"The Most Photogenic
Based on Snappr Photo Quality Score"
Interesting site regardless
EDIT: And here come the downvotes, so let me clarify my stance. I haven't a clue what Snappr does, or what their definition of 'photogenic' is. But here is the dictionary definition of 'photogenic':
(adjective) (especially of a person) looking attractive in photographs or on film.
"Score between one and 100 based on an analysis of all photos on the company's homepage. Source: Snappr."
OH BOY IT'S SNAPPR! This is probably not biased.
 YCDB is made in San Francisco by the team at Snappr, which is a YC company (W17). Why? Because we love YC companies and discovering new ones! Edited by Matt Schiller.
How long as it been since a big, recognizable brand hit?
