Why "37% MoM growth" can mislead you without your MRR base (I built a free tool around it)
The usual rule of thumb treats a given MoM growth rate as "good" no matter your size — but 37% MoM at $1k MRR and at $100k MRR are completely different animals. I checked it against Papermark's real public numbers, and a flat % threshold quietly misleads you depending on your base.
That bugged me enough that I built a free tool for the question I actually care about as a bootstrapper: will this business survive? You put in cash, MRR, growth and costs, and it gives you your runway, the month you hit zero cash, your break-even month, and whether you're "default alive" — and crucially whether each number is healthy for your stage, not just the raw figure.

It's viability-first on purpose — it only bothers with cap table / dilution if you're actually raising. And honest about what it is: a fast estimate, not a 40-tab FP&A model.
For those of you bootstrapping — genuinely curious: has a runway or growth number ever surprised you enough to change a decision (pricing, a hire, when to quit your job)? And what do you track it with today?
The part that resonated most wasn't the calculator—it was questioning the metric itself. A growth rate only becomes meaningful when you know the business underneath it. Two companies can both be growing 37% MoM while facing completely different strategic realities. Framing the conversation around survivability instead of isolated metrics feels like a much more useful way to help founders make decisions.
Exactly. That's basically why I stopped trusting my own dashboards, a number can look great and still be hiding the thing that actually matters underneath it.
Really appreciate you putting it that way. Thanks for the thoughtful read.
That's exactly what I was hoping someone would pick up on.
Reading your reply, I think there's one strategic business decision sitting underneath that distinction which becomes much more significant as the product evolves, but I don't think I can do the reasoning behind it justice in a thread.
Happy to explain what I mean if it's useful. What's the best email to reach you?
Appreciate that. Genuinely curious feel free to drop the gist right here. I think out loud in public on purpose, and other founders reading this will probably get something from it too.
The short version is this.
I don't think the biggest question is whether founders are looking at the right metrics.
I think it's whether the product should ultimately help founders interpret metrics—or help founders make the strategic decisions those metrics are pointing toward.
Those sound similar, but I don't think they become the same business.
One helps people understand numbers.
The other helps people decide what to do next.
That's the distinction that stuck with me reading your post.
I have a much longer line of reasoning behind it, but I don't think I can do it justice in a thread without turning it into an essay.
That's a sharp way to frame it and I think you've named the bet Startkeel wants to make: it's built to help founders decide what to do next, not just interpret the numbers. The score, the verdict, the "one thing to fix", all of it serves the decision, not the dashboard.
Which is exactly why I'd rather keep this kind of thinking out in the open — other founders reading get the value too. Appreciate you pushing on it.
