William Dai is the Founding Managing Partner of ShangBay Capital, an early-stage Medtech-focused venture capital firm based in Palo Alto, California. He founded the firm in 2015 and has led it to build a portfolio of 60 companies with multiple successful exits. ShangBay Capital primarily invests in early-stage medical technology ventures, with a focus on the Medtech sector and operations centered in the United States, particularly California.

His notable portfolio includes companies such as Luminopia, SetPoint Medical, Aqua Medical, and Emboline, many of which he serves on the board of.
