Requesting revisions to update following Splunk/Cisco purchases

I am a connected contributor with a declared COI. I am suggesting updates to this article since this is no longer an independent company following its integration into Splunk. I have used TextDiff templates and labeled each section. Thank you and I'm looking forward to any and all feedback.

'''SignalFx''' is a [[SaaS]]-based monitoring and [[analytics]] company headquartered in [[San Mateo, California]]. It offers capabilities for analyzing, visualizing, automating, and alerting on metrics data from infrastructure, applications, [[microservice]]s, [[Container (abstract data type)|containers]], and functions. The platform uses a streaming architecture that separates metric data into two streams: one for metadata and another for time-series values. These data streams are routed through a publish-subscribe ([[Publish–subscribe pattern|pub-sub)]] bus to SignalFlow, an analytics language accessible via the SignalFx [[GUI]] and programmable [[API]]s. The platform is designed to can process millions of data points per second millions of data points per second at a 1-second resolution, with latency typically under 2 seconds from ingestion to alerting.

Hi @Spintendo! Thank you for reviewing my request, and sorry for overlooking references for the removal of key people from the Infobox. Here are references that I hope will support correcting the Infobox.

Karthik Rau is now CEO of Contentful: https://www.axios.com/pro/media-deals/2024/10/31/contentful-ceo-karthik-rau

Mark Cranney was cited as “former SignalFX COO” in this 2020 article: https://venturebeat.com/technology/skydio-raises-100-million-announces-enterprise-focused-drone-lineup

Thanks again, and please let me know if you think anything else is needed to make these final corrections. SBCornelius (talk) 16:13, 27 May 2026 (UTC)

Hi @Spintendo! I hope all is well, and thanks for your recent input on other articles. I was wondering if you think the references I listed are sufficient to remove the CEO and COO from the Infobox? With a final decision on that, I'd consider all of my requests here wrapped up. Thanks and let me know if anything else is needed. SBCornelius (talk) 20:39, 7 July 2026 (UTC)

Hi @Spintendo, have you had a chance to consider the change to the key people parameter? Let me know if you think anything else is needed. Thanks! SBCornelius (talk) 18:49, 30 July 2026 (UTC)

Notes

Proposed edits to InfoBox

Hello! I am a connected contributor with a declared COI. The InfoBox for this article lists a CEO and a COO. However, SignalFX is no longer an independent company. It was acquired by Splunk and integrated into the Splunk Observability Cloud. For accuracy, the Key People section should be removed from the box. Below are two sources that support the fact that the executives listed no longer hold those positions.
