Social network with matchmaking, with 110,000 users in a year worldwide. The concept aims to completely change the way people meet online. Goodwizz combines Facebook functions (friends, search, chat, photos, profile, etc.), with matchmaking services (matchmaking algorithm), and adds personality games to interact with people online. The differentiation lies 1) The combination of full social network and matchmaking 2) The addition of trying to go beyond first contact with personality games and psychology (personality games made with psychologists enable people who want to discover each other better). The website needs a better design, easier navigation and some better code in some areas. It can be a great alternartive to existing websites and can offer a better way to connect and know people online.
