The general strategy must be undercut the market to buy market share, and then transform the market entirely.

I don't understand the precise mechanisms in the case of WeWork (it's not as clear as, say, Uber + self driving cars). Can someone explain?

They bought Meetup recently so maybe they are planning some sort of synergy?

I just received an email from them touting the ease with which I can rent space from them (free for some introductory period) for the meetup I run. The problem is that many (most, I'm guessing) meetups are funded by an individual. Unless their space is drastically less expensive than a lot of the alternatives I found when trying to find a space for my meetup, nobody is going to be able to afford to use their space.
