Charles Jo co-founded VLppl along with Johnson Hor, the genius behind Virtual Linkage. As a Silicon Valley recruiter in range of sectors — greentech, high tech, biotech/pharma, medical device, and social venture/non-profit sectors — VL became a natural extension of networking. He studied Psychobiology which to his great surprise became relevant in his later career. His interests are VLppl, job creation, technology impact on society, and games for business, education, and pure entertainment. StarCraft II 07.27.10. And animation … Futurama June 2010.
