China-based startup incubator and early-stage venture firm Withinlink, founded by Bessie Lee, the former chief executive of WPP China, has launched a second $30 million fund focused on bringing American start-ups to China. The new fund comes after the firm closed a RMB fund last March targeting mid- to late-stage U.S. media and technology companies not yet doing business in China, as well as early stage companies founded in the U.S. by Chinese entrepreneurs.
