I continue to have conversations with people who are not based in NYC and they are always surprised to hear that the NYC startup scene has startups in various sub-sectors.  When people think of NYC startups, they typically think of AdTech or Digital Media or Commerce.  As you can see below, there are many sub-sectors that NYC startups are gravitating to.
