Orchard is still a fairly young company. We launched our selling service in March of 2014, which we count as our official birthday. You can read the original announcement post here and the follow-up announcement here!
Before then, Orchard was mainly a utility app that iPhone users could download to find out the Fair Market Value for their iPhone, with the hopes that they would secure their own sale. We spent this time perfecting our service before actually buying and selling iPhones ourselves.
