Defence-Tech & Deep Tech: Why Startups in These Sectors Are Getting a 2025 Boost
The year 2025 is not just another funding cycle—it’s a strategic inflection point. Geopolitical shocks (Ukraine 2022–25, Taiwan tensions), border realities, and the global race for technological sovereignty have forced India to pivot from defence importer ($80 billion cumulative) to exporter and innovator. The result? A $5–7 billion defence-tech and deep-tech funding surge in 2025 (up 150% YoY), 1,200+ startups (from 200 in 2020), and policy oxygen never seen before: iDEX winners now get Rs 10 crore grants + production orders, 70% indigenisation target under DAP 2020, and Rs 500 crore Defence Innovation Fund launched in Budget 2025.
From IdeaForge’s drones guarding LAC to Tonbo Imaging’s night-vision tech in Indian Army rifles, these startups are no longer “nice-to-have” — they’re national security assets. As X defence-tech founders declare, “2025: When deep tech became defence tech,” this 1,050-word surge analysis spotlights the pioneers, the policy tailwind, and why India’s next unicorns will wear combat boots and quantum chips. Defence isn’t buying tech anymore. It’s funding it.

- Make-II: No DPP approval needed for prototypes
- Defence Testing Infrastructure: 50% funding for private ranges
- Export Push: Open General Export Licence (2025)
X: “iDEX: From Rs 50 Cr to Rs 500 Cr—defence-tech’s steroid shot.”
The Deep Tech Overlap: Dual-Use is the New Dual-Purpose
60% of 2025 defence-tech startups are dual-use:
- AI vision → battlefield + civilian surveillance
- Hypersonics → missiles + space launch
- Quantum sensors → navigation + encryption
Result? 25% higher valuations than pure civilian deep tech (Bain 2025).
Challenges: Still a Battlefield
- Clearance delays: 6–18 months for export licences
- Funding gap: 70% still early-stage, <Rs 50 Cr
- Talent: 55% skill gaps in defence-specific domains
X: “Boost yes—but bureaucracy still shoots friendly fire.”
The 2030 Horizon: $50 Billion Defence-Tech Market
By 2030:
- $50B domestic market
- $15B exports
- 50 unicorns in defence & deep tech
- 5 lakh direct jobs
India won’t just buy defence tech.
It will define it.
2025 isn’t a boost. It’s a breakout.
