Brazil's largest bank, @itau, deployed Devin across their whole SDLC. This is one of the largest AI agent rollouts anywhere in global finance. Itaú has 17,000+ engineers and hundreds of thousands of repos (yes, even COBOL). Even with that scale, they achieved results like: •

Working with an agent is a lot like working with a coworker - you need to know their strengths and weaknesses and you need to have a clear sense of how best to divide the work. So we gave Devin a performance review!
Devin, the AI software engineer, just got its 2025 performance review! Over the past eighteen months, thousands of companies have hired Devin, including Goldman Sachs, Citi, Santander, and Nubank. Using real-world examples and metrics from customers, we looked at where Devin

8/ Devin struggles with independently executing on ambiguous requirements. It needs clearly-defined requirements up-front.

5/ Another way Devin's grown over the past year is in codebase understanding. It's like having an on-demand senior engineer who’s been at your company for many years.

4/ Human developers averaged 30 minutes per SonarQube vulnerability; Devin averages 1.5 minutes. Devin migrated repos to a new version of Java in 14x less time than a human engineer.

3/ It’s great at critical but boring work like migrating repos, fixing vulnerabilities surfaced by static analysis tools like SonarQube and Veracode, writing unit tests, and completing small tickets.

2/ Over the past year, Devin’s gotten way smarter as a junior engineer - its PR merge rate has doubled as it’s developed better codebase understanding.
