Overview
SignalFx built a cloud-native monitoring and observability platform using streaming analytics to track infrastructure and application metrics at scale. Founded in San Mateo, the company targeted modern SaaS and microservices architectures with real-time alerting and dashboards. Andreessen Horowitz led an $8.5M seed in 2013; CRV led a $20M Series B in 2015. Splunk acquired SignalFx in 2019 for approximately $1.05B to expand its observability cloud capabilities.
