Executive Spotlight: Barr Moses, Co-Founder and CEO of Monte Carlo (2027)
Barr Moses is the co-founder and CEO of Monte Carlo. Monte Carlo's own bio page for her is titled "Barr Moses, CEO & Co-Founder of Monte Carlo" and describes the company as the agent trust platform, so this is her current role on the company's official pages.
She matters because Monte Carlo is one of the best-known names in data observability, a field that Monte Carlo's author page says she created as a category. The company now frames its work around helping enterprises trust AI agents and the data that feeds them. In a May 2026 post she wrote, "Our mission is to enable the world's enterprises to adopt trusted AI."
Before Monte Carlo she worked at Gainsight and at Bain & Company. This page uses public professional information only.

Leadership style and philosophy
These points come from her own May 2026 post on the Monte Carlo site.
- Agents fail quietly. She wrote that traditional software fails loudly, while agents hallucinate, act on stale data or drift from the behavior you tested.
- Trust is built in. She wrote that trust is not a feature to bolt on after the fact and has to be built into every layer of the AI stack.
- Data and AI together. She argued that data and AI are two interconnected pieces of one system, so monitoring them separately shows only half the picture.
- Listening to leaders. She opened the post by saying she talks to dozens of data and AI leaders every week, and that their questions about trusting agents inspired the company's new direction.
