At Banco CTT, innovation starts with people. When generative AI began gaining momentum, the bank wanted to experiment with business and technology side by side, but, as a regulated institution, it had to do so carefully. The result is Impulso 360: an internal app born in the business, rebuilt by InnoWave to enterprise standards in three months.
An idea born in the business, not in IT
Impulso 360 started in an unusual way for a bank. A business team used an AI tool to build, in less than a month, an app for employees to manage projects, activities, OKRs and learning. People tried it, liked it and kept using it.
That created what the bank calls “a good problem”: the app was too good to remain a prototype. In banking, working is not enough. Impulso 360 had to meet requirements for identity, security, quality and observability, as well as regulations such as DORA and GDPR. Shutting it down meant stopping a business-led initiative, but keeping it as it was was not an option.
Rebuilt to bank standards with VibeBuild
Banco CTT brought in InnoWave. In two weeks, InnoWave assessed the app and the verdict was clear: the value was real, but the technical foundation was not ready for a bank.
The team preserved every feature and rebuilt the foundation to Banco CTT’s standards using VibeBuild, InnoWave’s agentic development platform. AI agents accelerated the work, while every change required human approval.
“What gave me confidence was that nothing went through without a person approving it. We used a lot of AI, yes, but always with control.”
In three months, a single squad took Impulso 360 to enterprise level, in constant co-creation with the business and with around 3,500 automated tests validating every change.

The results
Impulso 360 is now an enterprise-grade product used across the bank:
- 400+ daily users
- 69% of activities completed on time
- 40 hours saved per month in reporting
“Impulso 360 is more than an app. It is the first product of a model we will certainly repeat. The next idea born in the business no longer has to choose between speed and security. With InnoWave, agents build and our teams decide.”
