The metrics that don't apply to you. And why VCs push them anyway.

Most SaaS metric advice is written by, or for, venture-backed companies. That's not a conspiracy — it's just where the money and the blog posts are. But it means a lot of "best practice" is calibrated for a business that's deliberately burning investor capital to grow as fast as possible, and then quietly applied to companies that are nothing of the sort. If you're running a profitable, mostly bootstrapped SMB SaaS, several of the most-quoted numbers in the genre will either not apply to you at all, or actively mislead you. Here are the main offenders.

Burn Multiple: you may not have one, and that's the point

The Burn Multiple — net cash burn divided by net new ARR — is the metric of the efficiency era, and it's a good one for the companies it's built for. But it's a pure venture number. By definition it only means anything if you're spending more than you make. A profitable company has negative burn, so the multiple doesn't compute. That's not a gap in your reporting. It's the goal.

I never had a burn multiple at my company, because we were profitable, and I'd encourage any bootstrapped founder to feel exactly zero anxiety about that. Don't contort a healthy P&L to manufacture a number investors talk about. The instinct underneath the metric — how efficiently am I turning spend into growth — is universal and worth having. But the metric itself is for people deploying a war chest.

Magic Number: the same signal, in a costume you can't act on

The Magic Number — net new ARR over the prior quarter's sales and marketing spend — is sold as the read on whether your go-to-market engine is paying off. It's fine. But here's what I found running it: it's the same signal your CAC Payback already gives you, in a form that's harder to act on. A 0.9 Magic Number is a sentence you take to the board. "I spent $2,500 to land this customer and it takes X months to earn it back" is a sentence you take to a budget meeting and actually do something with.

It's also, at heart, a capital-deployment metric — its whole job is to tell you how hard to push spend when you've got outside money and a clock. For a bootstrapped company growing profitably and steadily, it matters far less than payback and the P&L. We computed it; it lived on the board deck; it never drove a decision.

DAU/MAU: a consumer benchmark wearing a B2B suit

Stickiness — DAU/MAU — comes with a famous benchmark: 20% is "good." That number comes from consumer apps fighting for attention against everything else on your phone. Importing it into B2B is a category error in both directions. A daily-use B2B tool that reps live in should run far higher than 20%, so the benchmark sets your bar embarrassingly low. And a B2B tool that's weekly or monthly by design might sit well below 20% and be perfectly healthy — the low number is the design working as intended.

Worse is the aggregate version. If stickiness across 3,000 accounts ticks up or down 2% in a week, what do you actually do? Nothing — there's no lever you pull on an average. The real signal lives at the account level, where a specific customer's falling login pattern is a churn warning you can still act on. Read it there, against your own product's natural rhythm, or don't read it at all.

Quick Ratio's "4": a number that punishes SMB for being SMB

The SaaS Quick Ratio — new plus expansion MRR over churn plus contraction — comes with a benchmark of 4 that gets quoted like gravity. But that figure was calibrated for low-churn, expansion-heavy SaaS. SMB carries structurally higher churn, and expansion is harder because the accounts are smaller with fewer seats to grow into. So both halves of the ratio fight an SMB business, and a perfectly healthy $1–10M company can sit at 2.5 and feel like it's failing some universal test. It isn't. It's living in the reality of its market. Judge yourself against your market, not a benchmark built for a different one.

So what should you watch instead?

The through-line in all four is the same: the venture playbook optimizes for deploying capital to maximize growth, and a bootstrapped business optimizes for durable, profitable growth on its own steam. Different game, different scoreboard. The numbers that actually told me how my business was doing were the unglamorous ones.

Watch your CAC Payback — it's the sales-efficiency question in a form you can act on. Watch your revenue churn and net revenue retention, because the leaky bucket is the thing that quietly kills durable companies. Watch Rule of 40 for the balance of growth and profit — but read how you got to the number, not just the sum. And watch your runway as a survival clock, because cash discipline is universal even when the venture metrics aren't.

None of this means the venture metrics are wrong. They're right, for the company they're built for. The mistake is assuming that company is you. If you're profitable and bootstrapped, you've already opted out of the game those numbers score — so stop letting them tell you you're losing it.
