HCLTech is one of India's 'Big Four' IT services firms, alongside TCS, Infosys and Wipro. It works for global enterprises in financial services, manufacturing, technology, life sciences, telecom, retail and the public sector, with more than 220,000 employees in 60 countries. Its mix differs from peers because roughly a quarter of revenue comes from engineering services and owned software rather than traditional IT outsourcing. The company is headquartered in Noida, India.
HCLTech sells technology work to large enterprises under multi-year contracts, and it reports three segments. IT and Business Services (73.8% of FY2026 revenue) covers application management, cloud and infrastructure operations, cybersecurity, digital and business process services. Engineering and R&D Services (17.0%) designs software, firmware, chips and embedded systems for product companies in semiconductors, automotive, aerospace, telecom and medtech. HCLSoftware (9.5%) sells subscriptions, support, licenses and SaaS for products such as BigFix, AppScan, Unica, Domino and Actian, many of them bought from IBM in 2019. Most delivery staff work from India, which keeps costs below what clients would pay for onshore teams.
