On July 17, 2025, IRIS Software Group announced Jason Dies as its new Chief Executive Officer, effective July 14, 2025, succeeding Gus Malezis, who will continue as Chairman of the Board. Dies, based in Connecticut, brings over 30 years of leadership experience, most recently as Interim CEO of Pitney Bowes, a $3 billion technology and logistics firm serving 90% of the Fortune 500. Gus Malezis stated: “Jason has a proven track record of driving customer-centric performance at scale, achieving ambitious financial and operational goals, and transforming organisations through innovation.”
Dies aims to accelerate IRIS’s innovation and global expansion, leveraging its reputation as a trusted partner for over 100,000 customers in 135 countries. He stated: “I’m looking forward to working with this talented team to build on that commitment to clients, to accelerate innovation, strengthen our technology roadmap, and continue delivering meaningful value for our customers.” With 20 years at IBM in roles across services, hardware, and marketing, and nearly a decade at Pitney Bowes, Dies has led global teams across North America, Europe, and Asia, driving transformation and operational efficiency.
IRIS, founded in 1978, reported $750M in revenue and employs 2,900 people across six continents as of July 2025. The 2024 acquisition of Dext, valued at ~$4 billion, increased revenues by 20%. Backed by Hg, Leonard Green & Partners, and Intermediate Capital Group, IRIS secured $50M in funding to support its cloud-based HR, payroll, and accounting solutions, used by nearly five million employees globally. The global HR and payroll software market is projected to reach $47 billion by 2030, positioning IRIS for growth amid competition from Workday and SAP.
IRIS has bolstered its leadership team, with recent U.S.-based appointments including Jairam Padmanabhan (VP, Head of Product), Shanna Milford (Senior HR Director), and Jack Sebbag (Chief Revenue Officer). Dave Burns was named Chief Customer Officer in January 2025, emphasizing customer success. These moves align with IRIS’s focus on North American expansion, where one-third of its revenue is generated. Posts on X reflect positive sentiment, with @HRTechSeries noting Dies’s appointment as a step toward global growth.
