Nice. If you don't mind me asking, how do you get customers? Do they find you via the Slack store? Or do you go out selling this? Or do you get people find you via search? Or ads?
I am always tempted to make a slack app. Not this particular idea, likely something else.
I don't mind. It's mostly via Slack app directory, sometimes I get through my links. I specifically wanted to build an idea in a marketplace to solve the discovery problem (as I suck at outbound marketing or any marketing in general).
If you're looking to build in any marketplace, shopify is more strealimed as majority of the shopify's users spends on the apps (and the billing and stuff is integrated) compared to any other marketplace.
