Ask HN: Side project has traction. I don't get get it

Hi all,

I ran a side project for the last few years. It's a hybrid me + SaaS. I spend time doing the initial data engineering to get the data in, and the SaaS is then used to manage the function.

Over the last year, thanks to word of mouth, I now have 3 clients and almost 7k in monthly revenue. The catch is, I'm reaching my personal capacity and any more and I will have to either spend more time on it, or start outsourcing various components and work.

Has anyone gone through a similar inflection point and could provide any tips or other advice?

Edit: One of the key things holding me back is it's in a way consulting + some tech. Not sure how that scales at all, if at all.
