Short answer
Equity costs ownership and doesn't need repaying; venture debt costs interest, fees and often a small warrant, and does need repaying. Debt suits companies with a clear path to breakeven or their next round, because they can service it. Equity suits riskier spending with no near-term route to repayment. Many venture-backed companies use both: equity first, then debt alongside to extend runway with less dilution.
Key facts
| Venture debt | Equity | |
|---|---|---|
| Dilution | None, or small if warrants | Significant |
| Repayment | Yes, with interest | No |
| Cost if you succeed | Lower | Higher |
| Cost if you struggle | Higher (must still repay) | Lower |
| Control | Covenants; rarely a board seat | Often board seats and investor rights |
| Speed | Weeks | Months |
Illustrative example: raising £2m both ways
Illustrative example. A company with a £25m post-money valuation needs £2m.
- As equity: selling £2m of shares at that valuation gives up 8% of the company.
- As venture debt: if the loan includes 10% warrant coverage, the lender gets warrants worth £200,000 at the round price, about 0.8% of the company, plus interest and fees over the loan's life.
If the company is later sold for £75m, the 8% equity stake is worth £6m. The debt's total cost, including the warrants, is around £1m. If the company fails to grow, the debt must still be repaid.

When equity is the better choice
- You are pre-revenue or early in finding product-market fit
- The spending has no near-term route to repayment
- You have little runway left
- You want investors' networks and support as well as cash
When venture debt is the better choice
- You have recently raised equity and have supportive investors
- Revenue is recurring and growing
- You can see a path to breakeven or a bigger next round
- You want to reach a milestone before raising at a higher valuation
Using both together
The most common pattern is equity first, then venture debt alongside or shortly after, sized to add 6–12 months of runway. The equity gives the lender confidence; the debt lets the company reach its next valuation step with less dilution.
