Sentrial

Sentrial is a Y Combinator-backed company that datadog for Agent Reliability. The company participated in the Winter 2026 batch of Y Combinator.

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.

Sentrial was part of Y Combinator's Winter 2026 cohort, has a team of approximately 2 employees, and is actively operating.
