Why Growth Startups Borrow $2 to $3.5 Million to Stretch Runway Without Equity
Growth-stage startups use venture debt to extend their runway 6–12 months with far less dilution than an equity round.
Venture debt lets a founder borrow against expected growth without giving up the equity stake that comes with a funding round. A startup that raised $10 million in Series A can tap $2 to $3.5 million in venture debt, pay interest and fees over one to four years, and extend its runway by six to twelve months—the time needed to hit revenue targets, customer milestones, or profitability before raising again.
The structure appeals to founders who want to avoid the 15 to 30 percent ownership dilution of an equity round but need cash to bridge the gap between rounds. Lenders price the risk with higher interest rates, warrant coverage that gives them equity upside, and financial covenants that watch over the company's cash and growth. Understanding what those terms cost and require helps a founder decide whether venture debt or equity makes sense for their stage.
The cost structure: interest, fees and warrants
Venture debt interest rates typically range from 8 to 15 percent annually, priced as SOFR (currently around 4.5 percent) plus a 6 to 9 percent spread. For higher-risk startups, rates can climb above 20 percent. On top of interest, lenders charge upfront facility fees of 1.0 to 1.5 percent of the loan amount and end-of-term fees of 3 to 6 percent—costs that often surprise founders who focus only on the interest rate.
Warrants—the right to buy equity at a fixed price—are how lenders capture upside if the company succeeds. Standard warrant coverage sits at 1 to 2 percent of the loan principal, though aggressive lenders may push for 3 to 5 percent. A $3 million facility with 2 percent warrant coverage means the lender can buy $60,000 worth of equity at the price your last funding round set. The warrant survives loan repayment and typically gives the lender 7 to 10 years to exercise it.
A concrete example: a $2 million facility at 12 percent interest costs roughly $485,000 in interest payments over the life of the loan, plus a $60,000 end-of-term fee and $200,000 in warrant dilution at your last round's valuation. The true cost is not the interest rate; it is the full cash outflow plus the equity the warrants represent.
How lenders structure the repayment
Most venture debt facilities span one to four years and follow a predictable payment schedule. The first six to twelve months are typically interest-only, preserving cash while the company scales. After that period, you make monthly or quarterly payments that include both principal and interest for the remaining twelve to twenty-four months, until the loan is fully repaid.
The size of the facility depends on your most recent equity round. Venture debt typically represents 20 to 35 percent of the capital you raised in your last round—so a Series A founder who raised $10 million can expect to qualify for $2 to $3.5 million in venture debt. This relationship exists because lenders use your investors as a gauge of quality. They underwrite your VC backers' reputation and investment thesis, not your revenue or assets. A founder backed by a top-tier firm will find lenders more willing to participate than one backed by a less-known investor.
The covenants that lenders impose
Venture debt covenants are lighter than traditional bank debt but still carry teeth. Lenders typically require your company to maintain minimum cash balances and hit revenue or annual recurring revenue targets. You must also restrict additional debt and usually cannot pay dividends or approve major mergers without lender consent.
The tightest covenant for many founders is the minimum cash requirement. If the company burns cash faster than expected, it can breach the covenant and trigger a default, giving the lender the right to accelerate repayment. That acceleration can force founders to raise an emergency equity round or sell the company on unfavorable terms. The consequence makes venture debt risky for companies with unpredictable burn rates or experimental business models where customer acquisition or product-market fit remains uncertain.

Why founders choose venture debt over equity
The ownership math drives the decision. An equity round that raises $5 million typically costs 15 to 30 percent of the company. Venture debt that raises the same $5 million costs maybe 2 percent in warrants—a 7.5- to 15-fold smaller dilution. For founders with significant equity stakes and employees with stock options, that difference compounds across rounds and shapes eventual outcomes.
Venture debt also gives a founder more negotiating leverage in the next equity round. If you have twelve months of runway instead of six, you can afford to turn down investment at a poor valuation and wait for a better offer. You are less desperate, and investors know it. Over two-thirds of companies in the Bessemer Venture Partners portfolio have used venture debt, a sign the tool has become standard for growth-stage companies that want to stay lean between rounds.
The trade-off is mandatory repayment. Whether the company hits its milestones or struggles, the debt must be paid. Equity investors take the risk with you; venture debt lenders do not. That obligation means venture debt works best for companies with predictable growth and loyal customers generating recurring monthly revenue. It fails quickly for companies in experimental phases, entering new markets, or launching untested products where the outcome is genuinely uncertain.
When venture debt makes sense
A founder should consider venture debt when three conditions are met: the company has institutional backing (VCs recognized by venture debt lenders), unit economics are proven (customer acquisition costs and lifetime value are predictable), and cash needs are temporary (getting to breakeven or the next round, not surviving). If you are raising venture debt to keep a failing company alive while searching for a path to profitability, you are using it wrong.
Revenue-based financing offers an alternative for founders without VC backing. Those lenders price based on monthly recurring revenue, growth rate, and customer retention rather than your investors' pedigree. You give up a percentage of future revenue instead of equity, and the obligation ends once you have paid back a fixed multiple of the borrowed amount.
The decision between venture debt and a new equity round comes down to your runway needs and dilution tolerance. If you need six to twelve months and already have enough equity stake to matter, venture debt is likely cheaper. If you need twenty-four months or dilution costs you almost nothing because you still own 40 percent after two rounds, a modest equity raise may be simpler to manage and negotiate.
