Chronosphere is a remote-first software company with major hubs in New York City and Seattle that provides a cloud-native observability platform for engineering teams to monitor and troubleshoot complex infrastructure. Founded in 2019 by former Uber engineers Martin Mao and Rob Skillington, the enterprise SaaS business supports massive volumes of metrics data, scaling to billions of active time series for artificial intelligence and digital-native workloads. Operating with a workforce of more than 250 employees, the organization has generated over $160 million in annual recurring revenue. Prior to agreeing to a $3,350,000,000 acquisition by Palo Alto Networks in 2025, the company raised $343 million in total funding and reached a $1,600,000,000 valuation. Its venture capital backers include prominent investment firms such as Greylock Partners, General Atlantic, Lux Capital, Spark Capital, Addition, and Founders Fund.

Chronosphere is a cloud-native observability platform designed primarily for DevOps and site reliability engineering teams managing complex, containerized, and microservices-based environments. It helps organizations reduce the cognitive load of monitoring by consolidating infrastructure, application, and business health data into a single control plane. Chronosphere enables companies to control skyrocketing observability data volumes and costs while accelerating issue detection and resolution, thereby improving developer productivity and customer satisfaction. Its platform serves large enterprises and high-scale digital businesses such as DoorDash, Snap, Zillow, and Uber, addressing the challenges of operating reliable systems at scale in the cloud-native era[1][3][4].
Chronosphere was founded in 2019 by Martin Mao and Rob Skillington, both with backgrounds in engineering and software development. The idea originated from their experience at Uber, where early adoption of cloud-native architecture revealed a lack of suitable monitoring tools capable of handling the scale and complexity of modern infrastructure. Uber’s internal solution for observability, launched in 2017, was highly successful in preventing outages and providing real-time business insights. Recognizing the broader market need, Mao and Skillington created Chronosphere to commercialize this technology and serve other enterprises facing similar challenges[1][6].
Chronosphere rides the wave of cloud-native transformation, where enterprises increasingly adopt microservices, containers, and Kubernetes to build scalable, resilient applications. This shift generates massive volumes of observability data, creating complexity and cost challenges that legacy tools cannot address effectively. Chronosphere’s timing is critical as organizations seek to harness observability as a competitive advantage to maintain uptime, optimize costs, and accelerate innovation. By enabling better control over observability data and costs, Chronosphere influences the broader ecosystem by setting new standards for scalable, cost-efficient monitoring in cloud-native environments[1][3][4].
Looking ahead, Chronosphere is positioned to deepen its impact by expanding its platform capabilities, as evidenced by recent strategic moves like partnerships with CrowdStrike and acquisitions such as Calyptia. Trends shaping its journey include the continued growth of cloud-native adoption, increasing complexity of distributed systems, and the rising importance of observability in business decision-making. Chronosphere’s influence is likely to grow as it helps enterprises not only maintain operational excellence but also leverage observability data as a strategic asset, reinforcing its mission to guide modern businesses toward competitive advantage through observability[3].
Chronosphere has raised $344.0M across 4 funding rounds. Most recently, it raised $120.0M Series C in January 2023.
