PagerDuty, the leader in AI-first operations management, announced that John DiLullo has been appointed Chief Executive Officer, effective May 11, 2026. DiLullo succeeds Jennifer Tejada, who has served as CEO since 2016 and has transitioned to Executive Chair of the Board of Directors. DiLullo’s appointment follows a thoughtful and deliberate succession planning process, led by Tejada and the Board. Tejada will work closely with DiLullo to support a seamless leadership transition and continued execution of the Company’s long-term strategy.
DiLullo is a seasoned executive with more than 25 years of experience leading enterprise software, cloud and cybersecurity companies through periods of transformation and growth. He has a strong track record of driving operational discipline, scaling innovation, including AI-driven automation, and delivering profitable growth at critical inflection points. Most recently, he served as CEO of Deepwatch, where he led a comprehensive operational transformation and repositioned the business for sustainable growth. Previously, he served as CEO of the NASDAQ-listed LiveVox, and earlier Lastline, a venture-backed private company, leading both to successful outcomes.
Over nearly a decade of leadership, Tejada has overseen transformational growth including scaling PagerDuty more than tenfold, increasing revenue from under $50 million to nearly $500 million, and evolving PagerDuty from a startup into a profitable, global category leader in AI-first operations management. Today, the Company serves more than 35,000 customers and acts as essential infrastructure for more than half of the Fortune 500 and two-thirds of the Fortune 100. In her time as CEO and Chair of the Board, Tejada has played a vital role in shaping the industry, establishing PagerDuty as a category leader while bringing enterprise resilience and digital operations maturity to the C-suite and the boardroom. During her tenure, Tejada oversaw multiple major milestones, including the Company’s IPO in 2019, international expansion across APAC, EMEA, Japan and the U.S. public sector, and the continued evolution of PagerDuty from a single cloud application to an enterprise-grade AI-first operations platform and leading ecosystem, establishing a strong foundation for long-term profitable growth.

Together with our customers, including many of the world’s most important and innovative companies, we’ve built a platform that’s now essential to the world’s mission-critical operations, establishing our global leadership position. With retention stabilizing, new customer and expansion business accelerating, continued operating margin expansion and momentum in our AI-first Operations Cloud platform, I am confident this is the right time for this transition, and that John is the right leader to guide PagerDuty through its next phase of growth. In my role as Executive Chair, I look forward to partnering with John, our leadership team and the Board to continue building on our strong momentum.”
“I am honored to join PagerDuty at such an exciting time in the Company’s journey,” said DiLullo. “I have long admired PagerDuty’s mission and critical role in digital operations as a customer and a partner and am excited by its growing strength in a world transformed by AI. I look forward to partnering closely with Jenn, the Board, the leadership team and our employees to further build on this momentum on a strong foundation, and lead the Company through its next phase of growth and innovation. We are entering a period where AI-enabled software development and increasingly complex digital environments will significantly expand the need for intelligent, real-time operations management. I believe PagerDuty sits at the center of this transformation and is exceptionally well positioned to capitalize on the opportunities ahead.”
