Why this page exists - and how to read it
A one-page brief of this sector: its filing trend, the problems being worked on, the technologies in play, who files most, foreign interest, and a sample of the startups we've mapped to it. Each panel is a door - most drill into a fuller view.
- Investors
- Read the trend and foreign share first - momentum plus outside interest - then scan the roster for patent-backed startups.
- Founders & operators
- The problems list is a whitespace map: crowded themes are validated demand, thin ones are open ground.
- Corporate & R&D
- Top filers and technologies show who to benchmark and where the sector is consolidating.
- Policy & TTO
- The domestic-vs-foreign filing split signals where Indian players lead - and where outside applicants dominate.

When these companies were incorporated
158 companies with a company-register match, 26 of them with matched IP. Open a year to see the companies founded in it.
Incorporation dates come from the MCA register, which we have matched for about 69% of the deep-tech base - so this is the shape of the cohort, not a census of it. It is also not the DPIIT recognition date, which can be years later.

Briefings on this sector
funding brief
Space Took a Quarter of the RDI Fund's First Approvals. AI Took ₹3 Crore.
We set TDB's first 22 RDI approvals against where India's deep-tech companies and patent filings are. Space took a quarter of the money from 2% of the companies on our list. AI took 0.1%. Karnataka sent nearly a third of the proposals; Gujarat sent four.
funding brief
Missions Outspend Investors 115 to 1 in Chips. In Space, Investors Lead 7 to 1.
We set ten government missions and funds against the private rounds on our record in the same sectors. In chips, quantum, critical minerals and green hydrogen, the state has committed more than every private round the sector's startups have on our record. In space, robotics, defence, health and mobility, investors have put in more. AI is close to level.
funding brief
The RDI Fund Pays Half. How Many Indian Deeptech Companies Can Raise the Other Half?
The ₹1 lakh crore RDI Fund will finance no more than half of a project; the company must find the rest. The first 22 approvals needed a median ₹101 crore each from their own or private sources. In the past year, 47 deep-tech companies on our list closed a private round of ₹100 crore or more.
funding brief
The RDI Fund's First 22 Companies: ₹2,192 Crore Approved, ₹376 Crore Paid
The Technology Development Board, the first manager to lend from India's ₹1 lakh crore Research, Development and Innovation Fund, has approved 22 companies for ₹2,192 crore against projects worth ₹4,744 crore. By 30 September it had paid ten of them ₹375.69 crore. Here is the full list, what each is building, and what our data says about them.
