Yitu's apps give security the technological edge

Zhu Long remembers clearly how he got the first order for his company Yitu Technology, a Shanghai-based startup focusing on computer vision technology.

That was 2012 when Zhu, a postdoctoral fellow at the Massachusetts Institute of Technology, just returned to China. He chose the security industry as the starting point to build his own business.

But with no clients and without any background in industry, Zhu ran into trouble - until he managed to have a three-minute conversation with a deputy chief of a public security bureau in a Chinese city.
