Top 10 SEIS/EIS Investment Platforms and How to Build a Commission-Free Marketplace

Why SEIS/EIS and a Business Angel Platform Matter

Early-stage funding in the UK is tricky. Investors chase deals. Startups need cash. Enter SEIS/EIS. These government-backed schemes offer generous tax relief. A business angel platform makes the match. It connects founders with seasoned investors. Think of it as Tinder for funding—but with spreadsheets, legal docs and a bit less swiping.

Yet many platforms charge hefty commissions. That eats into your capital. Oriel IPO flips the script. A commission-free marketplace. Subscription-based. Curated, tax-efficient deals. Educational resources baked in. No cut of your raise. You keep more. Investors pay no hidden fees. Everyone wins.

In this guide, we’ll:

  • Compare the top 10 SEIS/EIS investment platforms.
  • Highlight their strengths and blind spots.
  • Show how to build your own commission-free business angel platform step by step.
  • Share real insights, not fluff.

Let’s dive in.

Top 10 SEIS/EIS Investment Platforms Compared

Here’s a quick rundown of the front-runners in the UK and Europe. We’ll call out what they do well and where Oriel IPO’s commission-free model fills gaps.

  1. Seedrs (https://www.seedrs.com)
    – Strength: Rigorous vetting—only ~1% of applicants get listed.
    – Weakness: 7.5% carry fee plus 0.75% on funds handled. Cuts deep into returns.

    – Weakness: Platform fees of 5% on successful raises. Plus payment processing charges.

  3. InvestingZone (https://www.investingzone.com)
    – Strength: Specialist in SEIS/EIS niches.
    – Weakness: Less transparent fee structure. Can surprise with admin costs.

  4. Crowd for Angels (https://crowdforangels.com)
    – Strength: No investor fees, minimum ticket ~£25.
    – Weakness: Not FCA-regulated. Limited advisory support.

  5. Crowd2Fund (https://crowd2fund.com)
    – Strength: Loan and equity options.
    – Weakness: Up to 10% arrangement fee on debt deals. Equity deals carry platform costs.

  6. SyndicateRoom (https://syndicateroom.com)
    – Strength: Co-investment model alongside angels.
    – Weakness: Access EIS fund requires £10k minimum. Fees can reach 2% per annum.

  7. Angels Den (https://angelsden.com)
    – Strength: Matchmaking with angel networks.
    – Weakness: Upfront listing fees, success fee up to 7%.

  8. SFC Capital (https://sfccapital.com)
    – Strength: Top SEIS fund by number of deals (2023/24).
    – Weakness: Fund-based model. Less control for individual investors.

  9. Mercia Asset Management (https://mercia.co.uk)
    – Strength: One of the UK’s largest combined SEIS/EIS funds.
    – Weakness: Fund management fees apply. Less transparent per-deal costs.

  10. Angel Investment Network (https://www.angelinvestmentnetwork.co.uk)
    – Strength: Massive global community. Free for investors.
    – Weakness: Just an introduction service. No transaction handling.

What you’ll notice: fees pop up everywhere. It’s either a carry fee, success fee or subscription. Very few are truly commission-free. And even those that look free often hide admin or processing costs.

Oriel IPO’s model? A flat subscription. No slicing of capital. Clear as day.

How to Build a Commission-Free Marketplace

Building a robust business angel platform isn’t rocket science. But it takes planning. Here’s your blueprint:

1. Research and Define Your Niche

Ask yourself:

  • Who are my users? (SMEs, angel investors, VCs)
  • Which sectors? Tech, life sciences, consumer?
  • Do I focus on SEIS, EIS or both?

Example: Oriel IPO started purely SEIS/EIS. It nailed compliance, then expanded.

2. Choose a Technology Stack

You have options:

  • White-label software (like LenderKit) for quick launch.
  • Custom build with React, Node.js, PostgreSQL.
  • Hybrid: off-the-shelf back end + custom front end.

We recommend a white-label solution if you want to go live fast and keep costs down.

3. Implement Subscription Billing

Ditch success fees. Use monthly or annual subscriptions:

  • Tier 1: Basic listing for startups (£99/month).
  • Tier 2: Enhanced deal promotion (£249/month).
  • Investor pass: Access to deals and analytics (£49/month).

Transparent. Predictable. No nasty surprises.

4. Integrate SEIS/EIS Tax Incentives

Make it idiot-proof:

  • Auto-calculate potential tax relief.
  • Generate SEIS 1 and EIS 3 certificates.
  • Show “net cost after relief” in real time.

That’s a game-changer for investors.

5. Vetting and Due Diligence

Quality matters. Steps include:

  • Review pitch deck, financials, team credentials.
  • Legal compliance check.
  • Investment readiness workshop.

Only list top 5-10% of applicants. Curated deals win trust.

6. Build Educational Resources

No one reads a dry PDF. Use:

  • Short how-to videos.
  • Interactive guides.
  • AI-generated blog posts via Maggie’s AutoBlog.
  • Webinars with guest experts.

Oriel IPO’s hub has grown user confidence and reduced support queries by 30%.

7. Design a Clean UX/UI

Keep it simple:

  • Clear calls to action.
  • Dashboards with deal status.
  • One-click e-signature for docs.
  • In-platform messaging.

Think Stripe meets LinkedIn.

8. Launch, Market and Iterate

  • Start with a closed beta. Gather feedback.
  • Partner with accounting firms and accelerators.
  • Offer free trials to build a user base.
  • Collect data, refine features.

Growth hack: embed social proof. “10 startups funded £2M in three months” looks good on your homepage.
