TECH CRUNCH - May 5 - Dating site Zin.gl was designed not to appeal to masses of users. Zin.gl instead aims for quality, not quantity, having developed a way to mine existing social networks such as Facebook, LinkedIn, Twitter and Foursquare for valuable ‘dating information’, and then feeding that data into its ‘social matching’ systems. People who sign up for Zin.gl will find compatible dating partners, with unquestionable real identities. Zin.gl was founded by Alexander Dresen, who previously started place.to.be, the first chat site in Belgium, as well as its first social network, LookNMeet. The company has raised $600K from angel investors.
