OkCupid is an online dating company that offers a matchmaking service to all users, regardless of gender or sexual orientation. Matches are based upon the information users provide, and by their patterns of activity on the site. Users are able to browse through member listings, and rate them from one to five stars, the higher ranking indicating a better match. OkCupid uses these user-generated rankings, and will notify you if someone else ranked you as a strong match. The site allows for both free and paid accounts, and as of April 2013 they accept Bitcoin as a payment option.
OkCupid was founded by four former Harvard students in 2007, and is based in New York City. In 2007, Time magazine listed them among the top ten online dating sites.
