Expensify x Braintrust 101: Active Observability
Braintrust 101 for Expensify
Join us for an introduction to Braintrust, open to technical and non-technical teammates.
Whether you’re building agents or working with the teams behind them, we’ll cover how to understand what’s happening in production and find opportunities to improve.
We’ll walk through:
The basics: what a trace is, how to read it, recognize good and bad behavior, add annotations, and use scoring to monitor performance
How to use Loop, our in-platform agent, to investigate user interactions, build evaluations and scorers, and set up automations using natural language
How Topics and Patterns help your team surface recurring issues, investigate root causes, and decide what to address in your next PR
How to bring it all together so Expensify can turn production insights into improvements and measure whether those changes are working
Bring your questions. We’ll reserve time at the end for Q&A.
