Introduction
You’ve heard of SEIS. You’ve heard of EIS. But what do SEIS angel investors actually look for in UK startups? If you’re a founder, it’s not enough to have a great idea—you need to tick the right boxes. Think of angel investors as matchmakers who want to see evidence of potential, proof of traction and, above all, a clear path to a significant return.
In this guide, we’ll unpack the SEIS investor criteria, break down what truly attracts early-stage capital, and show you how to tailor your proposal. We’ll also spotlight how Oriel IPO’s commission-free platform and resources (like our AI-driven Maggie’s AutoBlog) can help polish your pitch and win support.
Understanding SEIS & EIS
Before diving into the SEIS investor criteria, it’s worth a quick refresher:
- SEIS (Seed Enterprise Investment Scheme)
- Tax relief of up to 50% on investments up to £100,000.
- Investors can exempt 50% of gains from income tax.
- EIS (Enterprise Investment Scheme)
- Up to 30% income tax relief on investments up to £1 million.
- Exemption from Capital Gains Tax on disposals after three years.
These schemes exist to de-risk early-stage funding. They draw angel investors by offering juicy tax incentives. But generous tax breaks alone won’t seal the deal. Investors still demand quality, growth potential and a great team.
Why SEIS Matters to Angel Investors
Angel investors are often high-net-worth individuals hunting for investments that outperform the stock market. The UK startup failure rate is famously high (up to 90% in 2019), so they need extra incentives. SEIS and EIS help soften that blow. But they also raise the bar:
- Risk cushion: Tax relief mitigates potential losses.
- Upside potential: Early equity stakes can skyrocket.
- Portfolio variety: Adds startup exposure alongside traditional assets.
Yet, schemes don’t override fundamentals. Investors will still screen every deal through their lens of SEIS investor criteria.
The Top SEIS Investor Criteria
When you pitch to a SEIS-savvy angel, they’ll look for these key factors. Nail them, and you stand a much better chance.
1. Clear Return on Investment
- Does the market gap exist?
- Can your product scale quickly?
- Are margins attractive?
Investors want high ROI. They’ll ask: “What’s the route to profit?” Show realistic financial projections, customer-acquisition costs and a timeline to breakeven. Use simple charts. Keep it punchy.
“A detailed forecast shows you’ve thought through revenue streams and burn rate.”
2. Strong, Trustworthy Management
- Founders’ track records.
- Domain expertise.
- Commitment and passion.
Angel investors back people as much as ideas. Demonstrate you’re a safe pair of hands. Briefly highlight each founder’s background. Inject a personal anecdote or two. It humanises the pitch.
3. Robust Business Plan
- Crisp executive summary.
- Clear marketing and sales strategy.
- Exit plan: trade sale, IPO or secondary buy-back.
A convincing business plan addresses both upside and risks. Include an exit strategy. That’s vital for SEIS investor criteria. They want to know how and when they’ll see returns.
4. Early Traction & Product/Market Fit
- Beta users, pilots or pre-orders.
- Positive customer testimonials.
- Press mentions or industry awards.
Early signs of traction are magic dust. They prove your concept works. Even a small trial run can impress. Collect feedback and embed quotes. It’s social proof.
5. Compliance & Eligibility
- SEIS/EIS compliance checklist.
- Qualified trades and UK-based operations.
- No connected-person issues.
If you don’t meet SEIS guidelines, investors can’t claim tax relief. It’s a non-starter. Show that your company structure, share classes and trading activities tick every box.
6. Quality Pitch Materials
- 10–20 slide deck.
- Clear visuals, minimal text.
- Demo video or live demo ready.
First impressions matter. Poorly designed slides or a cluttered deck can sink even the best idea. Tools like Oriel IPO’s Maggie’s AutoBlog help you generate SEO-optimised blog content, but the same attention to clarity and concision applies in pitch decks.
