Quick Take
- Indian defence tech raised $68 Mn in 2025, about 13% of all deeptech funding, per Inc42.
- Seed-stage funding rose 18% to $478 Mn in H1 2026, even as overall funding fell 9%.
- New pre-seed and seed rounds for Kepler Aerospace, Alteon and others show where the money is moving next.
India’s defence and aerospace startups are drawing sharp early-stage investor interest in 2026. The money is arriving at the pre-seed, seed and pre-Series A stages. Cheques are small, but deal activity is rising fast.
The backdrop is a tighter market. Indian startups raised $5.2 Bn across 501 deals in the first half of 2026. That was down 9% year-on-year, according to Inc42’s H1 2026 funding report.
Late-stage money pulled back hardest. Deployment into mature startups fell 27% to $2.2 Bn, and the median late-stage cheque dropped 68% to $10 Mn.
Early-stage capital moved the other way. Seed-stage startups raised $478 Mn in the same period, up 18% year-on-year. The median seed ticket held steady at about $1 Mn.
How Big Is India’s Defence Tech Funding?
Defence tech sits inside this early-stage pocket. The sector raised $68 Mn in 2025, about 13% of all Indian deeptech funding that year. Deeptech as a whole drew $533 Mn, per Inc42.
That single year did most of the work. Defence tech has raised roughly $78 Mn in the last decade. The base is small. The direction is not.
StartupFeed Insight
The number that matters is not the $68 Mn, it is the mix. In a year when the median late-stage cheque fell 68%, capital that keeps flowing chooses early, cheap, and strategic bets. Defence hardware is exactly that: small first rounds, heavy government cover, and a buyer who is the state. Watch the pre-Series A band into 2027. Expect at least three Indian defence or aerospace startups holding iDEX prime contracts to close a Series A above $5 Mn by the end of FY27, as grants convert into private cheques.

Which Defence Startups Raised Money in 2026?
Recent deals show where the interest is landing. Kepler Aerospace raised $8 Mn in a seed round led by Blue Ashva Capital in early September 2026, Entrackr reported. The startup builds space infrastructure and mission systems.
Kepler also leans on the state. It holds about $4 Mn in grants under the government’s iDEX programme, and says it has won two iDEX prime contracts for defence space work.
Other early rounds fit the pattern. Bengaluru’s Alteon raised a $2.5 Mn pre-seed on September 2, 2026, led by Lachy Groom, to build long-endurance aircraft.
Second cheques are landing too. Aadyah Aerospace raised Rs 31.5 crore, or $3.3 Mn, in a Series A led by Helios Holdings in June 2026. That followed an earlier pre-Series A round.
Aadyah was founded in 2016 by former ISRO scientists. It builds propulsion, avionics and guidance systems for space and defence. EyeRov, an underwater-drone maker, raised a $1.2 Mn pre-Series A from Unicorn India Ventures.
| Startup | Round | Amount | Lead investor |
|---|---|---|---|
| Kepler Aerospace | Seed | $8 Mn | Blue Ashva Capital |
| Aadyah Aerospace | Series A | Rs 31.5 Cr ($3.3 Mn) | Helios Holdings |
| Alteon | Pre-seed | $2.5 Mn | Lachy Groom |
| EyeRov | Pre-Series A | $1.2 Mn | Unicorn India Ventures |
Why Are VCs Backing Defence Startups Now?
Government money is doing the early de-risking. The Innovations for Defence Excellence scheme, called iDEX, gives equity-free grants. It is now engaged with more than 650 startups and MSMEs, according to government data.
The state also pulls in private capital. The iDEX Investor Hub has drawn pledges of over Rs 200 crore from Indian investors. Much of the early risk is absorbed before a VC arrives, so a private cheque can follow.
Policy and events sharpened the shift. Inc42 reported that Operation Sindoor was the inflection point for the sector. It moved defence tech from the margins to the mainstream and exposed India’s reliance on imports.
Indian VCs took note. In its H1 2026 survey, Inc42 found 64% of investors planned to raise their venture allocation in the second half. Another 61% said the semiconductor mission had shaped their deeptech thesis.
What Should Founders Watch Next?
Drones still dominate the sector, with names like Raphe mPhibr, ideaForge and Garuda Aerospace leading. The newer money is spreading into propulsion, satellites, autonomous systems and defence-grade sensing. That widening is the real signal for anyone raising a first round now.
What this means for you: an iDEX grant plus a named prime contract is now the clearest way to pull a pre-Series A cheque forward. Pair government validation with a defensible hardware moat before you pitch.
