VietBank CIO on Agentic AI, Homegrown Innovation, and Why Vision Beats Scale

Overview

I recently had the immense pleasure of sitting down with Nghia Tran, the immediate past Chief Information Officer of VietBank (effective 1 June 2026). With 26 years of IT leadership and just over two years in his current role, he has reframed what IT means at a mid-sized Vietnamese bank - a strategic engine. Our conversation covered:
 
Build in-house, because the data cannot leave the building
VietBank's flagship AI innovations, such as the Smart Office Tracking System (SOTs) and Intelligent Management System (IMS) were built entirely in-house using open-source components, including a self-hosted LLM, rather than procured from enterprise vendors. The reason is non-negotiable - sensitive banking data must never leave the bank's environment. Delivered in just three and a half months on a lean budget, SOTs cut document approval cycles by 35%, earned VietBank an ASEAN Innovation Award in 2025, and drew an invitation from the Vietnamese government to present at the National Digital Governance Conference.
 
Deploy AI now, do not wait for perfection
Nghia Tran's philosophy is refreshingly pragmatic: identify a specific use case, run a sandboxed MVP, prove value, then scale. "If we keep waiting for perfect data, we fall behind our competitors," he shared with me. It is a discipline applied to the urgency of a fast-moving market.
 
Cybersecurity is the sector's most underappreciated risk
Vietnam ranks among the top global targets for cyber-attacks, and Nghia Tran was direct. AI-powered threats are moving faster than legacy security architectures can handle. His approach is multi-layered - red teams, penetration testing, national agency collaboration - but his broader concern is systemic. A supply chain attack on one bank, he warned, can cascade through the entire financial system.
 
The fintech answer is intelligence, not spend
Against MoMo's 40 million users and the rise of neobanks, VietBank is not trying to out-spend the competition. Instead, Nghia Tran is investing in AI-driven customer intelligence such as behavioural analytics, CRM integration, and personalised upsell - anchored by the newly launched DigiBiz SME platform and a refreshed mobile banking app, with payments and trade finance integrations on the roadmap.
 
The constraints are real
When I asked what could derail his vision, Nghia Tran shared that hardware costs doubling and tripling as AI chip demand surges globally, organisational alignment risk if business units don't sustain adoption and talent retention are the hardest of all. His solution to the last one is culture, which is to give people autonomy, let them grow and make the work worth staying for.
 
The key takeaway for me is that the most powerful technology transformations do not always happen at the biggest banks with the deepest pockets. What Nghia Tran is building at VietBank with a lean team, a clear philosophy, and a genuine bias for action, is a reminder that vision and execution matter more than scale.
