SignalFx is a SaaS-based monitoring and analytics platform based in San Mateo, California which allows customers to analyze, visualize, automate, and alert on metrics data from infrastructure, applications, microservices, containers, and functions.[1][2] At the core of the platform is a streaming architecture that splits metric data points into two streams, one for human readable metadata and the other for time-series values. The data is routed through a pub-sub bus to SignalFlow, a python-like analytics language accessible through the main SignalFx GUI and through programmable API's. The platform is able to process millions of data points per second at a 1-second resolution with less than 2 seconds of latency, from ingestion to alert.[3][4]

## History

SignalFx was co-founded by Karthik Rau and Phillip Liu in February 2013.[5] Phillip Liu previously worked at Facebook for four years as a software architect and Karthik Rau worked at Delphix and VMware.[5][6] SignalFx received $8.5 million in a Series A investment from Andreessen Horowitz, adding Ben Horowitz to its board.[7] In 2015 Signal Fx received $20 million in Series B investment led by Charles River Ventures with participation from Andreessen Horowitz, adding Devdutt Yellurkar to its board.[8][9][5][10] In May 2018, SignalFx announced its Series D funding of $45 million led by General Catalyst with participation from the existing investors Andreessen Horowitz and Charles River Ventures. In June 2019, the company raised $75 million in its Series E round led by Tiger Global Management, bringing the companies total funding to $179 million since its founding.[11]

SignalFx currently serves over a hundred customers, including Athenahealth, Chairish, Ellie Mae, Carbonblack, Kayak, Shutterfly, Sunrun, and Yelp.[12][13]

On August 21, 2019, SignalFx was acquired by Splunk for $1 billion.[14]
