About ESNODE

ESNODE is a focused platform from Estimatedstocks AB that unifies high-frequency node telemetry, fleet control and optical fault localization. We help operators connect power, performance and reliability-across GPU clusters and fiber routes.

The ESNODE product line is built around a simple principle: keep components small, composable and vendor-neutral. We integrate with your existing observability stack instead of replacing it.

Founded and operated in Sweden. Privacy-first, standards-driven, enterprise-ready.
