Zendesk, which provides customer service software, has announced three appointments to its board of directors, as the company is reportedly moving closer to quietly filing registration papers for an IPO. Zendesk, which is located in the mid-market area of San Francisco near the headquarters of Twitter, Square and Uber, has raised $70 million in venture funding and a $15 million Series D debt facility since its founding in 2007 when it was based in Copenhagen, according to data from Thomson Reuters. Investors include Benchmark Capital, Charles River Ventures (which is the only venture firm to have participated in all of Zendesk’s funding rounds), Goldman Sachs, GGV Capital, Index Ventures, Matrix Partners and Redpoint Ventures. In 2010, Thomson Reuters data shows that the company was valued at $159 million for its $19 million Series C round. Zendesk could not be reached for comment.
Update: The description of Zendesk was changed to make it more clear what the company does.
