Dallas, Texas, October 12, 2026: Mastek, a trusted AI-first digital engineering and cloud transformation partner and CORT Business Services, a Berkshire Hathaway company, have won the 2026 ISG Paragon Partnership of the Year award for North America, recognizing their decade-long partnership and continued evolution in digital and business transformation. For more than 10 years, Mastek has partnered with CORT to evolve CORT’s digital and technology landscape across B2C, B2B and international markets. What began as application modernization and digital commerce transformation has progressively evolved into a strategic partnership spanning digital engineering, platform modernization, AI-led transformation and consolidated managed services. Together, Mastek and CORT have modernized digital commerce, strengthened customer experience and enabled new business capabilities across B2C, B2B and international markets. Mastek supports CORT’s digital ecosystem through application modernization, digital engineering, quality engineering, cloud and managed services, helping create a foundation for continuous innovation and business growth. More recently, Mastek designed, built and launched CORT Furniture Outlet, a business-to- consumer eCommerce platform that enables customers to discover and purchase high-quality used furniture online or in-store at discounted prices. Within two weeks of launch, the platform delivered a 37% increase in online conversion rates, a 69% increase in overall online purchase volume and a 30% increase in organic traffic. Mastek’s managed services team has continued to support and enhance the platform following its launch. Building on this foundation, the partnership is now advancing toward an AI-led business transformation roadmap, focused on embedding AI across customer journeys, digital commerce, engineering and operations to accelerate decision-making, automate processes and create new sources of business value. The roadmap also explores the evolution of traditional managed services toward a “Services as Software” model, combining AI, automation, reusable digital capabilities and outcome-based services to deliver technology and business capabilities with greater speed, scale and intelligence. This next phase reflects a broader shift from technology modernization to continuous, AI- powered business transformation—where digital platforms, data, AI and services work together to help businesses respond faster to changing customer expectations and continuously create measurable value. The ISG Paragon Awards recognize innovative technology and sourcing partnerships that drive business and IT transformation. Mastek and CORT accepted the award at the ISG Paragon Awards North America 2026 ceremony on September 24, 2026. “Great partnerships are built on trust, strong leadership and a shared commitment to business outcomes. Our decade-long relationship with CORT reflects the strength of that collaboration and what we can achieve together. As we look ahead, we are excited to build on this foundation through AI-led transformation, intelligent automation and new ways of delivering technology and business value,” said Sourabh Mukherjee, President of Americas, Mastek. “Mastek has been a true strategic partner to CORT, bringing a deep understanding of our business, a willingness to challenge the status quo and a consistent focus on delivering results. Over the past decade, our teams have worked side by side to navigate complex technology and business challenges, modernize our digital capabilities and create better experiences for our customers. As our business and customers continue to evolve, our partnership with Mastek is also evolving, with AI and new digital capabilities creating opportunities to accelerate innovation and deliver even greater value,” said Dennis Crawford, VP of Product Development, CORT. “For us, the true measure of digital transformation is the business outcome it creates. Our decade-long partnership with CORT demonstrates what can be achieved when deep industry understanding, technology expertise and a shared commitment to outcomes come together. We have continuously evolved our partnership—from modernization and digital commerce to managed services and now toward AI-led business transformation. The next opportunity is to move beyond technology delivery toward intelligent, outcome-driven services, including a Services as Software model that can help CORT scale innovation with greater speed and agility. We are proud of what the Mastek and CORT teams have accomplished together and excited about the value we can create in the next chapter,” said Mithun Shenoy, SVP and Head of Retail, CPG, CMT & Manufacturing, Mastek. “Mastek’s recognition in the ISG Paragon Awards reflects the strength of its partnership with its client and its ability to translate technology expertise into meaningful business outcomes. This achievement demonstrates the value of combining innovation, execution excellence and a deep understanding of client priorities to deliver transformation that makes a lasting difference. We congratulate Mastek and its client on this well-deserved success,” said John Boccuzzi Jr., Partner & President, ISG Research. The award recognizes a partnership built on long-term collaboration, continuous innovation and measurable business outcomes. More importantly, the Mastek-CORT relationship demonstrates how a technology partnership can continuously evolve—from digital modernization and commerce transformation to managed services and toward an AI-led, outcome-driven model for continuous business transformation.
