Most people only know Match Group as the owner of some of the largest dating apps and websites, such as and Tinder.
But it's also the owner of Princeton Review, the popular test prep and tutoring service, after acquiring the company last year.
For those wondering, Match Group explained it a bit in its S1, which was filed Friday as it gears up to go public soon.
Here's what it said: We acquired this business because it relies on many of the same competencies as our dating business, such as paid customer acquisition, a combination of free and paid features, deep understanding of the lifetime values of customers, and strong expertise in user interface development.
With the appointment, Mr Koo brings to Paktor Group more than 10 years of executive experience working with both public and private companies across the digital and financial sectors.
