PagerDuty

Market position

Describes itself as a leader in digital and real-time operations management; the platform is used by roughly 30,000 organizations with over 1,000,000 users, and the company cites adoption by 68-70% of the Fortune 100. Its 2018 Series D made it a cloud unicorn at a $1.3 billion valuation, and it has been publicly traded since 2019.

The company emphasizes the breadth of its integration ecosystem, a large historical corpus of machine and human incident-response data used to train its machine learning and AI agents, full-lifecycle coverage from detection through post-incident review, bi-directional sync with existing systems of record, and the ability to coordinate business stakeholders and customer support rather than only technical responders.

Technology

Cloud-native SaaS platform that aggregates event signals from hundreds of third-party tools and applies machine learning to alert grouping and noise reduction, alongside on-call scheduling, escalation policies, dynamic routing, incident workflows and analytics. The company states its models are trained on 16 years of operational data covering more than 12 billion alert events, 952 million incident events and 15.9 million incident workflows per year, and it markets agentic AI components (SRE, Scribe, Shift and Insights agents) plus open APIs, an MCP server and Backstage support.

History

After its 2009 founding in Toronto and Y Combinator incubation, PagerDuty raised a $1.9 million seed round in 2010, a $10.7 million Series A in January 2013, a $27.2 million Series B in 2014, a $43.8 million Accel-led round in April 2017, and a $90 million Series D in September 2018 led by T. Rowe Price and Wellington Management that valued the company at $1.3 billion and brought total capital raised to $173 million. Jennifer Tejada, previously CEO of Keynote Systems, became CEO in July 2016. Product expansion included Event Intelligence in June 2018 and PagerDuty Visibility and Analytics in September 2018. The company filed its S-1 in March 2019 and listed on the New York Stock Exchange in April 2019. It expanded through acquisitions of Rundeck (October 2020), Catalytic (March 2022) and Jeli (November 2023). In January 2023 a layoff memo from the CEO drew public criticism, and in July 2025 Reuters reported the company was exploring a potential sale after receiving buyer interest.

Risks & controversies

In January 2023, CEO Jennifer Tejada's layoff memo was widely criticized for quoting Martin Luther King Jr., announcing executive promotions in the same message, and for its tone. In July 2025 the company was reported to be exploring a sale, which introduces strategic and ownership uncertainty. Several performance figures on the company's own site (e.g., 59% reduced disruptions, 27% more productive teams, 91% noise reduction) derive from vendor-commissioned studies and customer testimonials rather than independent verification.
