In this interview from Appian World 2026, Leonardo Vivas Muñoz, account executive for LATAM at Appian, joins Alejandro Arias, continuous value team leader and project manager at Bancolombia S.A., to talk with theCUBE's Dave Vellante and co-host Alison Kosik about how Colombia's largest financial institution is embedding AI into core banking workflows to automate document processing at scale. Arias opens by framing Bancolombia's reach — 36 million customers, 24,000 employees and about 50% of all financial transactions in Colombia — before detailing how the bank deployed a fully functional AI-powered processing system in just 13 weeks. That system now handles 80,000 documents per month with high accuracy. Vivas explains how the implementation unified fragmented databases and disconnected systems under a single Appian platform combining AI, RPA and human-in-the-loop workflows, reducing time spent on manual processes by 70%. The conversation also explores how Bancolombia treats AI transparency not as a feature but as a governing principle. Arias is direct: if a decision cannot be explained, AI cannot be involved in it. Full audit trails, confidence scores and end-to-end traceability are mandatory for every document that passes through the platform. Vivas connects this to Appian's process intelligence capabilities, noting that embedding AI within the process — rather than alongside it — protects data integrity and reduces human error. The discussion also examines the broader adoption landscape, where Arias warns that financial institutions rushing to deploy AI without a process-centric foundation are making costly mistakes. From managing the operational complexity of a 115-year-old institution to envisioning a future where Bancolombia shifts from reactive banking to anticipating client needs in real time, the interview illustrates how trust-first AI governance is becoming a competitive advantage in highly regulated markets.
