Worked Dilution Example: Pre-Seed Through Series A
The table below shows how founder ownership erodes across a typical three-round journey. These numbers assume market-rate terms — each round is negotiable, and better terms compound significantly.
| Round | Founders | Investors | Option Pool |
|---|---|---|---|
| Founding | 100.0% | — | — |
| Pre-Seed SAFE (£200K at £2M post) | 89.5% | 10.0% (SAFE) | — |
| Seed (£750K at £3M pre) | 64.2% | 28.1% (seed + SAFE converted) | 10.0% (created pre-round) |
| Series A (£5M at £12M pre) | 47.2% | 44.7% (all classes) | 8.1% (remaining ungranted) |
Note: Option pool created before seed round closes — this is the option pool shuffle, and it dilutes founders not investors.
UK-Specific Programmes
UK founders have access to non-dilutive and tax-advantaged funding that US founders do not. Use them. They do not replace equity fundraising — they reduce how much you need to raise and therefore how much you dilute.
Innovate UK Smart Grants
Grant (non-dilutive)Amount
£25K – £2M+
Best Used At
Pre-seed through Series A
Competitive grants for innovation projects. No equity given up. Cash goes to R&D. Application process takes 3–6 months — apply in parallel with fundraising, not instead of it.
British Business Bank (Future Fund successor)
Convertible loan / co-investmentAmount
Varies by programme
Best Used At
Seed through Series B
Multiple BBB programmes including managed funds and regional investment. Check the BBB programme finder — UK geography and sector affect eligibility.
R&D Tax Credits (RDEC / SME scheme)
Tax relief (non-dilutive)Amount
Up to 27p per £1 of qualifying R&D spend
Best Used At
Any stage
If your startup does qualifying R&D, you can claim cash back from HMRC. Loss-making companies can receive a cash payment rather than a tax reduction. Often overlooked by early-stage founders.
SEIS / EIS
Investor tax reliefAmount
SEIS: up to £250K | EIS: up to £12M
Best Used At
Pre-seed and seed (SEIS); seed through growth (EIS)
Not a grant to you — a tax incentive for investors. But it effectively reduces the risk of investing in your company, making it easier to raise from UK angels.

Do I need revenue for a seed round?
In the UK in 2024–2025, most seed investors want to see at least some evidence of demand — but not necessarily revenue. Strong pre-launch waitlists, letters of intent from potential customers, or very early paying pilots can substitute for revenue at seed stage. Pure pre-revenue seed rounds are still possible for exceptional teams in large markets, but they are significantly harder than they were in 2021–2022.
How much equity should I give up per round?
A rough target is no more than 20–25% per institutional round, and no more than 10–15% on pre-seed angel/SAFE money. The cumulative dilution across pre-seed, seed, and Series A typically leaves founders with 45–65% at Series A close. If you are significantly below 45% after Series A, you may struggle to attract Series B investors who want founder-led companies with aligned incentives.
What is a typical Series A valuation multiple?
Series A valuations in the UK are typically based on a revenue multiple — commonly 8x–15x ARR for SaaS businesses at growth stage in 2024. High-growth companies with 150%+ YoY ARR growth and strong retention can command higher multiples. Pure pre-revenue Series As are uncommon and typically require a strategic or market-timing argument rather than a financial one.
When should I raise vs bootstrap?
Bootstrapping is underrated for businesses that can become profitable early — services, marketplaces, and niche SaaS. Raise when: (1) the market requires speed and capital to win, (2) you need to hire before you can generate revenue, or (3) SEIS/EIS makes the angel round cheap enough to take without giving up meaningful control. Avoid raising out of desperation or because it feels like validation — the terms of a distressed raise are almost always punishing.
