Company profile
researched Aug 2026RapidSOS operates an emergency response data and AI platform that links connected devices, apps, sensors and cameras to 911 centers, public safety agencies and first responders. The company describes its network as connecting public safety, enterprises and consumer and corporate devices, so that context such as caller location, telematics and crash data, health profiles, hazmat information and live video reaches telecommunicators and field crews before or during a response. Its stated coverage spans agencies and enterprises safeguarding over 99% of the United States, with reported use across roughly a dozen countries covering nearly 700 million people.
Product lines documented include RapidSOS Connect (an emergency API), RapidSOS Portal (a free tool giving 911 telecommunicators vetted data from connected devices), RapidSOS Premium (Portal plus additional mapping and workflow capabilities), RapidSOS Safety (AI-enabled safety agent support), and RapidSOS Integrations (allowing GovTech and public safety software vendors to embed platform data). RapidSOS HARMONY is described as a purpose-built AI for public safety that automatically detects emergencies, unifies real-time data and video streams, and coordinates response. Vertical offerings target 911 agencies, law enforcement, fire/EMS, enterprises, healthcare, schools, state governments and consumers.
The company's first product was Haven, a smartphone application that let users share real-time family location, check in, and call 911 on behalf of another person while transmitting that person's location and personal details to the nearest dispatch center. RapidSOS subsequently shifted to sending emergency data to 911 telecommunicators without requiring users to run a dedicated app.
Founding story
Founder Michael Martin has cited two personal experiences behind the company: his father fell from the roof of his home in Rockport, Indiana, breaking his wrist and shattering his hip, and could not reach 911 from his cellphone, remaining outside in freezing temperatures until his wife returned home and called from a landline; and, after moving to New York City, Martin was followed by a man intending to rob him and found how difficult it is during an emergency to take out a phone, dial and hold a coherent conversation about identity, location and what is happening. He co-founded RapidSOS with Nicholas Horelik to close that 911 data gap.
Business model
RapidSOS sits between device makers, apps and enterprises on one side and public safety agencies on the other. Public safety-facing tools such as RapidSOS Portal are offered free to 911 telecommunicators, with Premium adding mapping and workflow capabilities, while technology companies, enterprises and software partners connect to the network through APIs and integrations. The company reports 200+ global enterprise partners, including half of the US Fortune 10, and 5,800+ public safety and defense software integrations.
Traction
As of November 2025 the company reported crossing one billion emergencies supported, 600 million+ connected devices, apps, sensors and cameras, 22,000+ public safety and defense agencies, 200+ enterprise partners, 1 million+ first responder users and 5,800+ public safety/defense software integrations. Wikipedia cites 600 million devices connected to 15,000+ first responder agencies.
Latest developments
On November 19, 2025, RapidSOS announced a $100 million financing round led by the Apax Digital Funds, bringing total capital raised to over $450 million, alongside crossing one billion emergencies supported. Proceeds are earmarked for scaling the safety network, deepening interoperability across 911 and field-response workflows, advancing AI tools for triaging and resolving emergencies, and international expansion with governments and global technology providers; the company stated an aim to prevent one million emergencies by 2030. Recent activity highlighted on its site includes Innovation Day 2026 content, a case study on Atlanta's 911 center scaling World Cup event response, and use of Harmony AI by a major metro police department for multilingual emergencies.

Market position
RapidSOS describes its network as the world's largest safety network, used by agencies and enterprises safeguarding more than 99% of the United States, with 22,000+ federal, state, local and defense agencies, 200+ global enterprises including half of the US Fortune 10, and more than 1 million first responder users globally. Apax Digital characterized the company's data infrastructure as underpinning much of modern safety, security and disaster response and as powering emergency management in agencies across about a dozen countries covering nearly 700 million people.
RapidSOS emphasizes an interoperable network built in collaboration with public safety, combining a broad device and enterprise data layer with AI (HARMONY) to deliver pre-arrival intelligence before responders reach the scene, and integrations with thousands of public safety software systems rather than a standalone consumer app.
Technology
The platform aggregates data from over 600 million connected devices, apps, sensors and integrated cameras and routes it to emergency call takers and responders, covering real-time caller location, vehicle crash and telematics data, health profiles, hazmat details and live video. RapidSOS HARMONY is described as purpose-built AI for public safety that automatically detects emergencies, unifies real-time data and video streams and coordinates response, and is also used for handling multilingual emergency calls. RapidSOS-enabled crash detection has been credited with a dispatch 13 seconds after a crash was detected in rural Michigan.
Go-to-market
The company markets through direct sales and demo requests to 911 agencies, law enforcement, fire/EMS, healthcare, schools, state governments and enterprises, and grows the network through partnerships with large technology and consumer companies including Apple, Google, Axon, Uber, SimpliSafe, Cove, SiriusXM, MedicAlert and Grubhub. It also runs customer-facing content and events such as Innovation Day, READY virtual events, video testimonials and documentary storytelling, plus an email newsletter.
Federal, state, local and defense public safety agencies and 911 centers; law enforcement, fire and EMS; enterprises and technology companies; healthcare providers and medical device makers; schools; state governments; and consumers via connected phones, vehicles and devices.
Geography
Headquartered in New York, United States, with coverage of agencies and enterprises safeguarding over 99% of the US and emergency management deployments in about a dozen countries covering nearly 700 million people; the company states plans for further international expansion.
History
Per Wikipedia, RapidSOS was founded in 2012 by Michael Martin and Nicholas Horelik to address the 911 data problem, launching with the Haven smartphone app. The company studied data from more than 12 million 911 calls between 2012 and 2015, then tested its platform with location data alongside Emergency Communication Centers from 2016 to 2017. In 2018 it worked with Apple so that U.S. iPhone users calling 911 could automatically share location data with first responders through the RapidSOS platform, and later that year partnered with Google to route Android ELS data through the platform. It added product lines including RapidSOS Safety, Portal, Premium and Integrations, and in March 2023 announced a partnership with Grubhub to share dynamic location data and caller ID with 911 when drivers call for help from the Grubhub for Drivers app. In November 2025 the company announced a $100 million financing round led by the Apax Digital Funds, bringing total capital raised to over $450 million.
