The work developed reports the internship carried out within the scope of the master’s in management, in a software development consulting company based in São Paulo, Brazil. The internship focused on the creation and automation of ZRP's marketing department. The report explains the entire process that led to the creation of the department, presenting the objectives proposed by the company at the beginning of the internship, and all the steps that was necessary to go through so that the department was successfully created and maintained. The main objectives were the definition of a marketing strategy, the development of the marketing mix, and the creation of a communication base and the company's first campaign. To achieve the goals, it was necessary to reassess the company’s purpose, developing a new mission, as well as a vision statement. Besides that, the values that guide the company’s purpose and behavior were cleared out in the form of statements. With that basis, it was possible to design a market segmentation and, from that, choose a target market and define the firm’s positioning. Then, we focused on product and price to design ZRP’s first marketing mix. Finally, the company’s first communication campaign was designed under the 6M framework and successfully launched and monitored according to a set of KPI’s. Under this campaign, 16 social media pieces were posted, reaching an audience of more than 16 thousand users. All the objectives were achieved, and the work developed during the internship created a base that allows the updating of the strategy and the regular creation of new communication campaigns.
