Prometheus is the CNCF-graduated metrics and monitoring system used in production at SoundCloud (where it was built), DigitalOcean, Shopify, and most Kubernetes deployments worldwide.

Prometheus is a time-series metrics system released in 2012 at SoundCloud and donated to the CNCF in 2016, where it became the second project to graduate (after Kubernetes). It is Apache 2.0 licensed. The design is pull-based: Prometheus scrapes HTTP endpoints on target services, stores samples in a local TSDB, and exposes PromQL, a query language built around labels and vector operations.
Its integration with Kubernetes is what cemented its position—the service discovery model maps directly onto Kubernetes pods and services, and most Kubernetes monitoring out of the box assumes a Prometheus-compatible endpoint. For long-term storage and horizontal scaling, teams pair it with Thanos, Cortex, Mimir, or VictoriaMetrics. Alertmanager, developed alongside, handles routing and deduplication.
Prometheus is used at SoundCloud (where it originated), DigitalOcean, Shopify, Robinhood, GitLab, Uber, and essentially every team running Kubernetes at non-trivial scale. It is the default metrics stack inside most CNCF projects, most cloud-native SaaS companies, and the CNCF itself. Managed Prometheus services ship on AWS, GCP, and Azure.
Prometheus users are SREs who instrument infrastructure, platform engineers who run the scrape targets, backend engineers who add application metrics via client libraries, and on-call engineers who write PromQL alerts. These personas buy dashboards (Grafana), log aggregators, APM, incident management, and long-term metric storage.
According to the Prometheus README: “Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system.” (source)
If you sell a tool that integrates with Prometheus, complements it, or competes with it, the developers contributing to it are your buyers. They're the ones evaluating tools in your category right now.
Developers signal interest through GitHub activity—starring, forking, opening issues, submitting pull requests. LeadCognition captures those signals across millions of repositories and enriches each developer with verified work email, LinkedIn URL, and current employer.

Prometheus is used in production at SoundCloud (creator), CoreOS, Kubernetes (built-in metrics), and virtually every company running a modern observability stack — Prometheus is the de-facto metrics standard.
Prometheus is a CNCF graduated project, originally created at SoundCloud and donated to the CNCF in 2016. Governed by a core team and Prometheus development team, with major contributions from Grafana Labs and many companies.
InfluxDB (metrics + time-series, TICK stack), Datadog (hosted metrics + APM), Graphite (older, Carbon-based), VictoriaMetrics (high-performance, Prometheus-compatible drop-in), and OpenTelemetry Metrics (the new collection standard feeding Prometheus).
Prometheus has 1,369 contributors (GitHub, 2026/04). It is one of the more actively contributed open-source projects in its category, with contributions from both individual developers and corporate engineering teams.
