Raising money for a young company is rarely straightforward. Founders juggle competing priorities, tight timelines and an alphabet soup of financial instruments. Three concepts sit at the heart of early-stage fundraising in the UK: venture capital itself, convertible loan notes and bridging rounds. Each serves a distinct purpose, yet they frequently overlap in practice. This guide explains how they work, when they make sense and what founders and investors should watch out for.
What Is Venture Capital?
Venture capital (VC) is a category of private equity in which professional fund managers invest pooled capital into businesses that are too young or too risky for conventional bank lending. The investor receives shares in the company rather than interest payments, betting that the company will grow in value and eventually deliver a return through a sale, merger or public listing.
VC investors accept a high failure rate across their portfolio because the winners can generate returns many times the original investment. That risk-reward profile shapes everything about how VC deals are structured, from the legal documents to the board seats that investors negotiate.
How VC Differs from Traditional Lending
A bank lender evaluates whether the borrower can service debt from existing cash flow. A venture capitalist evaluates whether the business model can scale to a point where the equity becomes far more valuable than the amount invested. The lender wants predictability. The VC wants exponential growth.
This distinction matters because it explains why instruments like convertible loan notes exist. They sit between the two worlds, giving investors some of the protections of debt while preserving the upside of equity.
The Stages of Venture Capital Funding
Most VC-backed companies move through a series of funding rounds, each larger than the last. The naming conventions are broadly standardised, though the boundaries between stages can blur.
Pre-Seed
Pre-seed is the earliest external funding a company receives. At this stage, the product may be little more than a prototype or a detailed plan. Funding typically comes from the founders themselves, friends, family and early-stage angel investors. Rounds are usually small, often between £25,000 and £250,000, and are frequently structured as convertible instruments rather than priced equity because agreeing a valuation is difficult when revenue is minimal or non-existent.
Seed
Seed funding is the first significant round from external investors. Angel networks, seed-focused VC funds and accelerator programmes are the main participants. The company will typically have a working product and some evidence of market demand. Seed rounds in the UK commonly range from £250,000 to £2 million, though this varies by sector.
Series A
Series A is where institutional venture capital firms tend to enter. The company needs demonstrable traction: recurring revenue, a growing user base or clear evidence that the business model works at small scale. Series A rounds in the UK often fall between £2 million and £10 million. The valuation negotiation at this stage is detailed and data-driven, with investors scrutinising unit economics and market size.
Series B and Beyond
Series B, C and later rounds fund continued expansion. The company may be entering new markets, acquiring competitors or investing heavily in product development. Round sizes increase significantly. By Series C, the company is typically generating substantial revenue and the discussion shifts from whether the model works to how fast it can scale.
Exit
The ultimate goal for VC investors is an exit, the event that turns paper returns into real cash. Exits take several forms: trade sale to a larger company, initial public offering (IPO) or secondary sale of shares to another investor. The exit strategy influences every decision made during the funding journey, including which instruments are used along the way.
What Are Convertible Loan Notes?
A convertible loan note (CLN) is a financial instrument that starts life as a loan and converts into equity at a later date. The investor lends money to the company under a loan agreement. Rather than being repaid in cash, the loan converts into shares when a specified trigger event occurs, almost always the company’s next equity funding round.
CLNs have become one of the most popular instruments for early-stage fundraising in the UK. They allow founders and investors to move quickly without getting stuck on the question that slows down every equity round: what is the company actually worth?
The Core Mechanics
The CLN agreement specifies several key terms that determine how and when conversion happens.
Principal and Interest The investor provides a lump sum (the principal) which accrues interest at a fixed annual rate, usually between 5% and 10%. The interest is not paid in cash during the life of the note. Instead, it rolls up and converts into shares alongside the principal when the trigger event occurs.
Trigger Event The trigger is the event that causes the loan to convert into equity. The most common trigger is a qualifying funding round, meaning an equity round that meets a minimum size threshold. If the company raises a Series A of at least £1 million, for example, the CLN converts automatically.
Discount Rate The CLN holder receives shares at a discount to the price paid by new investors in the trigger round. A 20% discount is standard in the UK market. If new Series A investors pay £1.00 per share, the CLN holder pays £0.80 per share, receiving more shares for their money as a reward for investing earlier and taking on more risk.
Valuation Cap The cap sets a ceiling on the valuation at which the CLN converts. If the company raises its Series A at a £12 million valuation but the CLN has a £6 million cap, the CLN holder converts at the £6 million valuation regardless, effectively receiving twice as many shares as they would without the cap.
The CLN holder benefits from whichever mechanism (discount or cap) produces the lower price per share.
Maturity Date If the trigger event has not occurred by the maturity date (typically 12 to 24 months from the date the note is issued), the agreement must address what happens next. Options include automatic conversion at a pre-agreed valuation, extension by mutual agreement or repayment of the loan in cash. In practice, repayment is rare because most early-stage companies lack the cash to repay.
A Worked Example
Suppose an angel investor lends £50,000 to a software company via a CLN. The terms are:
- Interest rate: 8% per annum
- Discount: 20%
- Valuation cap: £4 million
- Maturity: 18 months
Fourteen months later, the company closes a Series A round at a pre-money valuation of £8 million. New investors pay £2.00 per share.
The accrued interest over 14 months is approximately £4,667, bringing the total amount to convert to £54,667.
Under the discount, the CLN holder would pay £1.60 per share (£2.00 less 20%), receiving roughly 34,167 shares.
Under the cap, the effective price per share is £1.00 (because the cap is half the actual valuation), giving the CLN holder roughly 54,667 shares.
The cap produces the better outcome, so the investor receives approximately 54,667 shares. A new investor putting in £54,667 at the Series A price would receive only 27,334 shares. The CLN holder ends up with double the shares, reflecting the earlier risk they took.
Bridging Rounds in Venture Capital
A bridging round is a smaller fundraise that sits between two larger funding rounds. It provides the company with enough capital to continue operating and hit the milestones needed to make the next major round viable.
Why Bridging Rounds Happen
Several scenarios lead to bridging rounds.
Milestone Gap The company has made progress since its last round but has not yet hit the metrics that Series A (or Series B) investors require. A bridge provides six to twelve months of additional runway to close the gap.
Market Timing External factors, such as an economic downturn or sector-wide pullback in investor appetite, may make it a poor time to raise a full round. A bridge allows the company to wait for better conditions without running out of cash.
Extended Due Diligence A lead investor for the next round may be interested but needs more time to complete due diligence. A bridge keeps the lights on while that process plays out.
Strategic Pivot The company has identified a new direction that requires a short period of investment before it can demonstrate traction to new investors.
How Bridging Rounds Are Structured
Most bridging rounds use convertible loan notes. The logic is straightforward: both the company and the bridge investors want to avoid setting a valuation during a period of uncertainty. A CLN defers that question to the next priced round.
Bridge CLNs often carry more investor-friendly terms than standard seed CLNs. Discounts of 25% to 30% and lower valuation caps are common because bridge investors are typically stepping in at a moment of higher risk.
Existing investors usually lead bridging rounds because they already hold equity and are motivated to protect their investment. New investors are less likely to participate because a bridge often signals that the company is struggling to raise a full round.
Bridging Round Risks
Founders should be clear-eyed about the risks.
A bridge that does not lead to a successful next round can leave the company in a worse position. The debt overhang from unconverted CLNs complicates future fundraising. Multiple bridge rounds in succession are a red flag for prospective investors and can result in severe dilution for founders.
Investors considering a bridge should ask pointed questions. What specific milestones will this capital fund? What is the realistic timeline for the next round? What happens to the notes if the next round does not close?
Convertible Loan Notes vs Equity Rounds
Choosing between a CLN and a priced equity round depends on the company’s stage, the amount being raised and the relationship between founders and investors.
When CLNs Make Sense
CLNs work best in the following situations:
- The company is too early to support a credible valuation.
- The round is small (under £500,000) and speed matters more than precision.
- The company expects to raise a larger priced round within 12 to 18 months.
- Legal costs need to be kept low. A CLN can often be documented for £2,000 to £5,000 compared with £15,000 to £30,000 for a full equity round.
When Equity Is Preferable
Equity rounds are better suited when:
- The company has clear traction and can justify a specific valuation.
- The round is large enough to justify the legal costs.
- The founders want certainty about dilution and cap table clarity.
- Institutional investors are leading the round and insist on standard preferred share terms.
The Dilution Question
One common misconception is that CLNs avoid dilution. They do not. They defer it. When the CLN converts, the founders’ ownership is diluted just as it would be in an equity round. In fact, the discount and cap mechanics mean that CLN holders often receive more shares than they would have if they had simply participated in the priced round, resulting in slightly greater dilution than a straight equity raise at the same valuation.
Founders should model the cap table impact of outstanding CLNs before entering valuation negotiations for a priced round. Surprises at the cap table stage can derail a deal.
Advantages and Risks of Convertible Loan Notes
Advantages for Founders
Speed of execution. A CLN round can close in days rather than weeks. The documentation is simpler and the negotiation points are fewer.
Valuation flexibility. Early-stage valuations are inherently uncertain. Deferring the question to a later round, when more data is available, can produce a fairer outcome for everyone.
Lower transaction costs. Shorter documents mean lower legal bills. For a small raise, this can be significant relative to the amount of capital raised.
Rolling closes. Unlike a priced round, which typically requires all investors to sign and fund simultaneously, CLNs allow a rolling close. The company can accept investment from different investors over a period of weeks or months.
Advantages for Investors
Downside protection. As a debt instrument, a CLN gives the investor a legal claim against the company if things go wrong. In an insolvency, debt holders rank ahead of equity holders in the creditor hierarchy, though in practice the assets of a failed startup rarely cover any claims. Understanding how debentures and security interests work provides useful context for investors evaluating their position in a worst-case scenario.
Upside participation. The discount and cap ensure that the CLN holder receives equity on more favourable terms than later investors, compensating them for the additional risk.
Simplicity. Fewer negotiation points mean faster deployment of capital.
Risks for Founders
Debt on the balance sheet. Until conversion, a CLN is a liability. This can affect the company’s financial position and may cause issues if the company needs to demonstrate solvency.
Maturity risk. If the trigger event does not occur before the maturity date, the company may face a demand for repayment it cannot meet.
Stacking problem. Multiple CLN rounds with different terms create a complex web of conversion rights that can confuse new investors and complicate cap table management.
Risks for Investors
Limited control. CLN holders typically do not receive board seats, voting rights or information rights until conversion.
Conversion uncertainty. If the trigger event never occurs, the investor may end up holding worthless debt rather than equity in a growing company.
Subordination. If the company takes on secured debt (such as a commercial property loan or asset finance), that secured debt may rank ahead of the unsecured CLN in an insolvency. Investors should understand the distinction between secured and unsecured positions, including the role of share charges in protecting creditor interests.
SEIS and EIS Considerations
The UK government’s Seed Enterprise Investment Scheme (SEIS) and Enterprise Investment Scheme (EIS) offer generous tax reliefs to investors who subscribe for shares in qualifying companies. These schemes are a major incentive for angel investors and can make the difference between a round succeeding or failing.
However, SEIS and EIS relief is only available on equity investments, not on loans. A CLN does not qualify for SEIS or EIS relief until and unless it converts into eligible shares. This creates a timing risk: the investor does not receive the tax relief at the point of investment but only at conversion, and only if the company still qualifies at that point.
Some companies address this by offering investors the choice between a CLN and a small equity subscription that qualifies for SEIS or EIS. Others issue advance subscription agreements (ASAs) instead of CLNs because some advisers consider ASAs more compatible with SEIS and EIS, though HMRC’s position on this remains a matter of ongoing professional debate.
Founders raising from UK angel investors should take specialist tax advice on structuring their round to preserve SEIS and EIS eligibility. The tax relief can be worth up to 50% of the investment amount under SEIS and 30% under EIS, so getting this wrong has a material impact on investor appetite.
How Bridging Rounds Relate to Property Bridging Finance
The term “bridging” appears in both venture capital and property finance, and the underlying concept is the same: short-term funding that bridges a gap between two events.
In venture capital, a bridging round bridges the gap between two equity funding rounds. In property, a bridging loan bridges the gap between acquiring a property and arranging longer-term finance or selling the asset. Both are temporary by design, with a clear exit strategy baked into the structure from the outset.
The parallels run deeper than the name. Both forms of bridging finance tend to be more expensive than their long-term equivalents because the lender or investor is taking on timing risk and uncertainty. Both require careful planning around the exit. And both can go wrong if the expected exit does not materialise on schedule.
Property bridging loans are typically secured against the asset being purchased, which gives the lender a tangible fallback. The loan-to-value ratio determines how much the lender will advance relative to the property’s worth. VC bridging rounds, by contrast, are usually unsecured, leaving the investor exposed if the company fails before the next round closes.
Speed is another shared characteristic. Just as a VC bridging round can be structured and closed in a matter of days using a CLN, a property bridging loan can be arranged far faster than a traditional mortgage. Depending on the lender and the complexity of the deal, it is possible to complete in a very short timeframe.
The growing role of alternative lenders across both property and business finance reflects a broader shift away from rigid institutional processes and towards flexible, deal-specific structures. Whether you are a founder raising a bridge between seed and Series A or a developer funding a construction project while waiting for planning permission, the principle is the same: find the right capital for the right moment.
Practical Tips for Founders
Before Raising on a CLN
Model the dilution. Build a cap table model showing how the CLN converts under different scenarios. Understand what your ownership looks like if the next round values the company at the cap, at double the cap and at half the cap.
Keep terms standard. The more bespoke the CLN terms, the harder it becomes to raise the next round. Stick to well-understood structures and use templates from organisations like the British Private Equity and Venture Capital Association (BVCA).
Set a realistic maturity date. Give yourself enough time to hit the milestones and close the next round. Eighteen months is a common and sensible timeframe.
Limit the number of CLN rounds. One CLN round before a priced round is normal. Two is workable. Three or more starts to create serious complexity and signals to prospective investors that something is wrong.
Communicate with CLN holders. Even though CLN holders do not have the same information rights as equity investors, keeping them updated builds trust and makes future fundraising easier.
During a Bridging Round
Be transparent about why. Investors who participate in a bridge need to understand why a full round is not being raised. Honesty about the challenges the company faces builds more credibility than spin.
Define clear milestones. Specify exactly what the bridge capital will fund and what metrics the company needs to hit to raise the next round.
Negotiate fairly. Bridge investors are taking significant risk. Overly aggressive terms from the company side can poison the relationship with existing backers.
Have a Plan B. If the next round does not close, what happens? Founders should have a realistic alternative plan, whether that is revenue growth to self-sustainability, a smaller follow-on bridge or a managed wind-down.
Understanding the Regulatory Landscape
Venture capital fundraising in the UK operates within a regulatory framework overseen by the Financial Conduct Authority (FCA). Companies raising capital need to be aware of the financial promotion rules, which restrict how investment opportunities can be marketed to the public.
CLNs are generally classified as securities. Promoting them to retail investors without appropriate exemptions is a regulatory offence. Most early-stage fundraises rely on exemptions for high-net-worth individuals or self-certified sophisticated investors.
Property bridging finance has its own regulatory considerations. Loans secured against an individual’s primary residence are typically regulated by the FCA, while loans for investment or commercial purposes are often unregulated. The distinction matters because it affects the protections available to the borrower and the speed at which the lender can process the application.
Founders who are raising VC while also engaging with property finance should ensure they have appropriate legal advice covering both regulatory regimes. The consequences of getting financial promotions wrong can be severe, including personal liability for directors.
The Current Funding Environment
The UK venture capital market has matured significantly over the past decade. According to industry data, UK-based startups consistently attract more VC investment than any other European country, though the market remains cyclical. Interest rate movements affect both property and venture markets, influencing investor appetite and the terms available to founders.
In tighter funding environments, CLNs and bridging rounds become more common because full priced rounds take longer to assemble. Founders who understand these instruments and can deploy them effectively have a meaningful advantage over those who wait for the perfect equity round that may never arrive.
The best founders treat fundraising as a continuous process rather than a discrete event. They build relationships with investors long before they need capital, maintain a clean cap table and keep their options open across different instrument types.
Frequently Asked Questions
What is the difference between a convertible loan note and an advance subscription agreement?
A convertible loan note is a debt instrument that converts into equity. An advance subscription agreement (ASA) is structured as a forward contract for shares rather than a loan. The practical effect is similar, but the legal classification differs. ASAs do not create a debtor-creditor relationship, which some advisers believe makes them more compatible with SEIS and EIS tax relief. However, HMRC has not issued definitive guidance, so professional advice is essential.
Can a convertible loan note holder demand repayment?
It depends on the terms of the note. Most CLNs include a maturity date after which the holder has the right to request repayment if the trigger event has not occurred. In practice, demanding repayment from an early-stage company that lacks the cash to repay is rarely productive, so maturity negotiations usually result in an extension or a conversion at an agreed valuation.
How much dilution should founders expect from a bridging round?
The dilution depends on the amount raised, the discount and the valuation cap relative to the eventual priced round. As a rough guide, a bridge of 10% to 15% of the next round’s target size, with a 20% discount and a reasonable cap, might result in 3% to 8% additional dilution beyond what the priced round itself causes. Founders should model specific scenarios rather than relying on rules of thumb.
Are convertible loan notes suitable for property development companies?
Property development companies typically raise finance through secured lending rather than CLNs. A bridging loan or development finance facility secured against the property is the standard approach. CLNs are more commonly used by technology and high-growth companies where the value lies in intellectual property and future revenue rather than physical assets. However, a property company raising equity from investors (rather than debt from lenders) could use a CLN if the circumstances warranted it.
What happens to convertible loan notes if the company is acquired before the next funding round?
Most CLN agreements include provisions for a change of control. The note may convert into equity immediately before the acquisition closes, allowing the CLN holder to participate in the sale proceeds. Alternatively, the note may become repayable at a multiple of the principal (commonly 1.5x to 2x) as compensation for the lost equity upside. The specific terms depend on what was negotiated in the CLN agreement, so founders and investors should pay close attention to the change-of-control provisions when the note is drafted.
