Zendesk, founded in 2007, develops Web-based help desk and customer support applications the company said goes beyond the traditional "trouble ticket" approach to communicating with customers. Zendesk's software, now used by more than 5,000 companies, helps businesses communicate with customers using multiple channels. "The true voice of the customer is increasingly social," said Maksim Ovsyannikov, Zendesk product management vice president. Recently Zendesk integrated its software with Twitter, allowing customers to monitor feeds for comments on their products and pull them into Zendesk, and developed links to data generated by Salesforce.com's CRM app.
