The AI SRE that catches production issues before you get paged
Herald builds a context graph across observability, codebase, CI/CD, docs, and dependencies before alerts fire, so it understands what normal looks like.
No thresholds to tune: Herald builds a custom anomaly detection model for each data stream and surfaces validated issues before customers notice.
The agent evaluates multiple hypotheses at once against the right data sources and delivers root-cause analyses in minutes without runbooks.
100% RCA accuracy on known issues and 70%+ on novel incidents, learning from every investigation so it never repeats a mistake.

An AI production engineer that watches every deploy and fixes issues before customers notice
Struct reads each pull request and generates the monitors and metrics needed to verify that change in production, with no code changes required, then baselines alert thresholds automatically after deploy.
Every production alert is triaged automatically. Irrelevant ones are pruned, flappy ones are tuned as prod changes, and only real issues are escalated — each arriving with an owner, impact analysis and root cause.
When Struct is confident, it can open a fix PR on its own. You can also connect your own coding agent or software factory and let Struct dispatch and coordinate the remediation.
Struct accumulates context from your repositories, past incidents, alerts, fixes and team feedback, so guidance given once — such as never holding a database connection across a sleep — is remembered and applied to future PRs.
