Not necessarily, but it should be able to be, and the sales efficiency ratio decides which. We measure it as sales and marketing cost in a period divided by the new ARR booked in that period, and lower is better. While it stays below 1.0, burning to grow is acceptable, provided sales and marketing accounts for all of the burn and a significant share of remaining operating expense. The test is what the business earns without new-account sales and marketing: at $5M it should be at least 25% profitable. If it is, the loss is a choice with a measured return, so keep investing. If sales efficiency runs above 1.0, or the business still falls short with that spend removed, the loss comes from churn replacement or a cost base that does not flex, and profitability becomes the priority.
Burn to grow only while the sales efficiency ratio is below 1.0, sales and marketing makes up all of the burn, and the business would be at least 25% profitable without new-account sales and marketing. If any of those fails, make profitability the priority.

At $5M, profitability is less a target than a diagnostic. A software company earns gross profit on its installed base every month, and the question is where that profit goes. If it goes into sales capacity that books new ARR at a known cost, the loss is an investment and it reverses when spending slows. If it goes into winning back customers who left, it never reverses. Our addendum puts a number on it: at 84% gross retention and a new-logo cost of $2.00 per dollar of ARR, replacing churn alone consumes about 32% of revenue.
That is why our portfolio work starts at 10% net profit. It is not austerity. Profit at this stage builds cash on the balance sheet, makes debt available on good terms, and gives the founder options when the market reprices, as software did in 2022 and again in 2026.
Read the P&L with new-account spend separated from the cost of standing still, compute the sales efficiency ratio for the same periods, then run unit economics by cohort. Whether you should be profitable is usually visible in that split.
Two companies at $5M ARR each run a −12% EBITDA margin. The first retains 108% net and 94% gross, books new ARR at $0.80 of sales and marketing per dollar, and spends about 37 points of revenue on new-account sales and marketing; take that out and it earns about 25%, so its whole loss is growth spend. The second retains 96% net and 84% gross and books new ARR at $1.40, so a large share of its sales budget replaces lost revenue; take out new-account spend and it earns under 10% while ARR shrinks within a year. The first company's loss is a choice. The second company's loss is its business model, and its priority is retention. Both companies are invented.
A loss is common here and often fine when it comes from measured growth spend. SaaS Capital's 2025 survey shows equity-backed companies at $1M to $3M ARR moving sharply toward breakeven, which is the direction buyers and lenders now expect.
The company should be at least 25% profitable with new-account sales and marketing removed, even if it chooses to keep spending. If it is not, the loss is structural.
Our benchmark trajectory is a 20%+ EBITDA margin at $10M and above, and at our target exit near $15M in annual revenue buyers expect predictable profit alongside growth.
A company in a planned, time-limited investment, such as a platform rebuild or a second product funded by equity for that purpose, can run a structural loss for a defined period. It should be dated, budgeted and reported to the board as exactly that.

When the sales efficiency ratio rises above 1.0, when sales and marketing no longer explains the whole loss, or before an exit process, whichever comes first. In our portfolio the sequence is 10% net profit first, then 20% as the company approaches a meaningful exit near $15M in annual revenue. The capacity to be at least 25% profitable without new-account spend is worth having even when you choose not to use it.
Not by itself. Check the sales efficiency ratio first: below 1.0, with sales and marketing making up all of the burn, the loss is buying growth. Then confirm the company would be at least 25% profitable without new-account sales and marketing, and that the burn multiple is under 1x; between 1x and 1.5x it deserves a look. If gross retention is below 90%, the loss is structural and it is the first problem to solve.
Our minority equity is built around this path, from net profit to 10% through operations and sales optimization to 20% and a meaningful exit. A company whose loss comes from churn is a fix-first conversation, and we would say so.
