We're pleased to welcome Gregor Stewart as an advisor to the Pydantic team.
Gregor is Chief AI Officer at SentinelOne, where he leads AI strategy, platform, product and research. He also advises Insight Partners and a number of other AI companies. He's spent his career at the intersection of AI and production systems, at the kind of scale where the gap between a good idea and something you can actually rely on becomes very clear, very fast.

That's the problem we think about every day. Developers building AI applications need infrastructure they can trust. Not infrastructure that works in demos. Infrastructure that holds up in production, under load, across teams, over time. Gregor's experience doing exactly that, in cybersecurity and applied ML, makes him a genuinely useful voice as we keep building.

> "Gregor's experience across AI systems, research and enterprise adoption will be hugely valuable as we continue expanding Pydantic Logfire and the stack."
>
> Samuel Colvin, Founder and CEO

Welcome, Gregor. We're glad to have you as our advisor.
