PagerDuty makes cloud-based software that helps companies detect and resolve incidents — outages, failures, and disruptions — in their technology infrastructure. When something breaks in a company's software or IT systems, PagerDuty detects the problem, filters noise, and routes the right alert to the right person or automated workflow to fix it quickly. PagerDuty's customers are enterprises that depend on always-on digital systems, including banks, retailers, telcos, and healthcare companies. Nearly half of the Fortune 500 are customers. PagerDuty sells primarily through a direct enterprise sales force for large accounts and a self-service motion for smaller customers, using a land-and-expand model where customers start small and grow usage over time. The core product is incident management — real-time alerting, on-call scheduling, and end-to-end incident response — which accounts for roughly 70% of ARR. PagerDuty also offers AIOps (machine learning-based event correlation and noise reduction), workflow automation, customer service operations tools, and a growing suite of generative AI agents for tasks like diagnosis, documentation, and scheduling. Revenue comes almost entirely from SaaS subscriptions. PagerDuty is transitioning from a seat-based pricing model to a hybrid model combining seat fees for core products and usage-based pricing for newer products like AIOps and AI agents — a shift driven by the fact that automation reduces headcount even as platform value grows. Gross margins run around 86-87%, and PagerDuty has expanded non-GAAP operating margins for six consecutive years, reaching approximately 24% in FY26.
