Yonja, a Turkish social network, has raised a big $12.5 million round from Greywolf Capital Partners and Tiger Global Management, reports PE Hub. The site claims to be Turkey’s largest social net, with 4 million registered users. Along with standard social networking features, the site offers casual games and videos. Yonja is a division of Yonja Media, which has offices in Istanbul and San Francisco, and more than 20 employees. Yonja media has previously announced the sale of minority stakes to Greywolf and Tiger (see here), so it’s not clear how this round fits into those prior investments. We haven’t heard back on a request for clarification.
