Constelli's story began long before the company had a name. Satya Gopal spent 10 years at National Instruments watching a problem compound across India's defense ecosystem: brilliant operators on the ground, but no indigenous electronic warfare systems to support them. Meanwhile, Avinash Chenreddy was deep in the trenches of a startup, developing advanced signal-processing solutions. The two met unexpectedly through an NGO they both volunteered with, and a chance connection quickly turned into a rhythm of late-night calls and whiteboard sessions. Satya and Avinash started taking on unsolved problems from India's defense electronics labs, designing elegant technological solutions to challenges that previously seemed insurmountable.

The early whiteboard sessions became a pipeline of breakthroughs, and by 2017, Satya and Avinash formalized their efforts with a company name: Constelli. The early years were spent in heads-down, capital-efficient R&D, working closely with end users to ensure every solution was grounded in real operational needs. Three to four years ago, that foundation fueled a shift from pure development to commercial scale.

Today, Constelli stands on deep technical roots, operator-validated products, and the same shared conviction that first brought Satya and Avinash together: India's resilience requires world-class defense electronics built at home. General Catalyst is proud to lead their Series A.

The Future of Electronic Warfare for India

India is entering a decisive decade for defense electronics and electronic warfare, driven by rising geopolitical tensions, rapid advancement of its neighbors' electronic warfare capabilities, and a national mandate for technological self-reliance. Modern conflicts have made control of the electromagnetic spectrum as critical as exquisite hardware, pushing India to rapidly expand AI-first indigenous electronic warfare capabilities.

Constelli has spent years solving the hardest signal processing problems India's defense labs face and creating systems that work under real operational constraints. As India seeks domestic champions in defense electronics, we believe Constelli has the credibility and the technology to lead.

Delivering for India’s Defense

Today, Constelli delivers radio frequency simulators, telemetry systems, and precision test equipment which are being used by various labs within India’s defense research organisation (DRDO). The company is now expanding into counter-drone systems, where demand is accelerating across military and critical infrastructure.

Multiple labs within India's Defense Research and Development Organization (DRDO) also now rely on Constelli as a co-development partner for electronic warfare systems. This positions the company at the center of India's upcoming modernization programs across air and naval platforms. 

Underpinning all of it is Constelli's edge-AI architecture, which enables real-time threat classification and autonomous spectrum response, capabilities that cannot be imported or transferred by foreign vendors.

Constelli's early technical wins and deep integration with end users give it a powerful trajectory to shape the future of India's electronic warfare ecosystem. We’re proud to partner with Satya and Avinash as they create the foundational capabilities essential to India’s resilience. General Catalyst is committed to building India’s defense and industrial sovereignty by partnering with the best founders in India.
