In 2004, David noticed LCD screens popping up on office buildings near where he lived. He did some investigating and discovered the source of the screens: Focus Media. He reached out to the company’s founder, Jason Jiang, and after confirming that the company’s fundamentals were strong, David invested in the company. “Timing is very important,” says David. “If I didn’t see the product from the Chinese consumer’s perspective, I would have missed the opportunity to invest in such a great company.”

David studied in the United States, graduating with a masters degree in biotechnology and business from Northwestern University. After earning a bachelors degree in clinical science with a minor in chemistry from California State University, San Francisco, David spent three years working in the Department of Urology and Department of Neurology at the Veterans Affairs Medical Center at UCSF.

David then moved onto ABN AMRO Capital, where he was a senior venture associate responsible for developing and executing acquisition strategies for life sciences, information technology, and Internet companies.

David joined WI Harper in 2001 as an associate in the San Francisco office and moved back to China in 2002, where he eventually became the managing director of the Beijing office for WI Harper. In that role, he oversaw the firm’s investments, portfolio management and operations in life sciences and technology in China. He invested in a number of leading companies, including Focus Media.
