The Bottom Line
At every stage of a deep tech venture, there is now a public instrument built for it. The founder's job is not to find money — it is to know which door to knock on, in which order. One flagship per stage:
| Your stage | What you need | The flagship instrument | Worth up to |
|---|---|---|---|
| S–01Researcher | Income and a lab, without leaving India | PMRF fellowship + SATHI instrument access | ₹80K/MO + ₹2L/YR |
| S–02Prototype | The first cheque, pre-incorporation | NIDHI PRAYAS grant, via a PRAYAS Centre | ₹40 LAKH |
| S–03Seed | Proof-of-concept and market-entry capital | Startup India Seed Fund (grant + soft debt) | ₹70 LAKH |
| S–04First customer | A buyer before the market believes you | iDEX / ADITI challenges → procurement order | ₹25 CR |
| S–05Scale R&D | Non-dilutive money for the hard middle | DRDO TDF (defence) · RDI Scheme (all sectors) | ₹50 CR |
| S–06Every stage | Time, tax room, and cheap IP | Deep Tech Startup recognition (Feb 2026) | 20 YEARS |
| S–07Growth equity | Patient capital on deep tech clocks | Sector funds: Space VC · Quantum T-Hubs · FoF 2.0 | ₹60 CR |
While you are still a researcher.
The state will pay you to stay in the lab — and lend you the instruments.
Most deep tech companies begin inside a laboratory, and the earliest form of government support is simply this: funding that lets a researcher keep working on hard problems in India rather than leaving.
Prime Minister's Research Fellowship
The PMRF is the government's counter-offer to a PhD abroad. It pays a monthly fellowship of ₹70,000 in the first two years, rising to ₹80,000 in the fourth and fifth, alongside a research grant of ₹2 lakh per year for equipment, contingency, and travel. Selection runs through the participating institutions — the IITs, IISc, IISERs, and central universities — either at admission or by upgrading from an existing doctoral programme. For a founder-to-be, its value is not only the stipend but the standing: PMRF work in an IIT laboratory is where several of the ventures described in this book began.
ANRF early-career and postdoctoral grants
The ANRF, established in 2024 as the successor to SERB, runs the main grant lines for researchers before and after the doctorate: the Prime Minister Early Career Research Grant for young faculty pursuing breakthrough work, and the National Postdoctoral Fellowship for researchers between thesis and independent career. Calls are published on the ANRF portal; proposals are made directly by the researcher through their host institution. Women researchers, including those returning from career breaks, have a dedicated channel in DST's WISE-KIRAN programmes, and DST's INSPIRE Faculty Fellowship funds a young scientist's first independent laboratory — the soil a large share of deep tech founders grow from.
Access to instruments: SATHI
Deep tech research fails without instrumentation few startups can afford to own. SATHI funds shared science and technology infrastructure centres at host institutions, open to outside researchers, MSMEs, and startups on a booking basis. Before budgeting crores for an electron microscope, it is worth checking whether a SATHI centre within reach already operates one.
Building the prototype.
Join an incubator first — the grants flow through institutions, not portals.
Between a research result and a fundable company sits the prototype — the stage private capital in India still avoids. This is where the public incubation network, several hundred institutions deep, carries the load. The practical first step at this stage is almost always to join an incubator.
NIDHI and the PRAYAS prototype grant
NIDHI is DST's umbrella for the entire incubation pipeline — over 180 technology business incubators, more than 10,000 startups supported. Its instrument for this stage is PRAYAS: a grant for turning an idea into a working prototype, up to ₹10 lakh in its standard form, and under the PRAYAS 2.0 guidelines up to ₹20 lakh through PRAYAS Centres and ₹40 lakh at Advance PRAYAS Centres for deep tech prototypes. It is open to individual innovators, not only incorporated companies — you apply to a PRAYAS Centre, which hosts you while you build. For many hardware founders this is the first cheque the venture ever receives.
GRANT ₹10–40 LAKH · OPEN TO INDIVIDUALS · VIA PRAYAS CENTRESThe incubation networks, by domain
Which network you join depends on what you are building. The Atal Innovation Mission runs over 72 Atal Incubation Centres with the widest geographic spread. In the life sciences, BioNEST bioincubators — more than 1,300 startups supported — provide the wet-lab infrastructure a biotech or medical-device venture cannot improvise. For software and emerging technologies, MeitY's TIDE 2.0 operates through academic institutions, while GENESIS extends the same support into tier-II and tier-III cities and STPI's NGIS adds ₹25 lakh seed cheques for software-product startups through the CHUNAUTI challenges. And the 25 Technology Innovation Hubs under NM-ICPS — ARTPARK at IISc for AI and robotics, TIH-IoT at IIT Bombay, IITM Pravartak — each run their own startup grants and residencies with laboratory access no generic incubator offers. Agritech has its own door: RKVY-RAFTAAR agribusiness incubators give pre-seed grants of ₹5 lakh and seed grants of up to ₹25 lakh at 85% coverage. In every case the route in is an application to the institution itself.
The first institutional money.
Public money is your real seed round: ₹20–70 lakh before a VC returns your call.
Once a company exists and a prototype works, the question becomes seed capital. In most sectors that means venture investors; in deep tech, the state is structurally the first investor, and its instruments at this stage are worth understanding precisely.
Startup India Seed Fund Scheme
The SISFS provides two tranches through empanelled incubators: a grant of up to ₹20 lakh for proof of concept, prototype validation, and product trials, released against milestones; and up to ₹50 lakh for market entry and commercialization, structured as convertible debentures or debt-linked instruments at an interest rate no higher than the prevailing repo rate, with tenure up to five years. Eligibility is specific: DPIIT recognition, and incorporation no more than two years before application. A founder applies on the scheme portal to three empanelled incubators at once; the incubator's committee decides. Over 2,490 startups funded through 213 incubators so far.
GRANT ₹20 LAKH + DEBT ₹50 LAKH · DPIIT-RECOGNIZED · ≤2 YEARS OLDBIRAC and the Biotechnology Ignition Grant
For life-science ventures, BIRAC is the seed funder of record. Its flagship BIG scheme provides ₹50 lakh as a grant over 18 months to take an idea to proof of concept — open to individual entrepreneurs and young startups, through BIRAC's partner incubators. Beyond BIG, BIRAC's ladder continues through SBIRI and PACE into product development, and into equity through LEAP and the AcE fund of funds — the closest thing India has to a continuous public capital escalator, covered in the sector stacks below.
GRANT ₹50 LAKH · 18 MONTHS · IDEA TO PROOF OF CONCEPTTechnology Development Board
The TDB occupies a niche no private lender does: debt and equity support for commercializing indigenous technology — capital for the long, asset-heavy middle of a hardware venture. Terms are set project by project against the commercialization plan, and since 2026 the TDB also manages ₹2,000 crore of RDI Scheme money as one of its first fund managers, with 22 projects approved in the first months.
The first customer.
Sell to the government early — defence has a paved path; elsewhere, plan for patience.
In deep technology the government is not only the funder of first resort but, in defence, health, energy, and infrastructure, the largest potential buyer — and the rules have been rewritten to let a two-year-old company sell to it.
iDEX: from challenge to procurement order
iDEX inverts the usual grant logic: the armed forces publish specific problem statements, and startups compete to solve them. Winners receive prototype funding of up to ₹1.5 crore under the SPARK grant, rising to ₹10 crore under iDEX Prime and up to ₹25 crore under ADITI for critical and strategic technologies. The decisive feature is what follows the prototype: a defined path to a defence procurement order. More than 400 startups now work in defence and aerospace through this route.
SPARK ₹1.5 CR · PRIME ₹10 CR · ADITI ₹25 CR · PATH TO PROCUREMENTGeM and the procurement exemptions
Less known and broadly applicable: a DPIIT-recognized startup selling to any government buyer is exempt from prior-turnover, prior-experience, and earnest-money-deposit requirements in public procurement, and the GeM Startup Runway gives innovative products a storefront without standard category requirements. These waivers remove precisely the barriers that lock a young company out of its natural first market. Government purchases from startups on GeM crossed roughly ₹19,000 crore in FY 2025-26.
Make-I, Make-II, and shared test infrastructure
Two defence procurement categories matter to founders. Under Make-I, the government funds up to 70% of prototype development, capped at ₹250 crore, with an assured procurement pathway on success. Under Make-II, industry funds its own prototype in exchange for an assurance of orders on successful trials — with categories reserved for startups and MSMEs. Alongside them, the Defence Testing Infrastructure Scheme has stood up seven accredited test facilities, turning the costliest bottleneck in defence hardware — certification — into a usage fee rather than capex.
Outside defence, the machinery is not yet built. Certification pathways for novel Indian products are incomplete, and tender rules were not written with startups in mind. This book argues procurement reform is among the highest-leverage changes available to the ecosystem — but a founder planning revenue today should treat non-defence government sales as a slow channel.
Growth and patient capital.
The 2025–26 reforms built the patient-capital layer India never had.
The stage at which Indian deep tech ventures have historically stalled — past seed, before scale — is the stage the government moved on most decisively in 2025 and 2026.
The RDI Scheme
The Research, Development and Innovation Scheme is the largest patient-capital commitment India has made: ₹1 lakh crore over six years, providing long-term financing at low or nil interest for private-sector R&D in sunrise and strategic sectors. The money flows through second-level fund managers — the TDB and BIRAC were appointed first, with ₹2,000 crore each — and the first cheques reached deep tech startups in May 2026. For a growth-stage company whose R&D horizon is longer than venture fund cycles, this is the instrument to track: the funds it capitalizes are only now coming into operation, and their mandates will define who gets funded.
₹1,00,000 CR · 6 YEARS · LOW/NIL INTEREST · FIRST CHEQUES MAY 2026The Fund of Funds — and its deep tech window
The Startup India Fund of Funds does not invest in companies; it invests in venture funds, which must then deploy into Indian startups. The first fund committed ₹11,148 crore across funds that have backed over 1,165 startups. The second, with a ₹10,000 crore corpus, is where the promised "deep tech fund of funds" actually lives: its April 2026 guidelines created a dedicated deep-tech AIF category with no corpus cap and fund life up to 18 years — an explicit acknowledgment that deep tech returns take longer than a standard fund's clock. A founder never applies directly, but it matters which venture funds are FoF-backed.
Credit without collateral: CGSS
Hardware companies need debt for capex and working capital, but their only real asset is IP — which Indian banks will not lend against. The Credit Guarantee Scheme for Startups shifts that risk to the government: guarantee cover of up to ₹20 crore per borrower (doubled in May 2025), covering 85% of default on loans up to ₹10 crore, with the guarantee fee halved for 27 champion sectors. It covers term loans, working capital, and venture debt through banks, NBFCs, and registered AIFs.
COVER ₹20 CR · 85% GUARANTEE · INCLUDES VENTURE DEBTThe quiet advantages.
Recognition, tax room, and cheap IP — benefits that compound for twenty years.
Not everything valuable arrives as a cheque. A set of structural benefits — several of them new in 2025–26 — compound quietly over a deep tech company's long life.
Deep tech recognition: 20 years, not 10
In February 2026, DPIIT rewrote the startup definition and created a formal Deep Tech Startup category: recognition for up to 20 years from incorporation (against 10 for regular startups) with a turnover ceiling of ₹300 crore — defined by R&D intensity and owned IP rather than sector. It is a direct answer to deep tech gestation cycles: a company building reactors or rockets no longer ages out of startup benefits before it commercializes. Recognition is free, on the Startup India portal, and it is the eligibility key to nearly everything else on this page.
The tax position, after the 2024–26 reforms
Three changes matter. The angel tax was abolished from FY 2024-25 for all investor classes — removing the valuation-dispute overhang that hit IP-heavy companies hardest. The Section 80-IAC holiday — 100% profit deduction for any three consecutive years chosen within the first ten — now covers startups incorporated up to April 2030, letting a founder time the holiday for the first profitable years after commercialization. And employees of certified startups can defer tax on exercising ESOPs for up to four years — a real weapon when competing for scientists against cash-rich employers.
Patents, faster and cheaper
A recognized startup pays roughly 80% less in patent fees and half the trademark fees, and qualifies for expedited examination — a first examination report in one to three months instead of one to two years. For a company whose value is its patent estate, compressing a five-year grant cycle to roughly one changes what the next funding round looks like. One honest note: the SIPP scheme that provided free patent-drafting facilitators lapsed in March 2026 without renewal, so professional drafting costs are currently the founder's own — though an MSME-registered startup can reclaim 75% of IPR filing costs (up to ₹1 lakh domestic, ₹5 lakh for international patents) under the MSME Innovative Scheme.
The sector stacks.
The biggest cheques hide below the missions — know your sector's agency.
Below the headline missions sits a layer of agency programmes most founders never hear about — and it is where the largest cheques are. Each domain now has a recognizable stack, from first grant to growth capital.
Space: a complete public capital ladder
Space is the template the other sectors are converging toward. An early-stage startup takes an IN-SPACe seed grant of up to ₹1 crore; the Technology Adoption Fund (₹500 crore corpus) then funds 60% of the cost of moving a technology from prototype to commercial deployment, up to ₹25 crore; the ₹1,000 crore space venture fund, managed by SIDBI Venture Capital, writes ₹10–60 crore equity tickets; and throughout, startups can license flight-proven ISRO technology at a 30% concession — 118 transfers done, including production of the SSLV launch vehicle itself.
SEED ₹1 CR · TAF ₹25 CR AT 60% · VC ₹10–60 CR · ISRO TECH AT −30%Defence: the biggest grant in the system
Beyond iDEX sits DRDO's Technology Development Fund: up to ₹50 crore per project, covering 90% of cost — the largest non-dilutive grant an Indian startup can access anywhere, open to DPIIT-recognized companies building against published defence technology requirements. Paired with ADITI's ₹25 crore challenges and Make-II's assured orders, defence is currently the deepest public funding stack in Indian deep tech.
TDF ₹50 CR AT 90% · NON-DILUTIVE · DPIIT STARTUPS ELIGIBLESemiconductors: design money and free tools
A fabless chip startup has two instruments. The Design Linked Incentive reimburses 50% of design expenditure up to ₹15 crore, then pays up to 6% of sales (capped at ₹30 crore) once chips ship — 24 design startups supported so far, with ISM 2.0 targeting fifty. Underneath it, the Chips to Startup programme and C-DAC's ChipIN Centre provide the industry-grade EDA tools — Synopsys, Cadence, Siemens — and subsidised tape-outs that would otherwise cost a startup crores a year; 95 startups already use them, and 254 chip designs have taped out.
DLI 50% ≤₹15 CR + SALES BONUS ≤₹30 CR · EDA ACCESS VIA CHIPINAI: compute as a subsidy
The IndiaAI compute portal has onboarded 38,000+ GPUs from fourteen providers, with H100-class rates discovered near ₹150 per GPU-hour and a subsidy of up to 40% for approved users — making the government effectively India's cheapest GPU broker. The foundation-model programme went further, pioneering compute-for-equity: Sarvam AI received thousands of H100s with the government taking a small stake via convertible debentures. AIKosha adds some 300 public datasets. For an AI startup, the mission's practical meaning is simple: your largest cost line is negotiable.
38,000+ GPUS · SUBSIDY ≤40% · DATASETS ON AIKOSHAQuantum: real cheques through the T-Hubs
The Quantum Mission runs a proper startup track through its four thematic hubs — IISc (computing), IIT Madras (communication), IIT Bombay (sensing), IIT Delhi (materials). A pre-VC startup can take seed funding up to ₹5 crore; a VC-backed one, up to ₹25 crore in equity — among the largest per-company instruments any science ministry operates. The call has been rolling since July 2025, decisions come within three months, and the guidelines' foreign-acquisition consent clauses say the quiet part aloud: India intends to keep its quantum companies.
SEED ≤₹5 CR · VC-BACKED ≤₹25 CR · ROLLING CALL · DECISION ≤3 MONTHSBiotech: the BIRAC escalator
Biotech is the one sector with a continuous public instrument chain: the ₹50 lakh BIG grant to ignite, SBIRI cost-sharing for early industry R&D, PACE for lab-to-market translation, LEAP equity of up to ₹1 crore through bioincubators, and the AcE fund of funds into biotech venture funds. BioE3 adds the infrastructure — six biofoundries and twenty-one bio-enabler facilities operational as of April 2026 — for pilot-scale biomanufacturing no startup could build alone.
BIG → SBIRI → PACE → LEAP → ACE · PLUS BIOFOUNDRY ACCESSEnergy: hydrogen pilots, and the nuclear opening
The Green Hydrogen Mission now funds startups directly: a ₹100 crore call gives up to ₹5 crore per pilot project for innovative production, storage, and utilization technologies — DPIIT startups under ten years old, majority Indian-owned, with milestone-based disbursement. India already counts some 249 hydrogen startups. In nuclear, the ₹20,000 crore SMR mission is still amending the laws that will let private companies participate — no startup instrument yet, but the direction is set, and the founders positioned when the Atomic Energy Act amendments pass will have a head start measured in years.
H2 PILOTS ≤₹5 CR · DPIIT <10 YRS · NUCLEAR OPENING IN PROGRESSTelecom: the fund behind the 6G speeches
The Telecom Technology Development Fund earmarks 5% of universal-service collections for telecom R&D — the only standing grant line in the sector open to startups, and the actual pipe through which Bharat 6G work is financed: 136 projects worth ₹542 crore approved, over a hundred of them in 5G/6G. Calls open roughly every six months; domestic ownership above 50% is required. For a telecom founder, TTDF plus the Bharat 6G Alliance's working groups is the whole game today.
136 PROJECTS · ₹542 CR APPROVED · CALLS EVERY ~6 MONTHSManufacturing: the ₹10 crore doorway
Most production-linked incentives are built for incumbents — the battery PLI's entry ticket exceeds ₹1,000 crore. The exception is the Electronics Components Manufacturing Scheme: its supply-chain segment carries a minimum investment of just ₹10 crore (with a 25% capital subsidy), is open until April 2027, and was topped up to ₹40,000 crore in the 2026 budget — genuinely reachable for a funded hardware startup. In medtech, the SMDI scheme offers capital subsidies capped at ₹10 crore for import-substituting components and, notably, the first central funding line for clinical validation studies of Indian devices.

Twelve missions. One frontier.
A mission is three things: a funding calendar, a testbed network, and a decade of demand.
Since 2015, India has stood up a national mission in nearly every deep technology domain. For a founder, a mission is three things: a source of funding calls, a network of centres and testbeds, and a signal of where the state intends to buy and build for a decade. Whichever sector you work in, its mission belongs on your watchlist.
Fabs, chip design and IP, and — in phase two — equipment and materials manufacturing. Design-linked incentives apply to startups, not only fabs.
Subsidized GPU compute, public datasets, and application funding — the compute programme is directly usable by startups.
Computing, communication, sensing, and materials — with a startup track of up to ₹25 crore per company.
Incentives for electrolyzer manufacturing and green hydrogen production, aimed at making India an export hub.
High-performance biomanufacturing — six biofoundries and twenty-one bio-enabler facilities operational by 2026.
R&D for small modular reactors — five indigenous SMRs targeted by 2033, with the sector opening to private participation.
Three-phase telecom R&D toward indigenous 6G, funded through TTDF; the Bharat 6G Alliance is the industry-facing door.
Submersibles, ocean-resource exploration, and blue-economy technology development.
Cyber-physical systems — robotics, autonomy, sensors — through Technology Innovation Hubs that run their own startup grants.
HPC access for researchers, MSMEs, and startups on the national grid.
Accelerating biopharmaceutical development, administered through BIRAC.
Securing the mineral supply chain beneath batteries, magnets, and clean energy — upstream of nearly every hardware venture.
Your first week.
Five actions, in order — none needs a warm intro, and the first is free.
- Get DPIIT recognition on the Startup India portal — free, online, and the eligibility key to nearly everything on this page. If your venture qualifies as deep tech, apply under the new category for the 20-year window.
- Find your sector stack in S–07 and bookmark its agency's calls page — TDF, TTDF, T-Hubs, DLI, or IN-SPACe. Funding calls are how these agencies speak; the founders who win are subscribed.
- Apply to one incubator in your domain's network (S–02) — PRAYAS, BioNEST, an Atal centre, or a Technology Innovation Hub. The grants flow through institutions; being inside one is the prerequisite.
- Register on GeM and link your DPIIT certificate — the turnover and experience exemptions only work for sellers who exist on the platform. If you're defence-adjacent, check the open iDEX challenges the same day.
- Ask your CA about 80-IAC and ESOP deferral before your next funding round or senior hire — both are elections you make, not defaults you receive.
