As a solo founder with freelance gigs, I try to simplify everything.
Therefore, since I launched kingdom.so (ProductHunt meets Catan), I used only one Notion table to manage my growth and marketing strategy.
Here the link (you can clone it):

It's pretty straightforward; I just list all the experiments that I want to do, for example, "make a post on IH." I report the effort (time) and cost (money) that I used, and then I write the result.
I kept my past experiments as an example in the template.
I am curious about how you handle it?
Thanks for sharing your notion page !
