DEUTSCHLAND RUNDFUNK - Sep 29 - Ignighter, a group online dating site, started as a Facebook app. Adam Sachs and his two friends created Ignighter app for Facebook after their negative experiences with traditional online dating. Ignighter got over 1M funding in 2008 and became the leading group dating site. Unlike other dating sites, Ignighter's members can only communicate within groups. Adam Sachs now has to figure out how to generate revenue since most of Ignighter's members came from Facebook and are used to the free service. Parship.de, a personality profiling dating site, doesn't have to worry about generating revenue. This company has been around and charging for their services for over 10 years now. Members have to fill out 200-question questionnaire before they receive their first match. The site claims that over 10K people sign up a day. FULL ARTICLE @ DEUTSCHLAND RUNDFUNK (in German)
