One of my projects has grown past $2k/month, being software (low cost) and pretty much fully automated except for customer service and product updates which I develop myself. Where is the first point you start to invest your earnings back into the business?
Congrats on $2k/month! I don't think you're going to find a one size fits all approach especially since we don't know the business category you're servicing, whether it's B2B or consumer.
One potential avenue is to double down on however you've gotten to $2k/month now.
Why not run a few different experiments and then write up content breaking down what you've found has worked for you etc?
Thanks for the reply Winslow :)
The 2k has mostly been through organic growth through an app store essentially. So it's a bit tricky figuring out how to spend money there, but certainly something to think about.
I like the idea of putting it towards a few different experiments. Time is my limiting factor so could potentially be used to hire some freelance experts.
I personally would invest into quality content - that helps to drive more attention your project naturally. ROI might take time to manifest, but once you are on track it's naturally growing.
