Nuek, the Indra Group’s payments-focused technology company, announces a new phase in modernizing its payments platform, based on incorporating generative AI capabilities and evolving toward a cloud-native architecture built on Google’s Cloud technology ecosystem.
The project responds to one of the sector’s major challenges: operating payment services that are increasingly critical, with higher transactional volume, greater availability requirements, and a growing need for operational efficiency. In this context, Nuek has evolved the technological backbone of its platform, adapting more than six million lines of code to an architecture prepared to support new business models, absorb higher transactional volumes, and accelerate the deployment of capabilities across different markets.
“We are building a new generation of digital payments capabilities: more resilient, smarter, and prepared to scale internationally. The combination of cloud and generative AI allows us to evolve Nuek’s operating core and move toward a company capable of turning technology, knowledge and data into real advantages for its customers,” explained Javier Rey, CEO of Nuek.
Generative AI at the service of operational efficiency
Nuek Intelligence is presented as a platform that centralizes knowledge, automates processes, and lays the groundwork for a network of intelligent agents capable of integrating with different corporate environments, driving a more efficient, autonomous, and scalable operating model.
Based on a Retrieval-Augmented Generation (RAG) architecture, the solution works directly with the internal knowledge of organizations, from technical documentation, contracts, costs or incidents, guaranteeing contextualized, traceable, and operation-aligned responses.
Additionally, Nuek Intelligence relies on Google’s Gemini models, deployed through the Gemini Enterprise Agent Platform, and on advanced semantic search capabilities, enabling it to interpret large volumes of information in real time and facilitate decision-making in highly complex environments.
Its day-to-day impact is already visible. The platform automates incident classification with 89% accuracy, reduces the time to locate critical information by 67%, and improves operational efficiency by around 35% across various business areas. It also enables immediate analysis of the impact on critical systems, accelerates code generation, and optimizes knowledge management in highly specialized teams.
“In a payments company, operational knowledge is a critical asset: technical documentation, incidents, costs, contracts, systems and processes that must be interpreted quickly and accurately. Nuek Intelligence enables us to activate that knowledge through generative AI to make better decisions, accelerate responses, and strengthen the efficiency of our operation,” said Javier Rey.
Modernizing a payments platform without disrupting the business
One of the main challenges of technology transformation in payments is evolving critical platforms without impacting the daily operations of financial institutions, fintechs and retailers, nor the user experience. In this context, Nuek’s cloud-native architecture strengthens the platform’s availability and scalability without interrupting service, even in high-demand scenarios or during progressive deployments in new markets.
Thanks to this evolution, the company guarantees 99.99% service availability, can tenfold its capacity in seconds in the face of demand spikes, and deploy new capabilities more rapidly.
The modernization has been carried out in phases, keeping the platform running throughout the process to avoid interrupting the service. This approach has allowed the technology to evolve without impacting the daily operations of customers and users, preventing transaction losses during the migration.
“The market’s demands are increasing: payment services must always be available, respond in real time, and adapt to new volumes, customers, and markets without compromising operational continuity. The cloud-native evolution of our platform enables us to modernize the business without stopping it, strengthening resilience, elasticity, and international deployment capacity. On this foundation, cloud and artificial intelligence become two key levers to build a more agile, more efficient, and data-driven company,” added the Nuek executive (Indra Group).
