Circonus

Founded in 2010 by Theo Schlossnagle, Circonus operates as a data analytics company providing a platform for real-time IT infrastructure monitoring. Schlossnagle, a computer scientist with degrees from Johns Hopkins University and a background in distributed systems, established the company to address complex scalability and performance challenges. His expertise in scalable internet architectures and distributed systems directly shaped the core functionalities of the Circonus platform. The company has secured $16.8 million in funding over three rounds, with its latest Series B funding in November 2021 raising $10 million, led by Baird Capital. In a significant milestone, Circonus was acquired by Apica, a firm specializing in data management and active observability, on February 20, 2024.

The core of Circonus's business is its unified monitoring and analytics platform, which caters to enterprises requiring real-time visibility into their IT environments, from traditional infrastructure to cloud-based technologies. The platform is designed to ingest, store, and analyze vast quantities of telemetry data—billions of metric streams—from any application or system. This capability allows clients to monitor health, trends, and performance across their entire technology footprint. Circonus serves a range of clients, including notable names like EA Sports, Redfin, HBO, and Major League Baseball, helping them optimize operations and deliver mission-critical services. Revenue is generated through a subscription-based model, with pricing starting from a monthly fee.

Circonus's product suite offers a powerful, consolidated view that reduces troubleshooting time by unifying various monitoring, alerting, and analytical tools. A key feature is its proprietary time-series database, IRONdb, which is designed for high cardinality and can handle over a billion unique metric streams. The platform also includes the Circonus Unified Agent (CUA), which can collect telemetry data from over 300 different technologies, including VMware's vSphere and Oracle's DBMS. It provides advanced predictive analytics, including anomaly detection, capacity planning, and dynamic alerts. The system integrates with various communication and on-call management tools to deliver timely notifications. Following the acquisition by Apica, Circonus's IRONdb and Passport products are being integrated into the Apica Ascent platform to enhance its observability data management capabilities.
