Introduction
If you’re a founder on the hunt for cash, you’ve probably heard of UK SEIS angel investors. They’re the high-net-worth folks who back early-stage ventures under the Seed Enterprise Investment Scheme. Why? For tasty tax relief and the thrill of backing tomorrow’s unicorn. But what exactly do these startup angel investors look for? And how does Oriel IPO—our commission-free, curated, SEIS/EIS marketplace—help you tick all the boxes?
In this guide, we’ll cover:
- What SEIS means for angels and startups
- The top criteria startup angel investors assess
- How to compare Oriel IPO with other platforms
- Practical tips to boost your appeal
- And why Oriel IPO is your secret weapon
Let’s dive in.
Quick SEIS/EIS Refresher
Before we dissect investor minds, let’s rewind. The UK’s Seed Enterprise Investment Scheme (SEIS) offers:
- 50% income tax relief on investments up to £100k per tax year
- Capital Gains Tax exemption on successful exits
- Loss relief if things go south
Combine that with the Enterprise Investment Scheme (EIS) for later rounds, and you’re currying favour with startup angel investors who love a tax-efficient play.
Who Are Startup Angel Investors?
Startup angel investors are individuals deploying private funds into early-stage companies. They juggle higher risk for potential high returns. Often they bring more than cash:
- Mentorship
- Industry contacts
- Strategic advice
Think of them as a wise, well-funded uncle who’s picky about where his money goes.
Key Criteria UK SEIS Angel Investors Evaluate
Let’s break down what gets ticked in their due-diligence checklists.
1. Founder/Problem Fit
Angels bet on people, not ideas. They ask:
- Does this team have domain know-how?
- Are they complementary—tech whiz, biz dev guru, marketing ace?
- Do they live and breathe the problem they’re solving?
Founders who’ve scraped knuckles on the shop floor often stand out. They get the nitty-gritty. That instinct? Pure gold for startup angel investors.
2. Market Opportunity
Size matters. Angels want evidence that:
- The total addressable market (TAM) is big enough for 10× returns
- The segment is growing, not shrinking
- You’ve pinpointed a gap—preferably one you control
A niche can work if you dominate it. But vague promises of “revolutionising everything” won’t cut it. Data. Real numbers. Trends.
3. Early Traction
Show, don’t tell. Investors want proof you’re not peddling pipe dreams:
- User numbers or pre-orders
- Letters of intent from big clients
- Press or analyst mentions
No traction? Focus on pilot programmes or technical demos. Even a handful of paying users can silence sceptics.
4. Solid Business Plan & Financials
Yes, angels are risk-takers. But they still crave clarity:
- Revenue model and pricing strategy
- Burn rate and runway
- Clear ask: “I need £X to hit Y milestones”
- Exit plan (IPO, acquisition, secondary sale)
A lean, plausible roadmap instils confidence. Vague spreadsheets? Not so much.
5. SEIS/EIS Tax Incentives
You’re pitching to SEIS-savvy investors. Spell out:
- Tax relief percentages
- How long shares must be held
- Any caps or exclusions
Angels love tick-box simplicity. Show them you’ve done the homework on compliance and deadlines.
6. Risk Analysis & Mitigation
Every startup has risks. Address them head-on:
- Market shifts (plan B?)
- Tech obsolescence (upgrade path?)
- Regulatory hurdles (consulted a lawyer?)
Demonstrate you’ve thought through worst-case scenarios. That’s a big tick for startup angel investors.
7. Investor Involvement Style
Know your audience. Some angels want board seats and weekly calls. Others prefer a silent partnership. Set expectations early:
- Are you after strategic guidance or just funds?
- Will you offer a board observer role?
- How often will you report updates?
Alignment here avoids messy surprises down the line.
Comparing Platforms: Roundtable vs Oriel IPO
You might’ve stumbled across Roundtable’s article on what angel investors look for. They do a solid job. Roundtable strengths:
- Full legal and administrative support
- A broad network of investors and clubs
- An established brand in European private markets
But here’s where Oriel IPO steps up:
- Commission-free model—no fundraising fees chipping away your hard-won funding
- Curated SEIS/EIS opportunities—quality over quantity
- Subscription-based transparency—you know your costs from day one
- Educational tools: guides, webinars and even Maggie’s AutoBlog, our AI-powered content platform to help founders craft winning pitches
In short, Roundtable offers infrastructure; Oriel IPO pairs infrastructure with a laser focus on tax efficiency and cost transparency. That’s a key differentiator for bootstrapped founders.
Practical Tips to Shine for SEIS Angels
Ready for action? Here’s how to polish your pitch:
- Craft a crisp elevator pitch in one sentence.

Small tweaks can make a huge difference when startup angel investors compare you against ten other deals.

That’s solid. It turns data into a story: “We’ve proven product-market fit. Give us £200k to expand.” Clear, concise, compelling.
