Every one of the startups in this space either disappears, or pivots their focus to larger spaces designed for meetings, events or shoots. For example there's https://breather.com in the US and https://www.vrumi.com in the UK. The cheapest space on vrumi is far more expensive than WeWork.
Another consideration is that private homes-as-workspaces can offer some incidental cost savings in the form of things you get with residential zoning like (usually) free parking and a car-based commute that does not follow urban congestion patterns. Say you need to work within 40 minutes of Paris or downtown LA in order to make the odd off-hours mixer or client meeting, but your daily workflow can be conducted entirely within a single dedicated space out in the burbs, priced comparably to the shared desks at a WW location and more comfortable or in a more walkable area than a typical industrial park.
This becomes more obvious when you leave the rich tech bubble of SF.
As the existing startups have proven, there’s no market for individuals renting houses to work from, the economics don’t work. A day pass at WeWork is cheaper than every listing on Vrumi.
I was thinking AaaS -- Aviato as a Service.
Thanks!
