We're not at WeWork because of hype, or the image of the CEO, or anything like that. We're at a WeWork because it's a cheap/easy way to get an office, that we can scale when the company grows with minimal issues since it's month to month. We shopped around a few competitors, WeWork happened to be the best combination of price vs. space vs. availability, so we went with that.
I haven't exactly done a poll, but I doubt that most WeWork customers know or care about WeWork's culture too much - they just need an office, and WeWork is providing a cost-effective solution. Maybe it's artificial because of VC money - if so, I certainly don't care - it'll be good while it lasts!
For contrast: at my previous company, we also wanted to move to an office (instead of working out of my apartment). We spent a huge amount of time looking at offices, and ended up staying put, because it was hard to find a decent office with a decent price, and signing up for a 2-year lease is a huge commitment which is not fun to make when you don't know the future size of the company - do you get lots more space than you need and pay extra? Do you get less space and are in a tough spot if you grow too fast?
