Real-revenue cases
Two Bens who met in Bali run a London-based monthly non-fiction book club: one book, one meetup, one themed cocktail per month, funded by 570 members paying £15 a month for roughly £10.5K MRR.
01
It replaces the common habit of buying books and never finishing them — the founder calls himself a chronic case of tsundoku. What members pay for is the social commitment and deadline that gets the book finished, not the book itself, which is why they keep renewing.
Members pay a £15 monthly subscription covering one non-fiction book (delivered via Amazon vouchers), one in-person meetup, and one book-themed cocktail. Revenue is entirely subscription-based; the source claims a 95% gross margin.
Buying books and never reading them (tsundoku): one-tap Amazon purchases of non-fiction that stall before page 100.
02
Launched May 2015 with 24 paying members, recruited by posting the invitation on the founders' own social media channels.
03
Not an AI business itself, but the subscription playbook of using a fixed recurring meetup to create completion pressure transfers to AI learning or skill-training products: turning tool usage into a scheduled task with deadlines and peer pressure retains better than selling a bare tool subscription.

Revenue basis · Founder self-reported, unaudited (see source page)
The headline says $13K/month while the text says 570 members equal £10,500 MRR; the two figures don't reconcile, and both are unaudited founder claims.
The 95% gross margin and $18K starting cost come from Starter Story's summary panel with no stated methodology.
The text says churn is higher than they'd like because members can't always make meetups, but gives no actual churn rate.
