We're the creators of Highrise, now featured in the iOS App Store with 50 million users and rapidly growing. We're building bleeding-edge technology for developers and amateurs to create immersive experiences and worlds inside our virtual universe.

We believe that the future of virtual worlds is bright, and we're excited to be at the forefront of this industry.
