Somewhere along the way I think we got it flipped around. No one was calling Sears a tech company in 1969 just because they bought an IBM 370 to computerize their accounting and inventory. By probably 1975, if you were Fortune 500 and still doing your books by hand you were probably just a dinosaur rather than your computerized competitors being so advanced.
Uber, Tesla, okay, maybe there is an argument to be made for them to be "tech companies". Like the referenced investors, I fail to see how WeWork is anything but a real estate play, and consequentially having to work from that rulebook. Oh, you have computer systems involved? Welcome to the 21st! Where everyone else does, too.
In summary, I don't think simply using a phone app to do some form of collaboration or logistical deployment using assets owned or contracted by the company qualifies one as a "tech company" anymore. I think they're still a traditional company doing what everyone else ought to (and eventually will) be doing to begin with.
