Lending to software and AI companies before they make money: recurring revenue, unit economics, compute costs and runway.

Many software and AI companies borrow before they're profitable. EBITDA may be negative, so leverage multiples on EBITDA don't work. Lenders instead underwrite recurring revenue, the quality of that revenue, and how long the company can run before it needs more money.
These loans are often called recurring-revenue loans, sized as a multiple of annual recurring revenue (ARR) and protected by liquidity and revenue covenants rather than EBITDA tests.
| Metric | What it tells the lender |
|---|---|
| ARR and growth | The size and momentum of the recurring revenue base. |
| Net revenue retention | Whether existing customers spend more or less over time. Above 100% means the base grows on its own. |
| Gross margin including compute | How much of each revenue dollar survives the cost of serving it. |
| CAC, LTV/CAC and payback | Whether growth is efficient: what a customer costs to win, and how quickly it pays back. |
| Compute cost per unit | Cost per query, user or token. Watch the trend as usage grows. |
| Burn multiple | Cash burned for each dollar of net new ARR. |
| Runway | Months of cash at the current burn, before and after the loan. |
| Leverage on ARR | Loan size divided by ARR, the main sizing metric for recurring-revenue loans. |
Illustrative numbers only, not from any case. Suppose a software company has $50M of ARR growing 30% a year, net revenue retention of 110%, gross margin of 70% after compute, and burns $2M a month. It has $30M of cash and asks for a $25M term loan.
Tip
Always show runway with and without the loan, and compare it with the loan's maturity and the timing of the next expected equity raise.
Practice on the AI and tech case in the library. The model template for that case rolls ARR forward year by year, builds gross margin from usage and compute cost per unit, tests committed cloud spend for shortfalls, and runs cash after interest against the liquidity and debt-to-ARR covenants.
