They then co-founded Splunk Inc in 2003 with venture firms August Capital and JK&B Capital providing the required funding. Splunk emerged as product software for searching, monitoring, and analyzing the machine generated big data through a web style interface.

The Splunk as software product captures indexes and correlates the available data in a data bank from which it can generate graphs, reports, alerts, dashboards and visualizations. The corporate office of Splunk is located in San Francisco with regional offices located across Europe, Middle East, Africa and Asia. Splunk as of now has emerged as a consumer of any sort of machine data from logs to twitter feeds to network traffic.
