Today's guest is Matt Weaver, Head of Solutions Engineering for EMEA at OpenAI, working directly with some of the biggest names in financial services including Revolut, Alicabank, and BBVA.

Before OpenAI, Matt spent four years at a pre-ChatGPT AI company helping banks extract data from documents using traditional machine learning.

When ChatGPT burst onto the scene and disrupted everything he was working on, he knew there was only one place he needed to be, and he was fortunate enough to get the call from OpenAI, where he's spent the last two years building out the Solutions Engineering team across EMEA from the ground up.

In the full episode, we cover:

  • How AI has moved from pilots to production inside major financial institutions
  • What GPT-5.5 can do that the models couldn't six months ago
  • The highest ROI use cases in financial services right now
  • How OpenAI helps banks navigate regulation, compliance, and data residency
  • What AI agents actually are, and how long they can now run without human input
  • Why entry-level employees are outperforming tenured colleagues with AI tools
  • How to go use ChatGPT to it best of power


If you're in fintech, working inside a financial institution, or trying to understand how AI is actually being deployed at scale, this one is essential listening.
