to manage and monitor the construction of the Olympic arenas, and Jesuíno and Barizon, responsible for the development of a Portal of Management of these Olympic Works. The project's difficulties, common to several others, especially in the effective communication of the team, made it possible to improve the management of work in a more collaborative way and to make the communication of teams flow, making life easier for all and avoiding decisions could be taken unstructured, through exchanges of emails and messages through the mobile phone. In this way, throughout 2015, a prototype was created and presented to a group of investors, who bet on the idea. Thus, ZEHNK took shape and attracted a second round of investments for its evolution. This new stage began in March 2016, already with the team working totally focused on the project and with the use of the product by some "beta-users". At the beginning of September 2016, the commercial version of ZEHNK was ready and launched through a digital marketing campaign. Since its launch, ZEHNK has been attracting a growing number of users and companies, which has been multiplying every month, with extremely positive feedback.
