Our Mission


Software no longer just supports your business — it is your business. In a world of always-on, always-connected digital experiences, expectations for real-time, personalized engagement is the norm. Companies can no longer afford costly errors associated with bugs, inadequate capacity, and slow time to resolution.



Organizations of all sizes are embracing Cloud-Native technologies. But that’s just the beginning. They’re also applying automation and cognitive tools to solve problems much more quickly than humans can. It’s the only way to deal with massive data volumes that have outstripped the capabilities of traditional monitoring technology.

That’s why we created SignalFx — the only real-time cloud monitoring platform for infrastructure, microservices, and applications. With SignalFx, you can separate meaningful signals from mountains of noise, using automation to pinpoint and resolve issues before they affect customers. In real-time. At any scale.



The success of your business requires real-time analytics, operational intelligence, and automation. Staying ahead of your needs with the most complete solution is the single-minded mission of our entire organization. From the innovation champions on our leadership team to our frontline developer to our customer service professionals, SignalFx can help guide your company to a future that’s already here.



SignalFx was born in the earliest days of modern computing, when microservices architecture and container technology were just beginning to see early adoption. Being at the forefront of significant paradigm shifts is nothing new to our executive team.

Our founding engineers were some of the original developers of Facebook’s metrics-based monitoring solution (ODS) at a time when Facebook grew its membership exponentially and drove numerous product innovations. They subsequently managed the development of its networking tools, data visualization, and other infrastructure monitoring software — effectively creating one of the industry’s first DevOps monitoring platforms well before the idea of DevOps was widely embraced or understood.

Likewise, from LoudCloud and Opsware, to Red Hat and VMWare, to PTC and Sprinklr, our executives have led technology developments that, even now, continue to advance the Cloud-Native journey.
