One user spent nearly $600 in a year: a dev shows AI subscription upgrade paths

Developer gefei55 shared the full payment trail of a single AI product user: registered Jan 7 with a $300 annual plan, bought two $39.9 credit packs on Apr 25 after exhausting credits, then upgraded to a $149.99/month subscription on Oct 8 with auto-renewal still active — roughly $600 spent in one year.
The takeaway: heavy users with real willingness to pay exist, and accumulating a few hundred of them makes a viable business — a case study in how credit packs plus plan upgrades drive ARPU growth for subscription AI products.
