Executive suites and small office leases have been around forever, but even those are going to want leases of 6 months to a year. Where they can really make sense is in a place where the building owner or leasing agent has suites run by onsite staff that they might have needed anyway.

My impression of We has been that it's coworking spaces (aka limited commitments) but "we're so trendy and hip that you'll stay at short term high rates even when you have a stable business and could get a regular cheaper lease elsewhere."

That or it's a long con.
