For a scaleup or growth-stage technology company, it is not unusual to reach a point where additional capital is needed to support the next phase of growth. Founders must then decide whether raising capital makes sense again and, if so, what type of capital is best suited to the company’s needs.
Broadly speaking, there are two ways to raise it: sell ownership through an equity round or borrow through a venture debt facility. The immediate consequence of an equity raise is dilution, while debt must ultimately be repaid. There is no such thing as free money, and determining which trade-off is more appropriate depends far more on the company’s specific circumstances than most comparisons acknowledge.
For most SaaS, technology, and AI companies, equity remains the default. It is well suited to funding uncertainty and carries no repayment clock. Venture debt, on the other hand, is a narrower tool. Used in the right circumstances, it can extend runway, finance a specific growth initiative, or fund an acquisition while preserving ownership. Used in the wrong ones, however, it can become an obligation that comes due at the most challenging possible moment. This article examines when each option makes sense.
The question of equity versus venture debt has become more pressing since 2024. As venture markets remained selective and many rounds were repriced at lower valuations, the venture debt market continued to deepen. US venture debt reached a record $53B in 2024, even as deal count fell to a decade low, while AI companies raising capital to fund compute and expansion created a new source of demand. This piece compares the two on the dimension founders usually skip: not just cost and dilution today, but how each one shows up at exit.
What venture debt and equity are
Venture debt is debt financing provided to venture-backed, recurring-revenue, or high-growth companies that can support repayment but may not want to raise another priced equity round. It is usually structured as a loan or credit facility, often sized against ARR, revenue quality, cash runway, investor backing, or the most recent financing round. Like any debt, it must be repaid over a defined period, and it can carry interest, fees, covenants, warrants, or restrictions on how the capital is used.
Venture debt is often described as non-dilutive, which is its headline appeal. However, that description can also be slightly misleading. In practice, it is more accurate to describe venture debt as less dilutive. Many facilities include warrant coverage, typically around 0.5% to 2% for bank lenders and potentially higher for venture debt funds, meaning that a small equity component is often part of the deal. The dilution is substantially lower than in an equity round, but it is not always zero.
There is a second point that matters more than the label. As Juan Ignacio García, Managing Partner at L40°, explains: “A venture debt lender is not primarily underwriting whether the company can generate enough cash to repay the loan. The lender is underwriting how likely the company is to raise its next round, because that next round is often the main way the loan gets repaid. The bet is on trajectory: that the company continues raising capital, keeps growing, and eventually reaches a scale at which it can refinance or exit.” That is why a strong investor base and a credible growth story can matter as much to a lender as the company’s current P&L.
Equity financing is capital raised in exchange for ownership in the company. It requires no scheduled repayment, which makes it the more flexible instrument for funding product development, market expansion, hiring, and other long-term bets where the payback is uncertain. The trade-off is dilution. Founders and existing shareholders give up part of their ownership, control, and future upside, permanently.
The two are not simply opposites. Equity is better suited to financing uncertainty, while debt is better suited to financing visibility. Many growth-stage companies use both at different moments: equity to fund the broader company-building journey, and debt to extend runway, avoid unnecessary dilution, finance a specific initiative, or support acquisition-led growth. The useful question is not simply which is cheaper, but which type of capital best fits the company’s stage, risk profile, growth strategy, and potential exit path.
The real cost of capital
Founders often compare a debt coupon against equity's apparent zero coupon and conclude that equity is free. It is not. The honest comparison is the fully loaded cost of debt against the long-term economic cost of dilution, and over a successful company's life the second number is frequently the larger one.
Venture debt has more components than its interest rate. The all-in cost typically runs 8 to 15 percent (a SOFR or Prime base plus roughly 6 to 9 percent), with 1 to 2 percent upfront, 3 to 6 percent at end of term, plus warrant coverage and any covenants that constrain how the business operates. That is the explicit, knowable price.
Equity's cost is less visible and potentially much larger. Founder ownership erodes round over round, with dilution of 15 to 20 percent or more per round compounding to the point where the average founder holds only around 15 percent by IPO (if not less). The cost of equity is ownership given away at today's valuation for value that may be realized at a far higher one tomorrow.
A worked example makes the divergence concrete. Take a SaaS company with $10M ARR, 75 percent gross margins, growing 35 percent year over year, that wants $3M to extend runway and invest in go-to-market or to fund a small tuck-in acquisition. It has two options.
Now look at how the two diverge by the time the company exits three years later. If it sells at $40M, $75M, or $120M, the economic value of that 9.1 percent of equity is roughly $3.6M, $6.8M, or $10.9M. The debt, by contrast, costs roughly $1.0M to $1.2M in interest and fees, plus warrant value that scales with the outcome.
The point lands immediately. Debt costs more in explicit, near-term dollars. Equity costs more in the long run if the business performs well, because the slice handed over keeps growing with the company. That is the case for debt at its strongest. It is not a reason to default to it, only a reason to stop treating equity as costless.
When venture debt makes sense
Debt is the capital for execution. It works best when the company is financing something visible, with a repayment path that does not depend entirely on a future round arriving on schedule. The strongest cases share a few features:
- Strong, predictable recurring revenue. The cash base can carry scheduled repayment under a realistic plan, not only the optimistic one. This is the single most important test.
- A clear path to profitability. Repayment is not wholly dependent on the next financing event landing on time.
- A defined milestone to bridge to. The deliberate 12-to-18-month bridge: using debt to grow faster and reach a stronger position before raising, specifically to dilute less. This works when the founder is confident they can raise and is choosing to wait, not when they cannot raise at all.
- Expansion with measurable payback. Financing a growth initiative whose return is visible, for example an AI-native company funding compute against contracted revenue rather than diluting equity to cover a capacity cost.
- Acquisition-led growth. Debt tied to a specific tuck-in, customer-base expansion, or consolidation play, where the capital is matched to a transaction with its own revenue and integration logic.
When venture debt does not make sense
Equity is the capital for ambiguity. The honest cases against debt matter as much as the cases for it, because the failure mode is severe: an obligation that comes due whether or not the plan worked.
- Before product-market fit. Repayment obligations on an unproven model turn ordinary startup risk into existential risk.
- Unsustainable burn with no headroom. If the plan only works in the optimistic case, a repayment schedule removes the slack the company needs to absorb a miss.
- Covenant risk if growth slows. Covenants that are easy to clear at plan can become a constraint on a miss, shifting leverage to the lender at the worst moment.
- The “we’ll just refinance” assumption. This is the trap. If the next round is the repayment plan and the next round is in doubt, debt makes the problem worse, not better. García is blunt that taking venture debt as a last shot, after a round has failed to come together, is usually a flight forward rather than a solution.
Naming these cases is not a reason to avoid debt. It is how a founder figures out whether they are in the right situation for it. Most lenders apply the same filter, which is why structuring the raise properly, against the right metrics and with realistic covenants, is where the instrument either works cleanly or quietly creates risk.
How the choice shapes your exit
This is the part most venture debt versus equity comparisons leave out, even though it can ultimately determine how much value is left for founders, employees, and other common shareholders after an exit.
Start with the exit waterfall. Debt is senior, meaning that any outstanding principal, accrued interest, prepayment fees, and other amounts owed to the lender are generally repaid before equity holders receive any proceeds. This reduces the equity value available for distribution at close.
Equity affects the waterfall differently. The most obvious consequence is dilution: raising a new round permanently reduces the founder’s ownership percentage and, therefore, their share of the proceeds. However, ownership percentage alone does not tell the full story. Preferred investors may also hold liquidation preferences that entitle them to receive their invested capital back before common shareholders participate in the remaining proceeds.
The impact depends on the terms of the round. With a standard 1x non-participating preference, investors typically choose between receiving their original investment or converting into common shares and taking their ownership percentage. Participating preferred shares may allow investors to recover their preference first and then participate again in the remaining proceeds. Multiple liquidation preferences, seniority between financing rounds, cumulative dividends, and other investor protections can reduce the amount ultimately distributed to founders and employees even further.
Debt and equity therefore both appear in the exit waterfall, but in different places. Debt is repaid as a fixed senior obligation, while equity financing changes how the residual value is divided after those obligations have been settled. The same $100 million sale can leave a founder in very different positions depending not only on how much debt or equity the company raised, but also on the specific terms attached to each.
This illustration is deliberately simple. It assumes that the debt repayment is limited to $8 million and that the equity investors convert into common shares rather than exercising liquidation preferences. It also excludes interest, fees, warrants, taxes, transaction costs, escrows, earnouts, and management incentive arrangements.
Change the debt burden, the dilution level, the exit valuation, or the preference structure, and the result can quickly flip. That is precisely the point: the option that looks cheapest when the capital is raised is not necessarily the one that leaves founders with the most at closing. The only reliable way to compare the two is to model the full exit waterfall using the company’s actual terms.
How a buyer reads your cap table or balance sheet
Then there is the question of how a potential buyer reads the company’s capital structure. A financial sponsor will assess repayment headroom, covenant compliance, and how the debt behaves upon a change of control. Buyers will also consider what an over-diluted cap table may mean for founder alignment, particularly when the transaction includes an earnout or equity rollover.
Well-structured debt, with sufficient repayment headroom and straightforward change-of-control provisions, is typically a non-issue in diligence. By contrast, limited headroom, restrictive covenants, significant prepayment costs, or lender consent requirements can complicate negotiations, reduce flexibility, or make the transaction more difficult to close. A clean and sensible capital structure can therefore become a selling point in its own right.
Debt can also be interpreted as a sign of strength. For companies pursuing acquisition-led growth, including AI rollups and vertical software consolidation,, debt used to fund disciplined tuck-in acquisitions can demonstrate efficient capital allocation. When those acquisitions have added measurable revenue, expanded market position, and followed a clear integration strategy, the debt tells a story of execution rather than financial burden. The terms of the facility and the results produced with the capital determine which story the buyer hears.
The takeaway is that the best capital structure is not necessarily the one that appears cheapest in isolation. It is the one that preserves strategic flexibility at exit. Before entering a buyer conversation, founders should understand how outstanding debt, dilution, liquidation preferences, covenants, repayment obligations, and change-of-control provisions will affect both the transaction process and the final distribution of proceeds.
What this means for founders
The comparison translates into three practical steps founders should take before making a financing decision:
- Model the fully loaded cost of each option. For debt, that means accounting for interest, upfront and end-of-term fees, amortization, warrants, covenants, and repayment timing. For equity, it means modelling not only dilution at today’s valuation, but also how ownership, liquidation preferences, participation rights, and future financing rounds could affect the eventual distribution of proceeds. The right question is not simply whether debt carries a coupon and equity does not, but what each option costs if the company grows as planned, underperforms, raises again, or exits.
- Pressure-test the downside. Venture debt only works if the company can continue servicing it under a less optimistic plan. Founders should model scenarios in which revenue comes in 20% below expectations, a key customer delays an expansion, the next fundraising process takes longer than planned, or an acquisition integration runs over budget. If the company can continue operating and meeting its obligations under those conditions, debt may be a useful tool. If the downside case creates a liquidity crunch, equity is likely to be the safer source of capital, even if it is more dilutive.
- Decide with both the growth path and exit in view. The instrument should match what the capital is intended to achieve. Debt is generally better suited to execution: extending runway to a defined milestone, funding measurable go-to-market expansion, financing compute against visible revenue, or supporting acquisition-led growth. Equity is better suited to uncertainty, including new products, new markets, and investments whose payback has not yet been proven. Founders should also consider how each option will appear in a future buyer conversation, from repayment obligations, covenants, and change-of-control provisions to dilution, liquidation preferences, and founder alignment.
This is where having an advisor who works both sides of the decision matters. L40° advises technology and SaaS founders on strategic debt advisory as well as sell-side M&A. On the debt side, the firm helps founders judge whether debt is the right instrument at all, then structure the raise, prepare materials, approach the right capital providers, and negotiate terms that support the growth plan rather than constrain it.
On the M&A side, L40° helps founders prepare for and execute strategic exits through its sell-side advisory practice, making sure capital structure, buyer positioning, and transaction strategy are aligned before going to market. The financing choice and the exit are the same conversation, separated by time.
The bottom line
Deciding between venture debt or equity is not only about cost of capital today. It is important to understand how each option affects dilution, repayment obligations, operating flexibility, and how the company looks to a future buyer. Both debt and equity show up at exit, just in different places: debt in the repayment waterfall, equity in the ownership split. The founders who choose well are the ones who run the numbers on both before they commit to either.
