Rumble Raises $5M in Funding


Rumble, an Austin, Texas-based global network and asset discovery company, raised $5m in venture capital funding.

The round was led by Jon Sakoda and Dan Nguyen-Huu at Decibel Partners, with participation from Jon Oberheide (co-founder and CTO, Duo Security), Slavik Markovich and Rishi Bhargava (founders of Demisto, acquired by Palo Alto Networks), Oliver Friedrichs (founder & CEO of Phantom Cyber, acquired by Splunk), Haroon Meer (founder of Thinkst Canary) and Michael Sutton (founder at StoneMill Ventures).

The company intends to use the funds to develop the product’s enterprise capabilities and broaden its go-to-market reach.

Led by HD Moore, co-founder and chief executive officer, Rumble is an accurate network and asset discovery platform that inventories IT and OT environments. The Rumble Explorer scanner does not require credentials, agents, or SPAN ports to provide accurate fingerprinting, and helps security teams identify risks such as outdated and orphaned devices, rogue RDP ports, and public-private network bridges. Rumble identifies both managed and unmanaged devices on the network with a high degree of accuracy.
