SaaS founder here. I can confirm that the first part of the article is true: you do get "stuck" eventually at a certain level, because your churn rate is a percentage of clients, while your new client acquisition rate is a constant (e.g. it does not depend on the number of your existing clients). So the two will eventually become equal to each other and your growth will slow and then stop, unless you start/increase your marketing and client acquisition efforts.
I don't like the word "stuck", though — I do not subscribe to the idea that endless growth is the Holy Grail, to be pursued at all cost.
I know, we are not supposed to discuss voting. But I'll still say that seeing an informative comment based on real-life experience of being a solo SaaS founder being downvoted is discouraging. It's a signal that I should stop contributing.
The article is about agencies and you are a SaaS founder. These are very different types of business with very different economics.
It’s fair for you to chip in with your experiences, but you shouldn’t start off by saying you are confirming the article is true, because you can’t. If you were speaking from your experience as an agency founder then you could confirm it, but your business is very different to an agency.
The problem a lot of people here have with this article is that it seems to be based on SaaS economics not agency economics. So for you to say you confirm it as a SaaS founder is propagating the problem people here see with the article.
