Brazilian Digital Bank Sees ChatGPT as an Ally in Four-Day Workweek

Since its launch, ChatGPT has attracted the attention of professionals from various fields. Efí, one of the leading Brazilian fintechs, has gone further and started using the system to optimize processes. A fan of the four-day workweek, the company identified a reduction of up to 40% in time spent on activities.

For Efí’s CRM manager, Alexandre Santana, despite what some analysts believe, ChatGPT will not replace professionals but will make processes more fluid, objective, and modular, thus reducing potential manual errors. “In our tests, the intelligent use of AIs allowed us to perform tasks in minutes that would otherwise take hours. I have no doubt that the ability to use these tools will be a requirement, especially as this technology evolves,” he says.Less operational, more strategic 

Since implementing its reduced workweek for nearly 400 employees, aiming for a better work-life balance, Efí has placed even more value on task optimization. Using ChatGPT to generate code and for routine tasks, such as drafting emails and creating project scopes, complements other initiatives, like reducing meetings, to make day-to-day operations more strategic.

With the use of ChatGPT, developers gain extra time to work on more sophisticated tasks and leave the creation of smaller and more basic codes to the tool. In any case, caution is needed with the generated codes, warns software engineer Leony Assis. “It is important to review the codes to ensure 100% accuracy. Therefore, the objective of the software in development, as well as the technologies involved, must be fully understood.”

Efí concluded that AI can even be used to generate ideas from user feedback, providing a better understanding of what they need, and identifying the best components and structures in the system architecture phase.

Specializing in financial solutions, Efí is a payment institution with 370,000 clients across Brazil, and is responsible for moving over $4 billion every year. The company was authorized by the Central Bank of Brazil to operate as a Payment Institution and Acquirer and is a direct participant in Pix, the Brazilian instant payment platform, and a payment initiator in Open Finance.
