Teemu Kurppa, a mobile software developer and a member of the founding team of the activity stream and micro-blogging service Jaiku, is leaving Google. He joined Google with the rest of the Jaiku team when Google acquired the startup in October 2007.

In his blog, Teemu tells that the main driver for his departure was an illness in his family which subsequently brings him back to Helsinki, Finland. However, he is up beat about seeing his loved ones back in Helsinki and also mysteriously comments that: “on work related matters, I’ve some exciting plans. More about these later”.

ArcticStartup wishes the best to Teemu and his family and excitedly expects whether Teemu will set up a new mobile startup when he moves back to Helsinki. Welcome back to the Arctic region Teemu!
