How Venture Debt Works Alongside Equity for UK Scaleups
A plain-English guide to venture debt, how it complements equity funding rounds, and what founders should weigh up before taking it on.
What venture debt actually is
Venture debt is a loan facility designed for early-stage and growth-stage companies that do not yet have the assets, revenue predictability or profitability that traditional bank lenders usually require. Instead of lending against property, inventory or steady cash flow, venture debt lenders lend against a company’s growth trajectory, its investor base and the cash it has recently raised or is expected to raise.
It sits alongside equity rather than replacing it. Most venture debt providers will only lend to companies that have institutional venture capital backing, because the lender is relying partly on the credibility and continued support of those investors. In practice, venture debt is almost always taken out shortly after or alongside an equity round, not instead of one.
Why founders use it
The core appeal is that debt does not dilute ownership in the way equity does. If a founder takes on a venture loan instead of raising a slightly larger equity round, they keep more of the company for themselves and existing shareholders. This matters most for founders who believe their valuation will rise significantly before the next raise, since selling equity today at a lower valuation is more expensive in the long run than paying interest on a loan.
Venture debt is commonly used to:
- Extend cash runway between equity rounds, giving the company more time to hit milestones before raising again at a higher valuation.
- Fund specific, identifiable growth spending such as hiring a sales team, building inventory, or financing customer contracts, where the return on that spending is reasonably predictable.
- Provide a cushion or insurance policy that sits undrawn in case a fundraising environment turns difficult, without founders needing to raise more dilutive capital than necessary.
It is rarely used to fund a business with no realistic path to profitability or further fundraising, because the loan still has to be repaid regardless of how the business performs.
How the structure typically works
Venture debt is usually structured as a term loan, sometimes with a revolving credit element, sized as a proportion of the most recent equity round rather than against hard assets. Facilities are often drawn in tranches linked to milestones, rather than paid out in one lump sum.
Repayment usually involves an interest-only period followed by a period of capital repayment, so the monthly cost is lower in the early months. Interest rates are set with reference to prevailing benchmark rates such as the Bank of England base rate, plus a margin that reflects the risk of lending to an unprofitable, early-stage business. Because these benchmark rates and margins move with market conditions, founders should always check current pricing directly with a lender or adviser rather than relying on a figure from an old term sheet or article.
Most venture debt facilities also include warrants: the right for the lender to buy a small amount of equity in future, usually at the valuation of the most recent round. This gives the lender some upside if the company succeeds, compensating for the fact that the loan itself carries a fixed, capped return. Warrant coverage, like interest rates, varies by deal and lender and should be checked and negotiated case by case rather than assumed.
The risks founders need to understand
Unlike equity, debt has to be repaid on a schedule regardless of whether the business is performing well. If growth slows or the next funding round is delayed, loan repayments do not pause automatically, and missing them can trigger default clauses that give the lender significant control, including the ability to demand immediate repayment or take security over company assets.
Venture debt agreements typically include covenants: conditions the company must keep meeting, such as maintaining a minimum cash balance or hitting revenue targets. Breaching a covenant does not necessarily mean the loan is called in immediately, but it does give the lender leverage to renegotiate terms, often in the company’s least favourable moment.
Founders should also be aware that venture debt increases the company’s overall financial risk profile. It effectively brings forward some of the risk that would otherwise sit with equity investors and shifts it onto the company’s balance sheet as a fixed obligation. Combining a large debt facility with an already tight cash runway can leave a business with very little room to manoeuvre if plans slip.
Questions to ask before taking on venture debt
Founders considering venture debt should ask what the true all-in cost is once interest, fees and warrant dilution are combined, what covenants apply and how realistic they are given a cautious growth scenario, and what happens in a down-round or a failed fundraise. It is also worth asking existing equity investors whether they support the facility, since lenders often expect continued investor backing as an implicit condition of the loan.
Because terms, typical structures and market pricing shift over time, founders and advisers should check current guidance and lender directories rather than relying on historic figures, and should take independent legal and financial advice before signing any facility.
