With ia.i, a conversational interface, and the IARA governance platform, Itaú is applying its AI First strategy to customers and employees — in one of Brazil’s most regulated sectors.

of the customer base is the goal by the end of 2026

Creating a close, personalized experience for millions of customers in a country like Brazil is, first and foremost, a question of simplicity rather than of models.

“Much of it is about making something simple, direct, and useful, delivering a direct benefit to the customer, and making the technology almost unnoticeable,” says Carlos Eduardo Mazzei, CTO of Itaú.

The standard he describes is demanding: the solution must solve a real everyday problem and be direct, simple, and memorable. Technology serves as the means, never as the centerpiece of the experience.

There is demand for this. A study by Itaú in partnership with Grupo Consumoteca shows that 80% of Brazilians want to better organize their financial lives and seek more effective support for decisions, and that 65% would like technologies that act as a financial copilot, providing ongoing guidance.

The journey began in 2024, when the bank introduced the first Inteligência Itaú capabilities for specific financial needs. ia.i is the next stage: a complete conversational layer, activated by text or voice, bringing interactions related to checking accounts, credit, cards, insurance, and other services into one environment — and connecting customers to specialized human support whenever needed.

“OpenAI’s models were very important in delivering this experience, because they were able to operate across this range of solutions,” Mazzei explains.
