Overview
Everbridge is an American enterprise software company whose technology is designed to help governments, emergency services, infrastructure operators, businesses, and other organizations communicate during critical events. Its systems distribute time-sensitive information through channels such as telephone calls, text messages, email, mobile applications, and other connected communication systems. A central feature of the platform is the ability to target messages to particular populations or locations and to track whether recipients have received or read them, allowing operators to follow up when communication has not been completed. The company began operations in 2002 under the name 3n Global, a wholly owned subsidiary of the National Notification Network. Its creation was associated with the need for improved crisis coordination following the September 11 attacks. The business adopted the Everbridge name in April 2009. Over time, it expanded from notification services into a broader critical-event management platform incorporating threat intelligence, social-media information, traffic-camera data, 9-1-1 data, location information, and operational workflows. Everbridge became known through deployments in both public-sector and commercial settings. During Hurricane Sandy in 2012, its system was used to send more than 10 million messages to residents. Following the Boston Marathon bombings in April 2013, Boston used the platform to communicate with business operators, employees, firefighters, hospital personnel, police, and residents during the emergency and subsequent lockdowns in Boston, Watertown, Waltham, and nearby areas. The technology was also used for emergency communications during hurricanes, including Hurricane Dorian, and for public updates during the COVID-19 pandemic. These deployments helped position the company as a provider of large-scale, multi-channel communications rather than merely a conventional mass-notification vendor. The company broadened its product and geographic capabilities through acquisitions. Businesses and technologies added to the portfolio included Nixle, IDV Solutions, Svensk Krisledning, Unified Messaging Systems, NC4, one2many, Techwan, SnapComms, xMatters, RedSky Technologies, and Anvil. These transactions extended Everbridge into public-safety notifications, incident management, visual intelligence, mobile alerting, unified communications, employee safety, IT incident response, and related operational workflows. Everbridge completed an initial public offering in 2016 and traded on Nasdaq under the symbol EVBG. Its reported revenue grew from $104 million in 2017 to $271 million in 2020, reflecting increased adoption of critical-event and continuity tools. In March 2024, Thoma Bravo agreed to acquire the company for approximately $1.8 billion after Everbridge received a superior proposal during a go-shop period. The transaction closed in July 2024, taking Everbridge private and ending its public-market listing. The company continues to serve public agencies, emergency managers, enterprises, transportation organizations, healthcare institutions, and other customers that require coordinated communication during disruptions.
History
Everbridge originated in the United States in 2002 as 3n Global, a wholly owned subsidiary of the National Notification Network. Its formation followed the September 11 attacks and reflected a demand for systems that could coordinate crisis communications among public authorities, businesses, employees, and other affected groups. The early business focused on notification: sending urgent messages through telephone, text, and email and helping operators identify whether recipients had received or read them. The company adopted the Everbridge name in April 2009. Under that identity, it developed from a notification provider into a broader critical-event management business. Its systems combined communication channels with information from threat-data feeds, social media, traffic cameras, 9-1-1 systems, and location-aware technologies. These capabilities allowed customers to identify an incident, assess its likely impact, target particular populations, send instructions, and monitor response as conditions changed. Large emergency deployments increased the company's visibility. During Hurricane Sandy in 2012, Everbridge was used to deliver more than 10 million messages to residents. In April 2013, Boston used the platform after the Boston Marathon bombings to communicate with business operators, employees, firefighters, hospital staff, police, residents, and other stakeholders. Everbridge was involved in communications during the resulting lockdowns affecting Boston, Watertown, Waltham, and surrounding areas. The platform was later used in other severe-weather situations, including Hurricane Dorian, and during the COVID-19 pandemic, when public agencies and organizations needed to issue frequent updates and coordinate changing operating procedures. Everbridge expanded through a sequence of acquisitions. Nixle, acquired in 2015, strengthened public-safety and community notification. IDV Solutions and Svensk Krisledning were acquired in 2017, followed by Unified Messaging Systems in 2018 and NC4 in 2019. In 2020 the company acquired one2many, Techwan, and SnapComms. The 2021 acquisitions of xMatters and RedSky Technologies broadened its incident-management, employee-safety, and communications capabilities, while Anvil was acquired in 2022. Together, these additions supported a more extensive platform spanning emergency alerts, operational response, workplace communications, IT incident management, and situational awareness. Everbridge became a public company in 2016 through a Nasdaq initial public offering that raised $90 million. Its reported revenue increased from $104 million in 2017 to $271 million in 2020. Customers identified in reference material include the University of Mississippi, the United States Army, the state of West Virginia, Hartsfield-Jackson Atlanta International Airport, and the governments of Norway, Peru, and Australia. In 2024, private-equity firm Thoma Bravo agreed to purchase Everbridge. The offer was increased to approximately $1.8 billion after Everbridge reported receiving a superior proposal during the 25-day go-shop period. The transaction closed in July 2024, and Everbridge became privately held. Its continuing business is centered on software for critical-event communications, public safety, employee safety, business continuity, and incident response.
