Fiserv said Devin will be used in core platform modernisation and in other engineering programmes.  

The system can handle work across large and complex codebases, allowing multiple engineering tasks to be carried out at the same time and helping bring new functions to clients more quickly. 

Fiserv co-president Dhivya Suryadevara said: “Speed matters more than ever in banking, and our clients are counting on us to deliver. With Devin, we can accelerate modernization of the platforms our clients run their business on, ship new capabilities faster, and free our teams to focus on the work that matters most.” 

Alongside the rollout, Fiserv is adding stronger governance and security measures for AI-assisted software development to safeguard the software lifecycle. 

The agreement is part of Fiserv’s wider plan to apply AI across technology operations and product development. 

Devin can perform end-to-end engineering tasks, including reviewing codebases, producing and testing code, and making further changes on its own.  

This will add to engineering capacity and allow teams to concentrate on improvements for clients, including software updates, stronger quality checks and better platform resilience. 

Cognition co-founder and president Russell Kaplan commented: “Fiserv is exactly the kind of organisation where Devin creates compounding value — massive scale and an engineering organisation that has ambitious goals for what it needs to build and maintain. 

“We are proud to partner with Fiserv to help teams deliver measurable improvements, so clients see faster access to new capabilities, more consistent releases, and continued focus on quality and security.”
