Honeycomb (legally Hound Technology, Inc.) is an observability platform built around high-cardinality, high-dimensionality event data rather than pre-aggregated metrics and dashboards. Founded in 2016 by Charity Majors and Christine Yen — former Parse/Facebook engineers who helped popularize the term "observability" in software engineering — Honeycomb lets teams query raw production events in real time via its BubbleUp anomaly-detection feature and a fast query builder, without predefining dashboards. The company is privately held, has raised roughly $150M including a 2023 $50M Series D led by Headline, and is widely used by SRE and platform-engineering teams alongside OpenTelemetry-instrumented services.
