Transformative technology to save lives.

RapidSOS: A project of CitySpark

While City Light Capital’s portfolio is limited to early stage companies with at least $1M in revenue, we bridge the gap between early stage innovation and venture equity investment through City Spark. This initiative allows our team and our network of mission-driven executives and entrepreneurs to advise and support select early stage companies that, like RapidSOS, demonstrate the potential to generate both high financial returns and social impact.

RapidSOS is an advanced emergency tech start-up commercializing technology to predict and preempt emergencies before they occur, warn people in harm's way, and connect any device directly to 911 and first responders in an emergency.


RapidSOS. Existing technology for 911 dates back to the 1960s. In the age of mobile phones, 911 dispatchers often cannot retrieve critical information such as caller location, and frequently inaccurately identify or locate callers.

RapidSOS’s Haven application uses existing GPS technology in mobile phones to accurately locate the origin of a 911 call to within a 3 meter radius. Users are also able to upload critical personal information into the app, such as medical history, medication allergies, and emergency contacts. This information allows first responders to more effectively treat injuries and alert loved ones.


Harnessing cutting edge technology to change the outcomes of millions of emergencies across the United States and globally.
