Less than a year after emerging from stealth $5 million in seed funding, HD Moore’s Rumble asset management startup is attracting heavy interest from venture capital investors.
The Austin, Texas-based Rumble on Monday announced it had banked a new $15 million in Series A financing from Decibel Partners and a laundry-list of boldface cybersecurity practitioners.
Rumble, created by HD Moore (of Metasploit fame), sells technology to help defenders monitor exposed attack surfaces. The company said the new money will help accelerate go-to-market and engineering initiatives.
Since closing its seed round last March, Rumble claims it has quadrupled its customer base in a growth spurt that saw ARR increase five-fold in 2021.
The company said it has expanded its scanning, fingerprinting, reporting, and integration capabilities over the last year. The Rumble platform is now capable of identifying machines with wireless adapters and endpoint agents, over the network, without authentication, the company said.
Rumble officially launched in October 2019, after a six-month beta period. The platform was designed to inventory IT and OT environments to help with attack surface reduction and incident response.
