Chennai, Tamil Nadu
Data Patterns (India) Limited is a prominent, vertically integrated defense and aerospace electronics solutions provider catering to the indigenously developed defense products industry in India. Established originally in 1985 by founder Srinivasagopalan Rangarajan and later incorporated as Indus Teqsite Private Limited in November 1998, the company has built an operational history spanning over three decades. Headquartered in Chennai, Tamil Nadu, Data Patterns operates as a key independent, promoter-led public entity listed on both the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE) under the ticker DATAPATTNS. The core business model of Data Patterns is built on a "Design to Delivery" framework, specializing in the in-house design, development, manufacturing, and servicing of high-reliability electronic systems. The company possesses deep domain expertise across multiple high-technology defense verticals, including radar and radar subsystems, electronic warfare, communication systems, avionics, space systems, satellites, automated test equipment (ATE), and cockpit displays. Leveraging a library of over 1,000 reusable building blocks, the company efficiently minimizes development cycle timelines for complex military systems, positioning itself to secure high-margin developmental contracts that subsequently mature into high-volume production orders. Operationally, Data Patterns runs its manufacturing and design efforts out of a 10.28-acre facility located at the SIPCOT IT Park in Siruseri, Chennai. This advanced industrial site features approximately 200,000 square feet of built-up space, which includes an electronics manufacturing services (EMS) assembly line capable of producing 600 boards per day, dedicated workstations for module testing, a large-scale system integration hangar for radar and electronic warfare vehicles, and a certified 100,000-class clean room designed for satellite integration. To support its sophisticated engineering requirements, the company maintains a highly skilled workforce; as of mid-2025, its total headcount reached approximately 1,545 employees, with over 1,000 qualified engineers comprising roughly 68% of the total staff. Financially, Data Patterns has demonstrated a trajectory of consistent growth, driven by India's strategic push toward defense localization and "Make in India" initiatives. For the fiscal year ending March 31, 2025, the company reported a total revenue of INR 755 crore, derived primarily from production contracts (53%), development contracts (42%), and services (5%). The company is virtually debt-free and maintains high profitability metrics, including a 37.6% CAGR in profit growth over a five-year period. It is governed by a board of directors led by Chairman and Managing Director Srinivasagopalan Rangarajan, and its high-reliability products have been integrated into several of India's major indigenous defense platforms, including the LCA-Tejas aircraft, Light Utility Helicopter, and the BrahMos missile system.
