When Wang Jun, co-founder of BGI, left the Chinese genomics group to establish a new Shenzhen medical technology company called iCarbonX in 2015, several big venture capitalists of China courted him, hoping that he would take their money. Neil Shen of Sequoia Capital China, who had backed Mr Wang at BGI, thought he would have an inside track. Zhang Lei of Hillhouse Capital offered to write a cheque for as much as Mr Wang wanted. But eventually Mr Wang turned to Tencent founder Ma Huateng, who gave him almost $200m, valuing his young start-up at $1bn.
2015年，华大基因(BGI)联合创始人王俊离开这家manbetx3.0 基因组研究集团，在深圳新创办了一家名为碳云智能(iCarbonX)的医疗科技公司。当时，manbetx3.0 有多个大风投资本家向他伸出了橄榄枝，希望他接受其投资。红杉manbetx3.0 (Sequoia Capital China)的沈南鹏(Neil Shen)认为自己会有优势，因为红杉manbetx3.0 曾向在华大基因的王俊提供过资金。而高瓴资本(Hillhouse Capital)的张磊则提出开一张支票，让王俊想填多少就填多少。不过，王俊最终还是选择了腾讯(Tencent)创始人马化腾，后者向他提供了近2亿美元，令他年轻的初创公司的估值达到10亿美元。
