Online legal services company LegalZoom.com Inc. has added a new member to its board as part of an investment from a Silicon Valley firm. The amount the Glendale company received from Technology Crossover Ventures in Palo Alto was not disclosed. In addition to receiving money, David Yuan, a general partner at the investment firm, has joined the LegalZoom board of directors. LegalZoom Chief Executive John Suh called Yuan a strategic thinker with a deep understanding of small and medium-sized business subscription models. “LegalZoom is empowering millions of small businesses and consumers with delightful products, experiences and services,” Yuan said in a statement. “We believe LegalZoom is the category leader and building an important and highly valuable technology franchise.” In July, LegalZoom received $500 million in funding from a group of four investors, including Francisco Partners in Menlo Park and GPI Capital in New York.
