Understanding Equity Finance: Angel Investment, Crowdfunding, and Mezzanine Finance
Discover how angel investors, crowdfunding platforms, and mezzanine finance can help fund your business growth—with added benefits like strategic guidance and tax relief.

When growing a business, especially in its early stages, finding the right type of funding is crucial. While traditional loans may suit some, others turn to equity finance—where investors provide capital in exchange for ownership in the business.
This article explores three key types of equity finance: angel investment, equity crowdfunding, and mezzanine finance, explaining how they work, their pros and cons, and where to learn more.
1. Angel Investment: More Than Just Money
Angel investors are typically high-net-worth individuals, often former entrepreneurs or professionals, who invest their own money in start-ups in return for equity. But their value goes far beyond funding.
Why Choose an Angel Investor?
Expertise and Mentorship: Angel investors usually bring extensive experience and can provide strategic advice.
Network Access: They can open doors to valuable contacts, suppliers, and even future customers or investors.
Flexible Terms: Unlike banks, angels often take a long-term view and may be more flexible on terms and valuation.
However, angel investors usually want to be involved in the decision-making process. Founders should be ready for input on key business matters—this partnership approach can be beneficial if the relationship is well-managed.
Tax Incentives
The UK government supports angel investing through the Seed Enterprise Investment Scheme (SEIS), offering generous tax relief to investors. Under SEIS, investors can claim up to 50% income tax relief on investments up to £100,000 per tax year.

Preparing for Angel Investment
Getting angel-ready means more than just a good pitch. You'll need solid financials, a clear business model, and an attractive equity offer.

2. Equity Crowdfunding: Democratise Your Capital Raise
Equity crowdfunding lets startups raise money by selling shares to a large number of investors—typically via online platforms like Crowdcube, Seedrs, or FundedByMe.
How It Works
You set a funding target and valuation, then launch a campaign on a crowdfunding platform. If the campaign succeeds, those who invested own equity in your business.
Pros
Access to a Wider Pool of Investors: Many investors may be drawn to your vision, not just your bottom line.
Marketing Boost: A successful campaign doubles as a brand awareness exercise.
Community Building: Your investors can become customers and brand ambassadors.
Cons
Time and Effort: Crowdfunding campaigns require extensive planning and marketing.
No Guarantees: Success isn’t assured—many campaigns fail to reach their targets.
Fees: Platforms often charge listing and success fees, ranging from 5% to 10%.
Just like with angel investing, SEIS and EIS tax incentives can make crowdfunding more attractive to potential backers.

3. Mezzanine Finance: Bridging Debt and Equity
Mezzanine finance is a hybrid instrument often used by businesses that are too large for angel investment but not quite ready for private equity.
How It Works
A funder provides a loan, typically unsecured, with a higher interest rate. If the business cannot repay the loan, the lender can convert the debt into equity—usually at a pre-agreed valuation.
Benefits
Retain More Control (Initially): You don’t give up equity upfront.
Flexible Structure: Payments can be structured around cash flow.
Ideal for Growth or Acquisition: Often used during buyouts or expansion phases.
Risks
Higher Costs: Interest rates are higher than traditional loans.
Dilution Risk: If repayments are missed, the lender could become a significant shareholder.
Mezzanine finance is usually best suited to companies with a proven track record and predictable revenues.

Final Thoughts
Equity finance can be a powerful enabler of growth—providing not just funds, but strategic guidance, credibility, and access to networks. But it comes with trade-offs: dilution of ownership, shared decision-making, and often, a more rigorous level of scrutiny.
The right choice depends on your business stage, growth ambitions, and how comfortable you are sharing control. Whether you’re pitching to angels, launching a crowdfunding campaign, or exploring mezzanine finance, preparation is key.
