Zendesk

Zendesk sells cloud software for customer support, including ticketing, live chat, messaging, help centers and, more recently, AI agents, to businesses ranging from startups to large enterprises. Mikkel Svane, Alexander Aghassipour and Morten Primdahl founded it in Copenhagen in 2007 and built the first version in Svane's loft. It reincorporated in Delaware in 2009, moved first to Boston and then to San Francisco, where it is headquartered.

German angel Christoph Janz, who later co-founded Point Nine Capital, put in about $500,000 of seed money in 2008. Charles River Ventures, through Devdutt Yellurkar, led a small Series A in 2009 that came with the condition of moving to the US. Benchmark and Charles River provided a Series B of about $6 million, and Peter Fenton of Benchmark joined the board. A $19 million Series C followed in December 2010, a month after Dana Stalder of Matrix Partners joined the board. In September 2012 Zendesk raised $60 million in a Series D whose venture portion was led by Redpoint Ventures, with Index Ventures, GGV Capital, Goldman Sachs, Charles River, Benchmark and Matrix, plus $15 million of debt from Silicon Valley Bank. The S-1 shows preferred stock liquidation preferences of $1.55 million, $6 million, $19 million and $45 million for Series A through D.

Zendesk priced its IPO on May 14, 2014 at $9 per share on the New York Stock Exchange under ZEN, raising about $100 million at a valuation Wikipedia puts near $1.7 billion. At filing, Charles River held 24.5%, Benchmark 18.7% and Matrix 8.8%, and all three bought more shares in the offering. Revenue rose from $38 million in 2012 to $72 million in 2013 and about $500 million by 2018. After shareholders rejected a planned purchase of SurveyMonkey's parent Momentive in 2022, Zendesk agreed in June 2022 to sell to an investor group led by Hellman & Friedman and Permira, closing on November 22, 2022 at $77.50 per share in cash, about $10.2 billion. As a private company it has continued buying AI businesses, including Forethought in March 2026.

Zendesk is a case of a small venture raise producing a large outcome: about $86 million of venture capital, then a public market path, then a private equity buyout at more than six times the IPO valuation eight years later. Charles River and Benchmark, which entered at Series A and B, held large stakes into the IPO, and the 2022 deal shows private equity as a liquidity route for mature SaaS companies.
