PagerDuty, the San Francisco-based AI-first operations management platform, has appointed John DiLullo as Chief Executive Officer effective May 11, 2026, succeeding Jennifer Tejada, who has served as CEO since 2016 and will transition to Executive Chair of the Board of Directors.
The appointment follows a succession-planning process led by Tejada and the Board, with Tejada expected to work closely with DiLullo to support a seamless leadership transition and the continued execution of the company’s long-term strategy.
DiLullo brings more than 25 years of experience leading enterprise software, cloud, and cybersecurity companies through periods of transformation and growth. He most recently served as CEO of Deepwatch, where he led a comprehensive operational transformation and repositioned the business for sustainable growth. Prior to that, he served as CEO of NASDAQ-listed LiveVox, which was ultimately acquired by NICE Ltd., and earlier as CEO of Lastline, an AI-based threat detection company acquired by VMware. He holds two U.S. patents and was a National Science Foundation Fellow at Stanford University.
Tejada’s nearly decade-long tenure saw PagerDuty scale more than tenfold, growing revenue from under $50 million to nearly $500 million and evolving from a startup into a profitable global category leader. The company today serves more than 35,000 customers and acts as essential infrastructure for more than half of the Fortune 500 and approximately two-thirds of the Fortune 100. Milestones under her leadership include the company’s IPO in 2019, international expansion across APAC, EMEA, Japan, and the U.S. public sector, and the evolution of PagerDuty into an enterprise-grade AI-first operations platform.
Alongside the leadership announcement, PagerDuty reaffirmed its outlook for the first quarter and full fiscal year 2027, expecting first-quarter total revenue of $118 million to $120 million and full-year total revenue of $488.5 million to $496.5 million. The company expects to report first-quarter fiscal year 2027 results on May 28, 2026. PagerDuty’s Operations Cloud platform ingests signals from over 700 integrations to orchestrate responses across people, machines, and software for mission-critical digital operations.
