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
403 companies with a company-register match, 199 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
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.
