For most of the last decade, the Indian startup conversation was dominated by consumer internet companies. Food delivery. Ride-hailing. Ed-tech. The businesses that scaled fastest were the ones that figured out how to acquire users cheaply and retain them through convenience. Very little of that was science. Almost none of it was hardware. And the few founders who tried to build on fundamental research spent years being told that India was not yet ready for deep tech.
That framing is now obsolete.
India has over 4,000 active deep tech startups, ranks sixth globally in the category, and raised $2.3 billion in deep tech funding in 2025, a 37% jump year-on-year. The government has deployed a ₹10,000 crore Deep Tech Fund of Funds. Eight leading US and Indian VC and PE firms announced a $1 billion India Deep Tech Investment Alliance at Semicon India 2025. IIT Bombay launched India’s first incubator-linked deep tech VC fund. The signals are converging in one direction.
What changed, what is being built, and what does any of this mean for founders and investors who want to understand this space without being overwhelmed by acronyms? Here is the breakdown.
What Deep Tech Actually Means
The term gets used loosely enough to be almost meaningless if you do not pin it down. Deep tech refers to startups whose core product is grounded in advanced scientific research or fundamental engineering innovation rather than a business model layer on top of existing platforms.
A food delivery app is not deep tech. A computer vision system that detects crop disease from a drone image is. A payments fintech is not deep tech. A semiconductor chip designed by an Indian team and fabricated domestically is. The distinction matters because the funding timelines, the talent requirements, the risk profile, and the investor base are all fundamentally different.
India’s deep tech universe spans artificial intelligence and machine learning, semiconductor design, space technology, quantum computing, robotics, biotechnology and synthetic biology, climate tech, and defence technology. Each of these has its own funding dynamics and its own relationship with the government. Understanding which sub-sector you are looking at is the first step to understanding the capital flows around it.
The Numbers: What the Funding Surge Looks Like
The trajectory is steep and recent.
Indian deep tech funding rose 78% in 2024 to approximately $1.6 billion, driven by a concentration of large rounds in AI and a handful of breakthrough companies across other categories. In the first four months of 2025 alone, deep tech investments hit $324 million across 35 deals, double the amount from the same period in 2024. By mid-2025, deep tech companies had raised $1.06 billion across 137 rounds, double the amount raised in the same period in 2024. Full year 2025 came in at $2.3 billion.
Cumulatively, Indian deep tech startups have raised $8.54 billion to date. That number puts the sector in a different conversation than it was in five years ago, when deep tech was discussed as an aspiration rather than an asset class.
The concentration problem is real, however. Money often concentrates in a handful of companies and cities, leaving many early teams underfunded. Bengaluru accounts for the largest share, and the capital available at pre-seed and seed for deep tech founders outside the IIT and IISc networks remains thin relative to the talent that exists.
The Categories Drawing the Most Capital
AI is the dominant story. Among deep tech investments in 2024, 87% flowed into AI-based startups, with 450 new deep tech firms founded that year. In 2025, AI’s share rose further, with AI alone accounting for 91% of all deep tech funding by some estimates.
Sarvam AI is the clearest proof point. Founded to build multilingual large language models for India, it raised a $41 million Series A and was subsequently selected by the central government to build India’s first homegrown sovereign LLM under the IndiaAI Mission, a programme with a ₹10,300 crore budget over five years. The IndiaAI Mission’s emphasis on sovereign AI infrastructure is creating a class of government-backed deep tech companies that did not exist before 2023.
Semiconductors are the strategic bet. The Semicon India Programme, launched in 2021 with incentives and collaborative infrastructure for fabless chip design, has supported 23 startups through the Design Linked Incentive scheme as of early 2026. India’s first indigenous semiconductor chip was announced for production in 2025. The talent to design chips exists in India because the same engineers who built chips for Intel, Qualcomm, and AMD in Bengaluru and Hyderabad over the last two decades are now available as founders, advisors, and early employees.
Space technology had a difficult 2024, with funding dipping 55% to roughly $59 million from $130 million in 2023. The correction reflected investor caution after a period of enthusiasm, but government support has continued. IN-SPACe, the Indian National Space Promotion and Authorisation Centre, has opened ISRO’s facilities to private startups in a structural shift that would have seemed impossible a decade ago. Digantara, focused on space domain awareness, and Pixxel, building a hyperspectral satellite constellation, are among the funded names in this category.
Biotech and climate tech are earlier stage but attracting sustained attention. The Bio-E3 Policy is being implemented to promote biotechnology entrepreneurship and biomanufacturing. Varaha, working on carbon credits through enhanced rock weathering, achieved Asia’s first such carbon credit issuance with Puro.earth in 2025 and is in talks for a Series B.
The Government’s Role: Bigger Than Most Founders Realise
The Indian government’s involvement in deep tech funding is not incidental. It is structural and growing.
The Startup India Fund of Funds 2.0, with a ₹10,000 crore corpus approved in the 2025 Union Budget, operates as a fund of funds, committing government capital to private alternative investment funds that will then invest in startups. It specifically emphasises geographic expansion beyond metros and support for smaller domestic VC firms. India has also doubled the startup classification period for deep tech firms to 20 years and raised the revenue threshold for benefits to ₹300 crore, recognising that deep tech companies take longer to generate revenue than consumer internet businesses.
The Research, Development and Innovation Fund has a corpus of ₹1 lakh crore to strengthen innovation capabilities across the ecosystem. IIT Bombay’s SINE launched the Y-Point Venture Capital Fund with a ₹250 crore corpus to back pre-seed and seed stage companies from IIT Bombay and other leading research institutions, with investments of up to ₹15 crore each.
This level of public capital commitment signals something important: the government has decided that technological self-reliance in AI, semiconductors, space, and biotech is a strategic priority, not just an aspiration. Founders who understand how to operate within this environment, accessing government grants and incentives without becoming dependent on them, have a structural advantage.
What Global Deep Tech Tells Indian Investors
The 30% global reference point here is both encouraging and sobering.
Indian deep tech startups raised $1.65 billion in 2025, a sharp rebound, but still a fraction of the $147 billion deployed in the US deep tech sector in the same period. The EU’s deep tech startups attracted €15.1 billion in venture capital in 2024. Israel, with a population smaller than Maharashtra, has built a globally known deep tech ecosystem in cybersecurity and biotechnology through the Yozma programme of public-private partnership.
The gap is not primarily about talent. India has world-class engineers and scientists. It is about patient capital, which is capital willing to wait ten years for a semiconductor company to go from design to commercial production, and about the institutional mechanisms that allow research from universities to become investable companies. Both are improving but neither is yet at the level required to produce globally competitive deep tech companies at scale.
Eight US and Indian VC and PE firms, including Accel and Blume Ventures among others, announced a $1 billion India Deep Tech Investment Alliance at Semicon India 2025, with a focus on AI, semiconductors, robotics, biotech, and climate tech. This kind of US-India collaboration in capital is a meaningful signal that global investors are beginning to treat India as a credible deep tech destination, not just a software services hub.
What Founders Building in Deep Tech Need to Know
The first thing is that the timelines are non-negotiable. A SaaS startup can iterate weekly and show meaningful metrics in six months. A semiconductor design startup has a chip tape-out cycle measured in years. A biotech startup has clinical validation requirements that do not compress regardless of how good the engineering is. Founders who understand this going in plan their capital raises, team structures, and milestone definitions accordingly. Founders who do not run out of runway mid-development.
The second is that IP matters enormously. Over half of India’s deep tech ventures originate from academic environments. The relationship between the founding team and the IP developed at an institution, who owns it, how it is licensed, and whether it is exclusive, is often the first thing a serious investor will investigate. Founders who have not resolved their IP situation before approaching investors will find the conversation stalling before it begins.
The third is that the government is a stakeholder whether you engage with it or not. Regulatory frameworks for drones, satellites, biotech products, and AI systems are all evolving in India. Building without tracking regulatory developments is a risk that compounds over time.
The Take Nobody Will Say Out Loud
The deep tech funding surge in India is real. The strategic intent behind it, from both government and investors, is genuine. What is not yet clear is whether the capital is reaching the founders who are building the hardest things, or whether it is clustering around the companies that are easiest to understand and fund.
AI is getting 87 to 91% of deep tech funding, which makes sense because AI companies are easier to evaluate, produce revenue faster, and have reference points in the US that investors can anchor to. But semiconductors, quantum computing, advanced materials, and synthetic biology require a different kind of capital. They require investors who can read a technical paper, evaluate IP claims, and wait a decade for a return. Very few Indian VCs have built that capability yet.
The founders building in those harder categories are doing something important. They are the ones whose work will actually determine whether India can become technologically independent in the ways the government says it wants to be. They deserve more capital than they are currently getting, and they deserve investors who understand what they are building rather than investors who are backing deep tech because it is the narrative of the moment.
The next five years will reveal whether the capital flowing into Indian deep tech is patient enough to survive the timelines the science demands. That answer will determine whether India produces globally competitive deep tech companies or another generation of well-funded startups that ran out of runway before the research became a product.
Frequently Asked Questions
What is deep tech and how is it different from regular tech startups? Deep tech startups build products grounded in advanced scientific research or fundamental engineering innovation, such as AI systems, semiconductor chips, biotech compounds, quantum hardware, and space technology. Regular tech startups typically build software or digital platforms on top of existing technology. Deep tech requires longer development timelines, more R&D investment, specialised talent, and patient capital willing to wait years before commercial revenue begins.
How much funding have Indian deep tech startups raised? Indian deep tech startups raised approximately $2.3 billion in 2025, up 37% from 2024’s $1.6 billion, which itself was a 78% jump from 2023. Cumulatively, Indian deep tech companies have raised $8.54 billion to date. In early 2025, the pace doubled compared to the same period in 2024, with $324 million raised in just the first four months.
Which deep tech sectors are attracting the most funding in India? AI and machine learning dominate, accounting for 87 to 91% of all deep tech funding in recent years. Semiconductors are a growing priority driven by government incentives under the Semicon India Programme. Space technology, biotech, climate tech, and robotics are earlier stage but attracting sustained investor and government interest. Quantum computing is nascent but receiving institutional support through India’s National Quantum Mission with a ₹6,000 crore budget.
What is the Indian government doing to support deep tech startups? The government has deployed several major initiatives. The Startup India Fund of Funds 2.0 has a ₹10,000 crore corpus focused on deep tech and advanced manufacturing. The IndiaAI Mission has a ₹10,300 crore budget over five years. The Research, Development and Innovation Fund carries a ₹1 lakh crore corpus. The startup classification period for deep tech firms has been doubled to 20 years, acknowledging their longer development timelines.
What are the biggest challenges for deep tech founders in India? The three most significant challenges are the shortage of deep tech-literate investors who can evaluate technical IP and wait for long development cycles, the gap between academic research and commercial application, which requires structured IP licensing and industry-academia collaboration, and geographic concentration of capital in Bengaluru and a handful of elite institutions, leaving founders outside that network significantly underfunded.
Who are the notable Indian deep tech startups to watch? Sarvam AI is building India’s sovereign LLM under the IndiaAI Mission. Pixxel is building a hyperspectral satellite constellation. Digantara focuses on space domain awareness. Varaha works on carbon credits through enhanced rock weathering. QpiAI operates at the intersection of AI and quantum computing. Netradyne builds AI-powered solutions for logistics and fleet safety. These names represent a range of sub-sectors and funding stages across the deep tech spectrum.
How does India’s deep tech funding compare to global benchmarks? India raised $2.3 billion in deep tech funding in 2025, compared to approximately $147 billion deployed in the US deep tech sector in the same period. The EU attracted over €15 billion in deep tech VC in 2024. The gap reflects both the relative youth of India’s deep tech investor base and the historical concentration of Indian startup capital in consumer internet rather than science-driven ventures. The gap is narrowing, but significant ground remains to be covered.
