Only 27 percent of Ouya owners have bought games

Ouya CEO Julie Uhrman has confirmed that only around a quarter of customers who have purchased the device have also bought software on the company’s Android-based home console.

The news comes from an interview with The Verge, where Uhrman said that hardware sales and conversion rates shifting players from free demos to full version software--13 of Ouya’s top 20 grossing games have achieved an 8 percent upsell average--will continue to rise as more content is produced and the marketplace matures.

"I think there are a lot of social and mobile app developers that would kill for an 8 percent attach rate on a platform that's 30 days old," she said. "These numbers will grow as more gamers pick up consoles, and as we attract more developers, and I believe that by the end of the year, we'll see a few developers telling us they've made more than a million dollars on Ouya."

Uhrman also confirmed that interest from content creators is growing, with more than 21,000 developers now signed up to make games for the system, up from 8,000 in March this year, when Kickstarter backer units became available.

Earlier this week, TowerFall creator Matt Thorson revealed that the game has performed well, selling 2,000 units.

To help bolster its software library, Ouya has announced a $1 million "Free the Games Fund" that will match Kickstarter crowdfunding for original projects that will remain exclusive on the platform for at least six months.
