What Chronosphere, Inc. A Palo Alto Networks Company does

Chronosphere, Inc., founded in 2019 in New York City by former Uber engineers Martin Mao and Rob Skillington, builds a cloud-native observability platform purpose-built for Kubernetes and microservices-scale environments. The company's core technology originated from the M3 metrics database developed at Uber and now delivers metrics, logs, traces, and events collection with 99.99%+ proven reliability, scaling to hundreds of millions of data points per second and billions of active time series in single customer deployments. A modular architecture layers Control Plane (data optimization claiming 89% average data volume reduction), Chronosphere Lens (automated service discovery), Differential Diagnosis (queryless root cause analysis), Chronosphere SLOs, and AI-Guided Troubleshooting on top of the platform, with a separate Telemetry Pipeline built on Fluent Bit (acquired via Calyptia in January 2024, 13+ billion Docker pulls) handling log collection, transformation, and routing across cloud providers and SIEMs.

Chronosphere generates revenue through enterprise SaaS subscriptions priced on data volume, metrics cardinality, and team size, sold via direct field sales to large enterprises — including DoorDash, Zillow, Robinhood, Yahoo, Affirm, GM, Visa, and Abnormal Security — under annual contracts with usage-based components. The company achieved unicorn status in October 2021 with a $200M Series C led by General Atlantic and reached a $1.6B valuation after a $115M Series C extension in January 2023, raising approximately $343M in total from General Atlantic, GV, Greylock, Lux Capital, Addition, and Founders Fund. Consecutive Gartner Magic Quadrant Leader recognition in 2024 and 2025 validated its market position, culminating in Palo Alto Networks' January 29, 2026 acquisition of Chronosphere for approximately $3.35 billion and integration with the Cortex XSIAM and AgentiX platforms; co-founder Martin Mao joined Palo Alto Networks as SVP and GM of Observability.

Chronosphere, Inc. A Palo Alto Networks Company product offering

Product offering

Core offering

Chronosphere sells a cloud-native observability platform that ingests, optimizes, and analyzes metrics, logs, traces, and events from Kubernetes and microservices environments at hyperscale. Built on technology originated at Uber (M3) and centered on a single-tenant data store with 99.99% reliability, the platform combines a Control Plane for data reduction, AI-guided troubleshooting with transparent reasoning, and a Telemetry Pipeline built on Fluent Bit for log collection and routing. The offering targets enterprises running containerized workloads who need to control runaway telemetry costs while accelerating incident resolution.

Product overview

Chronosphere offers a unified observability platform plus modules architecture. The core Chronosphere Observability Platform provides metrics, logs, traces, and events collection with open source compatibility (Prometheus, OpenTelemetry), 99.99% reliability, and massive scalability. Built on this platform are key modules: Chronosphere Lens for automated service discovery and developer-centric troubleshooting; Differential Diagnosis (DDx) for queryless guided root cause analysis; Chronosphere SLOs for service level objective management; Control Plane for data optimization reducing volumes 89%; and Scalable Data Stores providing the underlying high-performance storage. The separate Chronosphere Telemetry Pipeline (built on Fluent Bit) handles log collection, transformation, and routing. AI-Guided Troubleshooting and Notebooks add intelligence and collaboration capabilities. Chronosphere Notebooks provide persistent workspaces alongside telemetry data for incident investigation. The portfolio enables customers to control costs, reduce incidents 75%, and accelerate troubleshooting.
