  • Applications are submitted and tracked directly through the official iDEX portal at idex.gov.in.

What the iDEX Challenge is designed to do

India's defence modernisation depends heavily on technologies that were historically developed only by a small number of large public sector units and select private contractors. iDEX was created to widen that base by directly engaging startups, MSMEs and individual innovators who can bring faster, more original solutions to the Armed Forces' technology needs.

The programme sits within the Defence Innovation Organisation, which provides high-level policy guidance, while iDEX itself runs the funding and selection process with functional autonomy from day-to-day ministry operations.

Who can apply for the iDEX Challenge?

  • Startups recognised and defined by the Department for Promotion of Industry and Internal Trade, Ministry of Commerce and Industry
  • Any Indian company incorporated under the Companies Act, 1956 or 2013, that primarily qualifies as a Micro, Small or Medium Enterprise under the MSME Act, 2006
  • Individual innovators, who are encouraged to apply and can route their application through a research or academic institution
  • Applicants must generally form a registered startup entity before signing the final grant agreement, even if they applied as an individual innovator

Defence India Startup Challenge versus Open Challenge

TrackHow it works
Defence India Startup Challenge (DISC)The Ministry, in partnership with the Atal Innovation Mission, publishes specific problem statements from the Armed Forces and Defence PSUs, and applicants propose solutions to a named challenge.
iDEX Open ChallengeInnovators propose original technology in open-ended domains such as aerospace, autonomous systems, artificial intelligence, quantum technologies and advanced materials, without a pre-defined problem statement.

Grant amount and how it is disbursed

Selected applications are funded up to ₹1.5 crore, structured as equity or another relevant financial instrument rather than a simple cash award. The funds are released in tranches, with each tranche tied to a milestone agreed with the high-powered selection committee, so disbursement tracks actual progress on the prototype or product.

Beyond the grant, winners may also secure equivalent matching contributions and gain entry to accelerator programmes run by iDEX partner incubators, where they receive technology and business development support from mentors with defence and entrepreneurship experience.

Evaluation process

  • Applications are screened by a duly constituted High-Powered Selection Committee made up of defence and technology experts.
  • The committee assesses technical feasibility, relevance to the stated problem statement or open challenge domain, team capability and the tentative business plan submitted with the application.
  • Shortlisted applicants typically present their solution before an iDEX jury before final selection and grant agreement.
  • Once selected, ongoing funding tranches depend on meeting the milestones set at the time of selection.

How to apply for the iDEX Challenge

  • Register on the official iDEX portal at idex.gov.in and complete the innovator or startup profile.
  • Review open challenges under the Defence India Startup Challenge or the iDEX Open Challenge and choose the one that matches your technology.
  • Fill in entity details for startups and MSMEs, or proceed directly for individual innovators.
  • Submit proposal details, including the problem statement being addressed, funding level sought, technical approach, relevant patents or research papers, and a tentative business plan.
  • Track the application status on the portal and respond promptly to any clarification requests from the selection committee.
