Real-revenue cases
A Denver bartender tracked down the Chinese factory behind the hit Lyfe levitating planter on Alibaba, bought the same hardware, and resells it on Amazon at roughly $4K a month (self-reported).
01
It swaps a plain desk planter for a floating one; demand was pre-validated by the Lyfe planter's strong reviews, holding at ~30 units a month with holiday spikes. Still a discretionary novelty buy rather than a must-have, so 'want' fits better than 'real'.

Ordinary static planters and desk decor, replaced by a floating novelty display.

His first sales came after Makezine found his project on Hackster.io and featured it; he then sold ~150 units over his first holiday season from a bare-bones Amazon listing shot on an iPhone.

Not an AI business, but the loop transfers: post working demos of your AI tool in dev communities to earn free press and influencer reach — a proven AI cold-start path. And the 80%-one-platform dependency mirrors AI apps built entirely on one model API; own your customer list early.

Revenue basis · Founder self-reported, unaudited (see source page)
The $4K/month revenue and 50% margin are founder self-reported and unaudited.
The business shut down in 2023 with the reason listed only as 'Shut down', so the playbook's long-term durability is unproven.
No data on net profit after ad spend, return rates, or repeat purchases; the own site gets ~10 uniques/day, so off-Amazon performance can't be judged.
