When bombs went off at the Boston Marathon in 2013, the city used Everbridge to reach police, firefighters, hospitals and residents during the lockdown that followed. A year earlier the system sent more than 10 million messages to people in the path of Hurricane Sandy. Everbridge sold software for mass alerts. It reached people by phone, text and email, and stopped once they had read the message. In 2015 it sent 1.1 billion communications.

Born After September 11

Cinta Putra, Steve Kirchmeier, Patrick Stuver and James Keene started the company in 2002, after the September 11 attacks showed how hard it was to coordinate a crisis. It began as 3n Global. In 2008 it merged with National Notification Network, and in April 2009 it took the name Everbridge. The bet was that every city, hospital and large company needed one system to warn people and to hear back whether they were safe.

From Nasdaq to Thoma Bravo

Everbridge sold shares at $12 in September 2016, raising $90 million, and listed on Nasdaq as EVBG. Revenue grew from $104 million in 2017 to $271 million three years later, and use rose during the COVID-19 pandemic. It bought a string of companies, including Nixle and xMatters. Thoma Bravo agreed to buy Everbridge in 2024, raising its bid to about $1.8 billion after a rival offer. The deal closed in July 2024.
