Visit websiteWhat is Sentrial?
Sentrial is a production monitoring platform purpose-built for AI agents — positioned as "Datadog for Agent Reliability." Part of YC W2026, it was founded by Neel Sharma (CEO, UC Berkeley CS, ex-Sense) and Anay Shukla (UC Berkeley CS, deployed DevOps agents at Accenture).
The platform semantically detects when agents loop, hallucinate, misuse tools, or frustrate users in production, then helps engineering teams diagnose the root cause and fix it fast. Integration requires just a few lines of code via SDK or MCP. Sentrial learns what "correct" looks like for each workflow and flags drift from expected behavior.
The founders built Sentrial after encountering real production failures: a support agent misclassifying refund requests as product questions, and a document drafting agent hallucinating missing sections. Traditional observability tools track latency and errors but cannot semantically evaluate whether an agent's output is actually correct — Sentrial fills this gap with AI-native monitoring.
Key Features
- ✓Agent failure root cause analysis
- ✓Tool selection monitoring
- ✓Cost budget tracking
- ✓Production agent observability
- ✓Real-time alerting
Pros & Cons
Pros
- +Addresses genuine growing pain point as agents move into production
- +Semantic detection of loops, hallucinations, and tool misuse goes beyond basic logging
- +Low-friction integration with just a few lines of code via SDK or MCP
- +Proven Datadog-for-X positioning in enterprise software
- +Founders have relevant agent deployment experience at Sense and Accenture
Cons
- -No disclosed customers, revenue, or traction metrics
- -Early feedback flagged website bugs — ironic for a reliability company
- -Defining wrong agent behavior universally is technically very challenging
- -Incumbents like Datadog and LangSmith are adding agent observability features
