Joel Julkunen is vice president, games at GameRefinery by Vungle. He has been playing games on various platforms ever since he could hold a NES 8-bit controller. Nowadays he leads GameRefinery’s analytics department and has a major role in developing the algorithms and statistical models used in the company. Fortunately for him, this means that he can dedicate a big chunk of his time to analysing new games and mapping interesting features for GameRefinery’s database. With over 500 mobile games played and analysed, Joel has a pretty good idea about the “do’s and don’ts” as well as trends of today’s mobile game market.
