Competitive Landscape
The competitive landscape includes Accenture, Capgemini, Cognizant, HCLTech, Infosys, Tata Consultancy Services (TCS), and Thoughtworks. These providers compete across application modernization, cloud engineering, product development, integration, and enterprise software programs.
Accenture and Capgemini provide broad custom development and transformation coverage across large enterprise programs. Cognizant focuses on application modernization and product engineering, while HCLTech and Infosys add cloud engineering and application lifecycle capabilities.
Tata Consultancy Services (TCS) brings large-scale modernization and migration capabilities. In May 2025, TCS launched its GenAI and Agentic AI-powered TCS MasterCraft platform to support legacy-system modernization, automated conversion, and business-logic extraction.
Thoughtworks focuses on product engineering and digital products. The report also cites a June 2025 Thoughtworks modernization case involving more than 15 million lines of legacy code, illustrating the complexity that can arise during large application-renewal programs.
Competition through 2036 is expected to center on domain knowledge, architecture capabilities, secure development practices, modernization automation, and the ability to retain client knowledge across long-running programs.
Analyst Opinion
Shambhu Nath Jha, Senior Analyst at Fact.MR, states:
“Custom software development is drawing attention because enterprises are buying ongoing engineering capacity instead of isolated coding effort. Adoption is expected to favor providers that join domain context with modernization discipline and secure delivery controls. Providers seeking durable account access should combine architecture skills and product ownership with testing inside the client’s production environment.”
