Production monitoring platform for AI agent reliability

Sentrial is a YC W26-backed monitoring platform for AI agent reliability in production. It semantically detects loops, hallucinations, tool misuse, and user frustration in real-time, then diagnoses root causes and recommends fixes. The platform claims 70% MTTR reduction via automated remediation including rollback, model retraining triggers, and webhooks. Sentrial positions itself as the Datadog for teams deploying autonomous AI agents at scale.

AI production engineer that auto-triages and fixes alerts

Sonarly is a YC W26-backed AI production engineer that autonomously triages production alerts, deduplicates them by root cause, and sends ready-to-merge pull request fixes. It connects to monitoring tools like Sentry and Datadog, analyzes alert patterns to identify the underlying issue, and generates code fixes or optimization recommendations. Built on Claude APIs, Sonarly reduces mean time to resolution for production incidents while minimizing alert fatigue for engineering teams.
