    The Client: A Century of Financial Leadership

    Founded in 1906, The Bank is the largest private financial institution in Ecuador, with a century-long legacy serving millions of customers across Latin America and Europe. Despite their strong market position, the rapid shift to digital banking and heightened customer expectations created an urgent need to modernize their technological foundation. They sought a trusted partner with proven global standards and agile expertise to drive this ambitious transformation.

    The Challenge:
     $80M Annual Loss and System Fragmentation

    The Bank faced critical hurdles that threatened their competitive edge, resulting in significant financial drain:

    Key issues included:
    • •Massive Technical Debt: The IT ecosystem contained 300+ internal applications, some decades old, undocumented, and costly. The bank was losing up to $80M annually due to pervasive inefficiencies and downtime.
    • •Low Uptime: Uptime dropped significantly below the 99.9% industry benchmark, resulting in service disruptions and customer dissatisfaction.
    • •Stalled Modernization: System dependencies were unclear, and a staggering 35% of apps were redundant or obsolete, yet no centralized inventory existed to safely
    • •Operational Inefficiencies: Legacy notification systems were rigid, lacked multi-channel support (Email, SMS, WhatsApp), and struggled with scalability.

    "VeIX delivered results fast—but the real value was the clarity it gave our teams.

    For the first time, we understood the full scope of our systems and had the confidence to modernize without risking operations."
