I wanted to know where my Gumroad money actually comes from. Not spiritually. Like… which links, which posts, which products.

So I asked Claude to draw me a Sankey diagram.

Now I can literally see my sales flowing from 9 different sources into each product. (Like a tiny plumbing system for my business.)

StackContacts does the boring part: → syncs the data → feeds it to Claude → lets me ask dumb questions like “Why is THIS random thing making money?”

The result: I finally know what’s working. And more importantly… what to stop pretending is working.

Data, but make it visual. Revenue, but make it honest.

Game: If 5 people comment “Sankey”, I’ll publish the exact prompt I used so you can build this with your own sales data.
