Itaú Unibanco Selects Harness to Modernize Software Delivery Across Engineering Teams

Itaú Unibanco, Latin America’s largest private-sector bank, has selected Harness to overhaul its software delivery lifecycle. For fintech leaders, this move highlights the growing necessity for Tier-1 financial institutions to adopt autonomous engineering platforms that balance the speed of modern tech firms with the rigorous governance and security required in a highly regulated global market.

What was announced

Itaú Unibanco will integrate the Harness Autonomous SDLC Platform into its engineering organization to standardize how software is built and shipped. The bank, which manages millions of customers across digital banking, payments, and platform services, aims to utilize Harness’s capabilities in governed templates, automated verification, and policy-driven controls. This implementation is designed to provide faster builds and automated rollbacks while maintaining a consistent deployment experience across the bank's various programming languages and cloud environments.

The adoption follows an initial phase, with plans to expand Harness across the entire software delivery lifecycle. This includes building a unified foundation for visibility, control, and economics from code to production. A central component of the strategy involves leveraging generative AI within the engineering process to accelerate the speed and quality of software delivery. By automating the path from code commit to production, Itaú intends to reduce manual effort for its thousands of engineers, allowing them to focus on developing differentiating customer experiences. The roadmap is specifically designed to support the bank’s broader strategy of applying artificial intelligence across its engineering processes to meet the demands of modern financial services.

The companies involved

Itaú Unibanco is the largest private-sector bank in Latin America and a major player in the global financial services market. Headquartered in Brazil, the institution has a significant international footprint, providing a wide range of digital banking, payments, and wholesale services. The bank has increasingly positioned itself as a technology-driven firm, adopting modern infrastructure and engineering practices to compete with agile fintech entrants while managing the scale of a traditional incumbent.

Harness is a San Francisco-based company specializing in autonomous software development lifecycle (SDLC) platforms. Its technology is designed to help engineering teams deliver software quickly and securely through a suite of agents focused on security testing, runtime protection, and cost management. The company is backed by prominent venture capital and financial firms, including Goldman Sachs, Citi Ventures, Menlo Ventures, IVP, and Unusual Ventures. Harness’s platform is used by major global brands like United Airlines and Morningstar to optimize release cycles, with the company claiming its tools can accelerate releases by up to 75% and cut cloud costs by up to 60%.

What FF News has reported before

FF News has tracked Itaú Unibanco’s ongoing digital and international expansion. In late 2026, the bank made significant moves to streamline its global footprint by consolidating its European wholesale banking operations in Luxembourg. The bank has also been active in the digital assets space, notably through a partnership with OpenAssets to drive tokenization in Brazilian capital markets.

On the payments front, FF News reported on the bank’s collaboration with Swift to launch instant cross-border payments for Brazilian consumers. Furthermore, Itaú was involved in regional advancements in automated finance, as seen in Mastercard’s progress with agentic payments across Latin America and the Caribbean.

What this means

This partnership signals a shift in how incumbent banks view the "developer experience" as a competitive moat. By moving toward an autonomous SDLC, Itaú is addressing a common bottleneck in legacy banking: the friction between rapid innovation and regulatory compliance. The focus on generative AI within the delivery pipeline suggests that the industry is moving beyond using AI for customer-facing chatbots and toward optimizing the underlying machinery of finance. This puts pressure on other regional incumbents to modernize their DevOps foundations or risk being outpaced by institutions that can deploy secure, compliant code at the speed of a startup.
