IDTA members deployed ₹2,170 crore across 56 deep-tech startups, with energy, quantum, robotics and AI among the key sectors funded.
NEW DELHI: The India Deep Tech Alliance (IDTA) disclosed on September 18, 2026 that its member investors deployed approximately ₹2,170 crore across 56 India-incorporated deep-technology startups over the alliance’s first full year of operation, spanning September 1, 2025 to August 31, 2026. The announcement came on the second day of SEMICON India 2026 in New Delhi, marking the first concrete execution milestone since the consortium launched with a pledge exceeding $1 billion a year earlier.
Unlike a traditional venture fund, IDTA holds no pooled capital and manages no single investment vehicle. The ₹2,170 crore figure is instead an aggregate of independent deployments made by individual member firms under their own investment mandates, coordinated through shared technical diligence rather than joint decision-making. Sriram Viswanathan, an IDTA executive committee member and founding managing partner at Celesta Capital, said the sum invested across more than 50 companies shows the alliance’s founding vision beginning to translate into measurable action.
Why Deep Tech Needed Its Own Alliance
IDTA emerged from a specific structural gap in Indian venture capital. Between 2012 and 2021, domestic VC overwhelmingly backed consumer internet platforms, e-commerce and enterprise software, businesses with low technical risk and fast paths to revenue. Hard-tech sectors such as semiconductor design, quantum computing, synthetic biology and advanced robotics demand patient capital, deep domain expertise and tolerance for long gestation periods, qualities that generalist venture funds have historically found difficult to underwrite alone.
To address this, IDTA brought together 24 venture capital firms, including Accel, Blume Ventures, Chiratae Ventures, Kalaari Capital and Premji Invest, alongside seven corporate and strategic members including NVIDIA, Applied Materials, Micron Technology and Larsen & Toubro. The alliance is chaired by Arun Kumar of Celesta Capital, with Arvind Mathur, former head of the Indian Venture and Alternate Capital Association, serving as chief executive. Rather than pooling money, the consortium operates through shared pipeline access, technical co-diligence on complex hardware and biology bets, and coordinated syndication among members.
Where the Capital Actually Went
The deployment mapped cleanly onto the five priority sectors of the government’s Research, Development and Innovation Scheme. Energy security, transition and climate technologies absorbed the largest share at ₹655 crore across just 8 companies, producing the portfolio’s highest average ticket size of nearly ₹82 crore per startup, reflecting the heavy capital needs of battery chemistry validation and pilot manufacturing lines. Deep technology, spanning quantum computing, robotics, space and defence systems, received ₹649 crore spread across 21 companies, while artificial intelligence applications drew ₹639 crore across 16 companies. Biotechnology and biomanufacturing rounded out the portfolio with ₹189 crore across 7 companies and digital economy and agritech ventures received a comparatively modest ₹38 crore across 4 companies.
Notably, IDTA has not published an itemised list of the 56 recipient companies, nor disclosed valuation metrics, dilution percentages or the extent of co-investment overlap among its members. This leaves the sectoral totals as the primary lens through which outside observers can assess the deployment.
The Policy Backdrop
IDTA’s first-year execution overlaps with a broader government push to de-risk private deep-tech investment. The Union Cabinet approved a ₹1,00,000 crore Research, Development and Innovation Scheme in July 2025, offering long-term concessional financing to private entities working at Technology Readiness Levels 4 and above. Separately, at the same SEMICON India 2026 event, Union Minister Ashwini Vaishnaw unveiled “Semicon 2.0,” expanding the government’s semiconductor design target to 200 startups, up from 105 in the scheme’s first phase. IDTA also announced a partnership with global body SEMI to launch the India Semiconductor Academy, aimed at building the engineering talent pipeline the sector will eventually need.
Prof Ajay Kumar Sood, Principal Scientific Adviser to the Government of India, described the alignment between IDTA’s sector focus and the RDI Scheme’s priority areas as an encouraging signal of growing private-sector confidence in India’s innovation ecosystem.
A Modest Number by Global Standards
Set against global deep-tech financing, however, ₹2,170 crore, or roughly $260 million, remains a relatively small sum. In the United States, Western Europe and East Asia, single Series B or C rounds for foundational AI models or quantum hardware companies routinely exceed $100 million to $500 million each. IDTA’s average allocation of ₹38.75 crore, or about $4.65 million per startup, suggests the capital is functioning primarily as seed or early Series A funding, useful for prototyping and lab-to-fab translation, but insufficient on its own to build commercial-scale semiconductor equipment or high-throughput biomanufacturing facilities.
That gap raises the central question hanging over the alliance’s next phase: whether member funds will maintain dedicated growth-stage reserves as these 56 companies mature, or whether they will need global crossover funds to step in for larger follow-on rounds. Equally unresolved is how many of these ventures will successfully advance from lab validation to full commercial production, how smoothly private equity will blend with the RDI Scheme’s concessional debt lines, and what exit pathways exist for capital-intensive hardware and biotech companies given India’s public markets’ historical preference for profitable, revenue-stable businesses.
For now, the ₹2,170 crore figure stands as a proof of concept that India’s venture ecosystem is beginning to underwrite hard-tech risk collectively. Whether it scales into the hundreds of crores per company that global deep-tech competition demands will depend on decisions IDTA’s members have yet to make public.
