US fintech firm Fiserv has teamed with Microsoft to embed AI more deeply across its development platforms and global workforce.
The move underscores Fiserv’s broader push to integrate AI into its operations and products as competition intensifies across the fintech and payments landscape.
When a company that processes 90 billion transactions annually with a gross payment volume of $3.1 trillion decides to do this, it might be worth paying attention.
Since October, spending on AI across financial services has been projected to skyrocket from $35 billion in 2023 to $97 billion by 2027, and Fiserv wants to be part of the action.
Expanding AI across the workforce
As part of the initiative, Fiserv will deploy Microsoft 365 Copilot across its global workforce. The AI-powered assistant is intended to help employees work more efficiently by supporting tasks such as content creation, analysis, and decision-making.
In parallel, Fiserv is expanding its use of Microsoft Foundry, an Azure-based AI platform that allows organizations to build, customize, deploy, and manage AI applications. The platform is designed to support large-scale enterprise use of generative AI while maintaining governance and safety controls.
Taken together, the workforce deployment of Copilot and the expanded use of Foundry reflect a dual focus on operational efficiency and product innovation. By embedding AI tools directly into daily workflows and development environments, Fiserv is seeking to make AI a foundational capability rather than a standalone initiative.
Building on an existing AI foundation
The expanded relationship builds on Fiserv’s existing use of Microsoft’s AI tools. The company has already deployed GitHub Copilot to more than 8,000 software engineers, resulting in measurable gains in developer productivity. Fiserv has also made extensive use of Microsoft Foundry, processing more than 100 billion tokens to date.
According to the company, these capabilities have supported improvements across products, client servicing experiences, and its proprietary developer gateway. The scale of Foundry usage suggests AI is already deeply integrated into Fiserv’s development lifecycle, and the new collaboration is expected to accelerate that momentum.
The financial ecosystem
These implications stretch beyond productivity improvements. Fiserv’s market dominance makes this partnership a big deal for the entire financial ecosystem. Research from five months ago revealed the company commands a 42% market share of U.S. banks in core banking services and serves 31% of U.S. credit unions through its platforms.
This massive reach means AI integration will directly impact approximately 10,000 financial institution clients, six million merchant locations, 150 million deposit accounts, and 80 million U.S. digital banking users. When you process transactions at a median peak of 7,200 per second, even marginal improvements translate to enormous competitive advantages.
Fiserv’s recent acquisition of StoneCastle Cash Management, combined with AI integration, strengthens its ability to deliver data-driven services to financial institutions.
