WeiMai
微脉
WeiMai (微脉) is a Chinese "internet + healthcare" platform founded in 2015 by Qiu Jialin, who serves as CEO . The company positions itself as a "localized trust-based doctor-patient service platform," building city-level one-stop healthcare service networks through deep partnerships with public hospitals rather than bypassing them . By 2020, it had covered over 160 cities and partnered with more than 1,000 public hospitals, serving 700,000+ users daily with 10,000+ doctors offering 20,000+ medical service SKUs on its platform .
The company's core strategy centers on "trust medicine" — converting offline doctor-patient interactions at public hospitals into sustained online relationships, then layering incremental paid services atop that trust . It targets primarily third- and fourth-tier cities, which Qiu has described as a "rural surrounds cities" approach covering some 500 million people .
Source Code Capital has been WeiMai's most consistent backer, leading its angel round in 2015 and continuing through its A, B, and C rounds . Other investors include IDG Capital, Baidu Capital, Matrix Partners China, Vision Plus Capital, and Cenova Capital . The company most recently closed a RMB 200 million Series D in January 2025, with Source Code Capital again increasing its stake .
