For people in YC who are looking for places to work though and want to get out of their apartments I highly recommend the public libraries in Mountain View and the surrounding towns. They're quiet, well lit, have fast wifi, comfortable chairs and desks, and lots of nooks and crannies without much distracting foot traffic.
In the rare case of a successful startup, if the board doesn't replace the founder with an experienced executive, the founder probably has as much autonomy as corporate executive in charge of a successful division of a company.
Source: been there.
So the investor holds the lease.
That doesn't sound right to me (I've been in the YC network for 10+ years, as has dang), and is at odds with what tlb (an original and still-serving YC partner) said in this comment [1] above, and what has always been YC ethos.
Maybe the person who told you that was mistaken? Or it may have been a YC partner or staff member doing it privately?
