RapidSOS announced it closed a $75 million financing round, bringing total capital raised to over $250 million. 

Leading this latest round of funding is NightDragon, headed by veteran cybersecurity and tech executive Dave DeWalt, who will additionally join RapidSOS' Board. DeWalt previously served as CEO of three public companies including McAfee and FireEye and is the founder of NightDragon. NightDragon invests in late stage, high-growth cybersecurity, safety, security and privacy companies. 

The funding comes as RapidSOS has supported the greatest volume of emergencies in its 10-year history, with aging populations, increasing crime, severe weather and the on-going implications of the global pandemic, according to the announcement. So far in 2022 the company has supported first responders in managing over 130 million emergencies. 

Built over the past decade in partnership with first responders, RapidSOS provides turn-key professional monitoring, voice and data connectivity for over 90 tech companies, more than 50 public safety software vendors, and over 15,000 first responder agencies on four continents. 

"For a decade, we've had the privilege to learn from our nation's first responders to build technology that supports their life-saving work," said Michael Martin, Founder and CEO of RapidSOS. "Hundreds of millions of lives are impacted each year by the heroism of these individuals, and we're honored to have partners in this journey that share in a vision to transform safety, security, and emergency response." 

This most recent raise additionally includes investments from BAM Elevate, Insight Partners, Honeywell, M12 Microsoft's Venture Fund, Axon, Citi via the Citi Impact Fund, Highland Capital Partners, Playground Global, Forte Ventures, C5 Capital, and Avanta Ventures.
