The Business behind the Battlefield

If you ask any AI chatbot or read the latest mainstream headlines, you’ll hear that Indian defence tech is having a massive moment. And honestly? The tailwinds are real. The domestic private sector share of defence production has jumped from a tiny 2% a decade ago to nearly 24% today, backed by a massive ₹6.81 lakh crore budget for FY26.

However, macro tailwinds do not automatically yield sustainable business models. For founders and allocators, the critical question is operational: What structural mechanics allow an early-stage defence startup to transition into a scalable enterprise?

An iDEX win, a great chat with the DRDO, or a single prototype pilot doesn't mean you’ve built a sustainable company. At Malpani Ventures, we dug into the data of 127 iDEX winners from recent years. The honest takeaway? While 80 are still active, most are trapped in the long, brutal valley between a working prototype (TRL 3-6) and predictable commercial scale. Only about 10% have managed to scale meaningfully past the ₹40 crore revenue mark.

Building a defence-tech product is hard. Building a repeatable, survival-ready defence-tech business is much harder.

The 4 survival hurdles founders must cross

1. The TRL-to-Order Valley: Moving from a bench prototype to field-readiness (TRL 7 to 9) takes 18 to 24 months of grueling field trials, certification, and endless re-work. You have to fund all of this out of pocket before a single Purchase Order lands.
2. Brutal Working Capital Demands: Defence orders are massive, but fulfilling them requires heavy upfront cash for component sourcing, manufacturing, and deployment long before the cash actually hits your bank account.
3. Structurally Lumpy Revenue: Forget smooth, predictable SaaS-like ARR. A defence startup can easily have an incredible year followed by two flat ones. Your capital plan has to expect and survive these delays.
4. The Procurement Literacy Test: The founders who succeed aren't just brilliant engineers; they are the ones who understand the complex web of how the military actually buys things.

How to Stay Alive and build a Moat

Through our deep dives with founders and operators over the past year, the winners are succeeding by changing their playbook:

• The Barbell Revenue Model: They don't get stuck in the middle doing bespoke, one-off cash-guzzling projects. Instead, they use a high-velocity, short-cycle commercial/dual-use product to fund the daily payroll, while running a slow-burn, certified defence platform on the other end to build their ultimate moat.
• Winning a Tier-1 Sponsor Early: Don't try to sell to five buyers at once. Focus your first 24 months on getting validated by just one tier-1 buyer like HAL, BEL, or a specific DRDO lab- even at zero margin. In this industry, a ₹2 crore company with a solid vendor registration and a tier-1 customer is fundamentally stronger than a ₹5 crore company selling to mid-tier integrators with zero government clearance.

Note: Based on data available on Tracxn and publicly available information

The data reinforces the core thesis: iDEX creates entrants, not businesses. The valley between winning a challenge and building a repeatable company is where most of this cohort is still stuck.

Our View at Malpani Ventures

We are for durable, capital-efficient businesses. As a family office, we aren't bound by strict fund life-cycles. We know the journey to build a true defence giant takes closer to a decade, not a quick 4-6 year VC flip.

If you are a founder team ideally combining an experienced operator who has worn the uniform with a killer silicon engineer and you are navigating the TRL 5-8 phase with a disciplined product wedge, we’re built to stay the course with you.

Building a business is easily the hardest thing you can do. Building one in defence tech? That’s next-level. But the founders grinding away in labs, bunkers and garages right now are as important to this country's future as the soldiers on the front line
