Selling prompt packs on Gumroad: $6,498 in 60 days
An anonymous self-reported case: a 100-prompt Midjourney pack for fantasy maps sold 342 copies at $19 in 60 days, then converted into an $8/month membership for 10 fresh prompts a week (214 members) — about 6 hours of total work. The catch: niches saturate fast, so the model only works with steady new packs.
