Historically, India's aerospace and defence sector was an impenetrable fortress for startups, dominated almost entirely by large Defence Public Sector Undertakings (DPSUs). This changed dramatically with the launch of the Innovations for Defence Excellence (iDEX) framework, managed by the Defence Innovation Organisation (DIO).
The flagship program within this framework is the Defence India Startup Challenge (DISC). It flips the traditional procurement model: instead of the military writing complex tenders for finished products, they release "problem statements" to the startup ecosystem.
If you are a startup founder with a deep-tech or hardware solution, here is exactly how to navigate DISC to secure your first ₹1.5 Crore in non-dilutive prototyping capital.
Understanding the Funding Tiers
Before applying, you must understand the financial structure of the iDEX ecosystem. Funding is heavily tiered based on the complexity and strategic importance of the technology:
- Standard DISC Grant: Up to ₹1.5 Crore. This is the entry point for most startups, designed to fund the transition from a verified idea to a working prototype.
- iDEX Prime: Up to ₹10 Crore. Designed for startups that have graduated from initial prototyping and require significant capital to scale a highly complex, capital-intensive technology.
- ADITI Scheme: Up to ₹25 Crore. Reserved for absolute cutting-edge, strategic, and critical defence technologies.
This guide focuses on securing the foundational ₹1.5 Crore standard DISC grant.

Step 1: Verify Your Eligibility
The Ministry of Defence operates with strict compliance rules. To be eligible for DISC, you must be one of the following: A Startup officially recognized by the Department for Promotion of Industry and Internal Trade (DPIIT). An MSME incorporated under the Indian Companies Act. An Individual Innovator* (such as a university researcher), provided you incorporate a company before the grant is formally disbursed.
Step 2: Select a Military "Problem Statement"
Unlike open-ended grants, DISC is highly prescriptive. The Army, Navy, Air Force, and various DPSUs release highly specific "Problem Statements" (e.g., 'Secure communication links for unmanned underwater vehicles' or 'AI-driven predictive maintenance for fighter jets').
You must select a problem statement where your core technological capability aligns directly with the military's stated need. Attempting to force-fit a civilian product into a military problem statement without significant, bespoke modification is the most common reason for rejection.
Step 3: Propose a Milestone-Driven Architecture
When you submit your proposal through the official iDEX portal, you are not just pitching an idea; you are pitching a technical execution plan.
The High-Powered Selection Committee evaluates proposals based on technical feasibility and commercial viability. Crucially, the ₹1.5 Crore grant is not given as a lump sum. It is disbursed in strict tranches.
Your application must break down your prototype development into 4 to 5 clear, verifiable technical milestones. For example: Milestone 1 (Month 3): Software architecture finalized and initial algorithms trained (Tranche 1 release). Milestone 2 (Month 6): Hardware integration of sensor suite complete (Tranche 2 release). Milestone 3 (Month 12):* Successful field test in simulated environment (Tranche 3 release).
Step 4: Engage with the Nodal Officer
If your proposal is shortlisted, you will be assigned a "Nodal Officer"—an actual officer or engineer from the military branch that issued the problem statement. This is the most valuable part of the iDEX program. Engage deeply with them during the development phase. Their feedback ensures your prototype survives actual military field trials, which is the ultimate requirement to secure a production contract post-DISC.
