iCarbonX, a Chinese health-related data mining and analysis firm, has joined a $8.4 million Series B financing round in HealthLoop, a California-based platform for automated doctor-patient interaction.

iCarbonX plans to integrate HealthLoop’s patients-generated data to advance its data mining technology and help establish its digital life ecosystem. Meanwhile, the American company will use the Series B funding to expand its market and enlarge its business teams.

Founded by Dr. John Shlain in 2009, HealthLoop helps to digitally connect patients with their doctors and care-givers. The platform is designed to keep track of patients’ illness and uses analytics engine to provide real-time analysis. It claims to facilitate over 500,000 patient interactions every month.

Established in October 2015, iCarbonX took only six months to achieve a $1-billion valuation and become the world’s fastest unicorn after Tencent Holdings led a RMB1-billion ($155 million) Series A round in April 2016.

Jun Wang, founder of iCarbonX stated that the investment in HealthLoop is in line with our strategic planning. The big data era of life sciences has just been launched, whereas a lot of previously dismissed healthcare data has just begun to show its significance. The HealthLoop platform has done an excellent job in connecting patients and doctors, tracking patients’ recovery process and mining patients’ data. All of these are essential components of iCarbonX’s digital life ecosystem.
