Monte Carlo: Building Data + AI Observability Agents with LangGraph and LangSmith

While Monte Carlo had built comprehensive troubleshooting tools, they identified an opportunity to further reduce this “data downtime:” have AI agents process and reason through hundreds of hypotheses concurrently to accelerate data + AI team’s ability to quickly spot and fix the root cause behind specific data quality incidents. With a tight 4-week deadline ahead of major industry summits, the team felt confident demonstrating their agent to customers— something that wouldn't have been possible with a custom-built solution.

How you could try it
