As of November 2014, Smartsheet is used by 5 million people at 55,000 organizations. It was initially unpopular until a redesign in 2010, which was followed by an increase in adoption and larger funding rounds. Smartsheet is used to collaborate on project timelines, documents, calendars, tasks and other work. It combines some of the functionality of Microsoft Excel, Project, Access and Sharepoint. It competes with Microsoft Project. As of November 2014, there are 5 million users of Smartsheet at 55,000 organizations. According to Forbes, Smartsheet has "a relatively simple" user interface. The interface centers on "smartsheets," which are similar to spreadsheets typically found in Microsoft Excel. Each smartsheet can have its rows expanded or collapsed to see individual tasks or large-scale project progress respectively. Tasks can be sorted by deadline, priority or the person assigned to it. If a spreadsheet contains dates, Smartsheet will create a calendar view.
