NVIDIA's Georgios Kolovos on Revolut's PRAGMA, Transaction Foundation Models & the Agentic Banking!

Is the "AI-native bank" a distant reality — or is it already here?

In this episode of Fintech Conversations & Insights, I sit down with Georgios Kolovos, NVIDIA conversations & Insights,'s EMEA Payments and Fintech Leader, to unpack what's actually happening at the infrastructure layer of financial services.

We go deep on Revolut's PRAGMA — the foundation model trained on roughly 40 billion banking events from 25 million users — and what it signals for the rest of the industry. 

We talk about why Transaction Foundation Models break the silos that have defined financial services for decades, why off-the-shelf models won't cut it for Tier 1 banks, and why Mastercard, Stripe, Adyen, Plaid, and Nubank are all building down the same path.

We also discuss:
✅ The impressive presence of financial services at NVIDIA GTC 2026 
✅ The "AI Factory" framework
✅ Why specialized models and Transaction Foundation Models are complementary
✅ How event-sequence data (not just transactions) is the real moat behind PRAGMA
✅ Whether a "Financial World Model" — a digital twin of an entire payments ecosystem — is fantasy or roadmap
