About Sentrial
Summary
Sentrial builds a monitoring and debugging platform for AI agents and products running in production. It detects failures such as infinite loops, hallucinations, and poor user experiences in real time, then diagnoses root causes and surfaces specific fixes. Engineering teams use it to replace guesswork from offline evaluations with direct visibility into how their AI behaves with live users.
Go-to-market
B2B teams shipping AI agents or AI-powered products are the buyers, adopting the platform to gain production observability that general-purpose monitoring tools do not provide.

Datadog for Agent Reliability
Sentrial is the monitoring platform for AI products in production. When your AI product/agent loops indefinitely, hallucinates, or frustrates users, Sentrial detects it in real-time, diagnoses the root cause, and recommends specific fixes. We provide the monitoring, evaluation, and debugging infrastructure that traditional tools weren't built for, so teams iterate based on production reality, not just offline evals.
