Why does no one get that it takes lots of headcount to do ads and sales? According to another HN commenter they were pulling $170m in revenue and growing at a 30% rate. They had job listing ads from literally all the major companies and you need people to help close those deals. People seem to forget that you need big sales teams to build a huge advertising business. Even companies like Google with self serve advertising products have 1000s of employees because closing big advertising deals with corporations requires big sales and operations teams.
