In 2007, they developed India's first and only prediction software for stealth, which makes an aircraft or warship near-invisible to enemy radar. Their code for stealth is being used in the most advanced Make in India projects - such as the Advanced Medium Combat Aircraft and in fine-tuning missile seekers to home onto their targets more effectively.
Partnering Garden Reach Shipbuilders and Engineers (GRSE) in designing an inshore patrol vessel, Zeus reduced its stealth signature by 70 per cent.
Along the way, they won the Lockheed Martin India Innovation Growth Medal, which is a highly competitive programme for honouring innovation in India and helping commercialise successful innovations.
"Very early, we recognised the need to indigenise more deeply by not just accumulating manufacturing know-how, but mastering the process of designing those products and improving them," said Jain.
In 2009, they won their first design and development order for a testing facility for the DRDO, which incorporates a rocket sled that moves at a velocity of 1,800 kilometres per hour - the only such facility in Asia.
By 2010, top scientists in DRDO, BrahMos and HAL saw the potential of Zeus' young team and began mentoring them in developing advanced technologies that fed into projects like the integration of the BrahMos missile into the Sukhoi-30MKI.
To work in this field, one requires the highest level of aerospace certification and this was accorded to Zeus by the DRDO's certification agency, Centre for Military Airworthiness and Certification (CEMILAC).
In March 2018, Zeus became the first small company to be awarded a project under the defence
ministry's Technology Development Fund to develop a sea water pump made of composite materials that are light and do not corrode. This pump is currently being tested. If it is successful, Zeus will be the world's second company - after US firm, SIMSITE - to have succeeded in this.
The Department of Scientific and Industrial Research (DSIR) has recognised Zeus as an R&D company, which brings in tax benefits and opportunities to work in government-funded R&D programmes with foreign collaborators. Already, Zeus has executed over 200 assignments in defence
for the DRDO, DPSUs and major private defence firms in India. These include designing a framework for "low noise aircraft wing" for Airbus Innovation Works, which funds futuristic technologies.
Underscoring its focus on cutting edge R&D, the company is guided by a technology team composed of IIT Bombay professors and alumni. It has raised money once from an angel investor, but now says its on-going projects provide all the funds they need.
