Accelerators are organisations focused on leveraging technology-based companies, especially scalable businesses. However, there is little reference to their structure and hierarchy. The reason for this scarcity is that they are recent organisations, the first appearing in the United States in 2005, and in Brazil only in 2008. The aim of this study was therefore to develop a proposal for an organisational structure for an accelerator for technology-based companies. The methodology adopted was bibliographic reference research on key subjects such as: innovation habitats; organisational structure models. In order to provide the knowledge needed to draw up the organisational structure proposal. The result was a proposal for an organisational structure for an accelerator of technology-based companies, based on the team organisational structure model. The proposed model will serve as a guideline for structuring new accelerators, or even adapting existing ones.
