Due to its low costs and wider reach, Twitter is a relevant tool for small companies to be used as a promotion vehicle and can be used to understand what companies are interested. This paper presents a case study on the visualization of the activity of several known Portuguese startups in the Information Technology area of business. We performed a content categorization of their posts in order to understand what themes are addressed and concluded that companies share a similar content distribution. Moreover, a visualization of their Twitter followers and following communities have also been explored, showing that, as expected, their social communities overlap.
