What Megasoft does

Sigma Advanced Systems Limited (formerly Megasoft Limited) is an integrated defence and aerospace manufacturing company headquartered in Hyderabad, India. Founded in 1994 as Megasoft Limited and rebranded in February 2026 following approvals from BSE and NSE, the company operates as a publicly listed Indian public limited company with operations spanning the entire defence and aerospace value chain.

The company operates two primary product divisions. The defence portfolio comprises mission-critical systems and subsystems across six domains: Counter-UAS, Unmanned Aerial Systems, Missile Systems, Radar & Electronic Warfare, Avionics, and Naval Systems. The aerospace manufacturing portfolio offers precision services including Complex Machining, Fabrication & Welding, Systems Integration, and Surface & Metal Treatments. Supporting both divisions are capability services spanning Design & Engineering, Software Development, Testing & Validation, Lifecycle Support, Global Supply Chain, and Quality Control. The company holds AS9100D aerospace quality certification and serves global aerospace OEMs and prime defense contractors; named customers include Rolls-Royce (₹3,800 crore aerospace parts contract) and North American defense contractors (₹107 crore defense components and ₹22 million artillery shell bodies export orders). Leadership comprises G V Kumar as Co-Founder, Managing Director, and CEO, and Shridhar Thathachary as Chief Financial Officer.

The business model is B2B enterprise project-based, with multi-year contract pricing negotiated on specifications, volumes, and delivery timelines. Revenue is generated primarily through direct sales to aerospace OEMs and defense prime contractors rather than through traditional distribution channels. Geographic reach spans South Asia (India) and North America (USA) with global delivery capability. The company is classified as for-profit and is publicly listed on Indian stock exchanges under its new Sigma Advanced Systems identity.
