Regus has been selling that for ages and ages. They have more locations in more cities in more countries, too. If they're not as well-known, I'm guessing it's because they're just a boring old real estate company and not a SoftBank-fueled moon rocket.
I've always wondered why WeWork didn't operate more on a "franchise" model. Lots of property management companies have empty space that will be empty for a year or two, and the WeWork system is useful to install against, along with its brand, so these management companies should be able to "install" a WeWork for a year or whatever while their space is vacant, to help offset the lost revenue from leases.
Shifting the revenue to a franchise model seems like it solves the majority of their lease issues, and still lets them be useful, even in smaller markets. Their value, IMO, is in the "seamless" experience. Knowing I can paratroop into a city and will have a space to work that's of a consistent quality is great, someone sell me that!
