iDEX (Innovations for Defence Excellence) is the flagship defence-innovation framework of India's Ministry of Defence (MoD), launched by Prime Minister Narendra Modi on 12 April 2018 at the Defence Expo in Chennai. It was conceived to break the historic monopoly of Defence Public Sector Undertakings (DPSUs) and the Ordnance Factory Board over military research and procurement by drawing startups, micro, small and medium enterprises (MSMEs), individual innovators, research and development institutes, and academia into the defence ecosystem. iDEX is operationalised and managed by the Defence Innovation Organisation (DIO), a not-for-profit company registered under Section 8 of the Companies Act, 2013, funded jointly by Hindustan Aeronautics Limited (HAL) and Bharat Electronics Limited (BEL). The scheme aligns with the broader policy thrust of Atmanirbhar Bharat (self-reliant India) and the Defence Acquisition Procedure (DAP) 2020, which created procurement categories favouring indigenously designed and developed equipment.
The principal mechanism through which iDEX operates is the Defence India Startup Challenge (DISC), launched in August 2018 in partnership with the Atal Innovation Mission. Under DISC, the armed forces and DPSUs articulate specific capability gaps or problem statements, which are released as open challenges. Applicant startups and innovators submit proposals against these statements; shortlisted entities pitch before an evaluation committee. Winners are awarded grant-in-aid funding through the Support for Prototype and Research Kickstart (SPARK) framework, which provides up to ₹1.5 crore per winner to develop a working prototype. Funds are disbursed in milestone-linked tranches against a Project Management Agreement, with the awardee retaining intellectual property rights while the MoD secures the option to procure the resulting product.
Beyond DISC and SPARK, iDEX has expanded through several variants to capture larger and more complex technologies. iDEX Prime, introduced to bridge the gap between SPARK grants and full-scale induction, raises the funding ceiling to ₹10 crore for projects requiring greater capital. The ADITI (Acing Development of Innovative Technologies with iDEX) scheme, launched in March 2024 under Defence Minister Rajnath Singh, targets critical and disruptive deep-tech with grants up to ₹25 crore, focusing on areas such as artificial intelligence, quantum technology, hypersonics, and autonomous systems. iDEX also runs Open Challenges (problem statements not tied to a fixed DISC cycle), the Partner Incubators network, and DAP 2020 provides a dedicated procurement category that allows the Services to buy iDEX-developed products without competitive re-tendering up to defined value limits.
By 2024, iDEX had engaged with over 400 startups and MSMEs and signed contracts across hundreds of problem statements spanning all three Services. Notable inductions include unmanned systems, anti-drone technologies, AI-based surveillance platforms, and secure communication solutions. In a landmark development, the MoD crossed 400 iDEX contracts, and the Cabinet Committee on Security in 2021 approved a budgetary outlay of approximately ₹500 crore for iDEX and DIO over five years. The scheme is administered from New Delhi with regional engagement through Partner Incubators such as IIT Hyderabad, FICCI, and T-Hub, and high-value contracts have been signed during DefExpo and Aero India editions in Bengaluru and Gandhinagar.
iDEX should be distinguished from adjacent instruments with which it is frequently conflated. The Technology Development Fund (TDF), administered by the Defence Research and Development Organisation (DRDO), also funds indigenous development but targets established MSMEs and larger industry for component and subsystem development, with different ceilings and a DRDO-centric evaluation. The Make procedure categories (Make-I, Make-II, Make-III) under DAP 2020 govern government-funded and industry-funded prototype development at programme scale, whereas iDEX deliberately addresses the early-stage, high-risk innovation segment populated by startups. iDEX is therefore positioned upstream of mainstream acquisition, functioning as a de-risking and discovery layer rather than a primary procurement route.
Controversies and structural challenges persist. Critics note that the transition from successful prototype to bulk procurement order—the so-called "valley of death"—remains the principal failure point, as the armed forces' lengthy trial and induction cycles can outlast a startup's runway. The relatively modest grant ceilings, even under iDEX Prime and ADITI, are sometimes inadequate for capital-intensive aerospace and missile technologies. Intellectual property and export-control questions also arise when iDEX-funded firms seek foreign markets. In response, the MoD has progressively raised funding limits, introduced ADITI for deep-tech, and used DAP 2020 provisions to fast-track procurement of iDEX products, while emphasising single-stage trials and reduced documentation for startups.
For the working practitioner—the UPSC aspirant addressing GS Paper III on indigenisation and defence, the policy researcher, or the desk officer tracking defence-industrial reform—iDEX exemplifies the shift from a state-monopoly defence model toward a startup-driven innovation ecosystem. It is a recurring examination topic precisely because it intersects self-reliance, the Make in India and Atal Innovation Mission policy architecture, and the modernisation of military procurement. Understanding iDEX requires holding together its institutional anchor in the DIO, its instruments (DISC, SPARK, iDEX Prime, ADITI), and its relationship to DAP 2020 and DRDO's TDF—a combination that captures both the ambition and the unresolved tensions of India's contemporary defence-acquisition strategy.
Example
In March 2024, Defence Minister Rajnath Singh launched the ADITI scheme under iDEX, offering grants up to ₹25 crore for deep-tech startups working on hypersonics, AI, and quantum technologies for the armed forces.
Frequently asked questions
iDEX is managed by the Defence Innovation Organisation (DIO), a Section 8 not-for-profit company funded jointly by HAL and BEL. The Cabinet Committee on Security approved a budgetary outlay of roughly ₹500 crore over five years in 2021, channelled through grant-in-aid instruments like SPARK.
