Ringtones is what I first thought of when I read this:
Apparently JustFab works like this: once you buy something from their website, you become their “VIP member”. Then you will have to log into their website between the 1st-5th of each month and click “Skip This Month”. If no action is taken (either skip this month, or cancel your account), they just charge you a $39.95 fee every month.
A few comments down, someone actually makes the connection to the ringtone companies:
This business model reminds me of those fly-by-night mobile subscription services from the early 2000s. The ones who’d make you think you were buying a single ringtone, and the next thing you knew, you’d been surreptitiously signed up for a $29.99/month subscription.
I remember evaluating the books for one of those companies back in the day. It was wildly successful at the surface level. But if you dipped below the surface, you noticed that its biggest strategic weakness was “Breakage,” i.e., the rate at which people eventually discovered they’d been duped and then cancelled their subscriptions. It turned out that the average subscription lasted 2 to 3 months, and nobody kept a subscription longer than 5 months. This basically meant that the company’s entire business model was predicated on scamming new users at a rate quicker than its existing users could break away. While not a Ponzi scheme in the true sense, the model operates on a similar assumption. But the assumption is not sustainable in the long run.
