Jensen Huang of NVIDIA said that he searches for hard problems, solves them, then tries to forget how difficult it all was. “It must be the feeling that marathoners go through … the entertainment value of pain and suffering can’t be understated.”I guess that's why we do startups.

Alohar Mobile is Ambient Intelligence. Backed by the most successful investors in Silicon Valley, including Tim Draper, David Cheriton (Professor Billionaire at Stanford, first investor in Google), etc.We are building a new generation of intelligent smart-phone applications and mobile behaviour services. Many fantastic applications have been built on top of Alohar platform. For example, MileIQ built its automatic mileage expense system on Alohar's intelligent tracking platform. MileIQ was acquired by Microsoft by a big price in 2015.Acquired by Autonavi and Alibaba in 2013.

Work with Tim Draper, Joel Yarmon, Bobby Chao, Josh Stein, Andreas Stavropoulos and other great guys at DFJ to incubate Alohar Mobile.
