The company was founded 2009 in Toronto, Ontario, by
University of Waterloo graduates Alex Solomon, Andrew Miklas, and Baskar Puvanathasan. The company was incubated at
Y Combinator. In July 2016, the former CEO of
Keynote Systems, Jennifer Tejada, was named
CEO of PagerDuty. In June 2018, PagerDuty launched Event Intelligence, a product designed to analyze incoming digital signals and human responses to communicate incident response suggestions to operators when new incidents occur. At its industry conference in September 2018, the company also launched PagerDuty Visibility and PagerDuty Analytics. In March 2019, PagerDuty filed its S-1 with the SEC in anticipation of its
IPO and in April 2019, PagerDuty went public on the
New York Stock Exchange. On January 21, 2023 PagerDuty CEO Tejada's layoff memo was criticized for insensitivity for inappropriately quoting Martin Luther King, announcing promotions of executives, and tone deafness. In July 2025, the company began looking for buyer interest and exploring the idea of selling. == Funding ==
