My previous employer at that time was a startup with about 100 people. Unfortunately the startup imploded (that was why I left) so I suddenly know about 100 people who were all working at different companies, mostly startups who needed to ramp up quickly. Working at some of those startups I got to know other people who liked my work, who eventually left for other companies, etc. (Admittedly "work for a startup which implodes" probably isn't reproducible advice.)
