iDEX Open Challenge 2026

The iDEX Open Challenge 2026 is designed for Indian startups, innovators, engineers, and MSMEs developing technologies with potential defence and aerospace applications. If your startup is building deep-tech solutions that can address military, aerospace, or national security challenges, this program provides a pathway to secure government-backed support, funding, and engagement opportunities.

Organized under Innovations for Defence Excellence (iDEX), an initiative of the Ministry of Defence’s Defence Innovation Organisation (DIO), the challenge seeks innovative technologies that can strengthen India’s defence capabilities and technological self-reliance. The program focuses on identifying and supporting solutions across areas such as autonomous systems, intelligent machines, advanced materials, predictive technologies, and other defence-relevant innovations.

Selected applicants can receive grant funding, technical support, access to defence stakeholders, and opportunities to engage directly with the armed forces and defence ecosystem. The challenge is intended to help innovators move from concept and prototype stages toward practical deployment and adoption within defence and aerospace applications.

The program is particularly relevant for founders working in sectors where commercialization depends on government procurement, testing, certification, or strategic partnerships. By connecting innovators with defence users and institutions, iDEX creates a structured route for translating emerging technologies into real-world defence applications.

From a founder’s perspective, this opportunity is most valuable for startups developing deep-tech products that require validation, testing, and access to defence stakeholders. Teams building technologies with clear defence or aerospace relevance are likely to benefit the most from the funding, mentorship, and procurement pathways offered through the program.
