Opens office and appoints regional head to develop key BRIC region.
InMobi is the world's largest independent mobile ad network, with over 93.4 billion global advertising impressions in January 2012.
The firm famously received a $200m credit line from Softbank last year, and is now embarked on a programme to position itself for the next wave of mobile ad expansion.
Russia is an obvious target given that InMobi's network served over 635 million mobile ad impressions in the country in 2011, almost five times more than 2010.
So it's opened its first Russian office in Moscow and hired Evgeni Agronik as general manager, Russia and CIS. He joins from AlterGeo, a Russian mobile location-based social network.
Agronik said: "Russia is one of the biggest internet markets in Europe, with more than 50 million internet users and 27 million mobile internet users.
"Despite this, mobile advertising is only just starting to become accepted by marketers and advertisers across the region. With smartphone penetration growing and 3G/4G (LTE) becoming standard, we are set to see an explosive growth in mobile advertising here."
