A year is a long time in the mobile games industry.

Just ask Chartboost CEO Maria Alegre.

The San Francisco outfit, which was set up by a some Tapulous staff 12 months ago, is now 28 employees-strong and moving into an office space that will enable it to hit 60 before the end of the year.

And that's not the only impressive set of statistics, either.

Chartboost's cross-promotion and direct deals network is live in more than 8,000 mobile games, with its fullscreen interstitial ads now being shown in four billion game sessions (one ad per session) every month.

The all-important reach in terms of audience is more than 105 million uniques per month, while developers and publishers such as Backflip, Crowdstar, Disney, Gameloft, Get Set Games, GREE, Kabam, Kiloo, Playfirst, Pocket Gems, and TinyCo are making the most of the opportunity.

Happy birthday

"One year out Chartboost is not just independent, profitable, and rapidly growing, but we are taking market share away from traditional mobile game ad networks," said Alegre.

"More than any of our competitors, we know games and we know developers. We know how developers work, how games monetise, and how users discover new, great games. This has set us apart and we look forward to continue leading the industry."

The company has also recently boosted its staff in the Asia Pacific region, with new hires in China, South Korea, and Japan.
