customer signals, prototype or MVP | Working product, paying customers, repeatable acquisition channel, signs of product-market fit |
| Common instrument | Advance Subscription Agreements (ASAs) and SAFEs are dominant, plus convertible loan notes and occasional priced equity. ASAs are UK-native and tend to work cleanly with SEIS and EIS, which is why most UK lawyers default to them | Priced equity round with full term sheet, sometimes still ASAs or SAFEs at the smaller end |
| Typical round length | 3 to 6 months from start to close | 4 to 9 months |
The numbers above are typical ranges, not rules. Strong technical founders in obvious markets sometimes raise much more at much higher valuations. First-time founders in saturated markets often raise less. Treat these as a starting point, not a target.
"Pre-seed" became a distinct UK funding stage in the mid-2010s as round sizes drifted upwards and seed rounds got more competitive. Today most UK seed VCs expect a startup to have launched, hit some early traction, and have some kind of go-to-market hypothesis already proven before they'll write a cheque. Pre-seed is the round that gets you to that point: typically before meaningful revenue, often before a finished product, and almost always before you have the metrics a seed VC wants to see.
You'll hear three terms used loosely and sometimes interchangeably:
The lines between them blur. What matters is that the round gives you 12 to 24 months of runway to hit specific milestones that make your seed round possible.
The honest answer is: enough to get to your next funding milestone, plus a buffer for things going wrong.
The trap most first-time founders fall into is raising whatever they can rather than what they need. Either they raise too little and run out of runway six months in, or they raise too much and dilute themselves heavily for cash they can't deploy efficiently.
A useful starting framework:
Most UK pre-seed rounds in 2026 sit between £100,000 and £500,000. Sub-£100,000 rounds usually come from friends and family or a single angel. £500k to £1m rounds are happening more often, especially for AI and deep-tech companies, but they're still the exception.
Five sources, ordered roughly from smallest cheques to largest.
Cheapest money you'll ever raise, but also the most consequential to get wrong. Set clear expectations, document the investment properly (not on a handshake), and assume some chance the money is lost. This isn't pessimism, it's standard early-stage statistics.
Individual investors, often successful founders or operators, who write personal cheques. UK angels typically invest £10,000 to £100,000 per cheque, sometimes more for experienced angels in their domain. Angels are usually seeking SEIS or EIS tax relief, which makes SEIS and EIS advance assurance the single most useful piece of paperwork to have before pitching.
Active UK angel groups include Cambridge Angels (£150k to £1.5m total tickets, science and deep tech), Angel Academe (female-founded tech), and dozens of regional and sector-specific networks.
Structured programmes that combine cash, mentorship, and a peer cohort. They take equity in exchange. UK pre-seed accelerators worth knowing about:
Equity stakes vary from around 5% to 15% of the company depending on the programme. Read the accelerator guide for how to evaluate them.
A growing category of small UK funds that lead pre-seed cheques of £100,000 to £1,000,000. They move faster than larger seed funds and often invest with less traction. Names worth searching: Concept Ventures, Form Ventures, AENU, Ascension Ventures, plus the dozens of new £20m to £50m funds raised in the last two years.
Non-dilutive money. You keep your equity. Innovate UK competitions, local council innovation grants, and sector-specific programmes can deliver £25,000 to £250,000 without giving up a slice of the company. They're slower (3 to 5 months from application to decision) and very competitive, but they pair well with an equity round.

At seed stage, investors evaluate metrics. At pre-seed, they're evaluating you and your read of the problem, because there usually aren't enough metrics to mean much.
The five things that matter most, and how to actually show each one:
Notably absent: revenue, scale, polished metrics, a full team. Pre-seed investors expect you to be missing those. They're investing in the bet that you can build them with their money.
Two technical co-founders, both ex-employees of a known UK tech company, are building a B2B SaaS product. They have a working prototype, three letters of intent from potential customers, and 12 months of runway between them at break-even.
They want to:
Total target: £200,000.
They structure it as an Advance Subscription Agreement (ASA) with a £2m post-money valuation cap and a 20% discount, because their lawyer flagged that ASAs are the cleanest UK instrument for SEIS and EIS rounds. At conversion, that gives early investors roughly 10% of the company on the cap-rate scenario. Both founders have already filed for SEIS advance assurance, so the first £150k of the round qualifies for SEIS (within the company's £250k SEIS lifetime cap) and the rest goes through EIS.
They run the round over four months. Two angels write £50k each, an accelerator brings £75k plus support, and £25k comes from one of the LOI customers who decided they'd rather invest than wait.
These numbers are illustrative. Real rounds rarely close in exactly the structure they were planned. Valuations vary widely by sector and founder profile. Treat the example as a shape, not a target.
Pitching before you have advance assurance. UK angels expect SEIS or EIS eligibility. Without it you're asking them to bet they'll get the tax relief.
Raising too little. A £75k round that buys six months of runway puts you back in fundraising mode before you've shipped anything meaningful.
Raising too much. Overcapitalising at pre-seed dilutes you heavily and creates pressure to deploy capital you don't need yet. Bigger isn't always better.
Premature priced rounds. Setting a hard valuation at pre-seed locks in a number before you have data to defend it. SAFEs and convertible loan notes exist for this reason.
Pitching to seed investors. Most seed VCs filter aggressively. They want product-market fit signals you don't have yet. Spend your time with pre-seed-specific investors.
Skipping the legal foundations. Founder shareholder agreements, vesting, IP assignment, all need to be in order before you raise. See legal foundations.
Treating fundraising as a side project. Pre-seed rounds typically take three to six months of focused work. If you're trying to build the product and raise at the same time, expect both to suffer.
Roughly what running a pre-seed round looks like:
Some rounds close in six weeks. Some take nine months. Plan for the longer end, then be pleasantly surprised.
A founder who has SEIS or EIS advance assurance in hand before pitching, has a target list of 40 named investors who back their kind of company, knows exactly how the £200k or £500k will be spent, and can articulate in two sentences what the round buys them. Closes in three to four months. Raises just enough, not as much as possible.
