Other leading websites, like Friend Scout24, are enjoying similar success despite targeting mainstream Internet users.Profits at online dating sites have increased in recent years as more and more singles turn to the Internet to find a partner.But with over 2,000 sites to choose from, the industry could be in danger of oversaturation.
"Germans like to pay not by credit card, but by bank transfer," Wiechers said.
"All the American companies came to Germany and invested millions in ads, but in the end they forgot that Germans like to pay by bank transfers so half of the people just didn't pay and they made a big loss.
Another downfall was when US companies asked Germans about hobbies like baseball or American football.
Every month around 7 million German singles are active on online dating portals, which range from personal ad platforms to full-fledged matchmaking services.
And with over 2,000 German online dating sites, it would seem that these singles are spoiled for choice.
This, however, isn't necessarily the reality as the public loses track of which sites are actually useful, according to Henning Wiechers, CEO of Singleboersen-vergleich, an online portal that rates dating websites in Germany, Austria and Switzerland.
"One site buys another one, and others go under; they're not able to continue with their marketing expenses because they don't earn enough," he said.
Similarly, German companies have made few inroads abroad, which makes holding ground in the domestic market all the more important.
Carving out a niche like Hamburg-based Elite Partner is one way of ensuring a healthy bottom line.
