US-India VCs Unleash $1 Billion for India's Deep Tech, AI Startups
Beyond capital, this $1B U.S.-India alliance will address systemic underfunding, nurturing India's next-gen deep tech giants.
September 3, 2025

A coalition of prominent U.S. and Indian venture capital firms has formally launched the India Deep Tech Investment Alliance (IDTA), committing over $1 billion to catalyze growth in India's burgeoning deep technology sector. Led by Celesta Capital, the alliance includes venture capital and private equity firms Accel, Blume Ventures, Gaja Capital, Ideaspring Capital, Premji Invest, Tenacity Ventures, and Venture Catalysts.[1][2][3] This significant capital injection is earmarked for early-stage Indian startups, specifically from seed to Series B rounds, aiming to address a critical funding gap and build globally competitive companies in foundational technologies.[4] The initiative represents an unusual level of collaboration among typically competitive investment firms, signaling a unified belief in the strategic importance of India's deep tech landscape.[5] The alliance will focus on startups in critical and emerging fields such as artificial intelligence, semiconductors, space technology, quantum computing, robotics, biotech, energy, and climate tech.[2][4]
The formation of the IDTA is strategically timed to complement and leverage a major policy push from the Indian government. It directly aligns with the recently approved Research, Development, and Innovation (RDI) Scheme, a government initiative set to deploy ₹1 lakh crore (approximately $12 billion) to foster research and innovation within strategic sectors.[1][3] By focusing on Indian-domiciled startups, the alliance ensures its portfolio companies can benefit from government incentives under programs like the RDI scheme.[6][5] This public-private synergy is designed to create a robust ecosystem for deep tech innovation, combining government support with private capital and global expertise. Sriram Viswanathan, Founding Managing Partner at Celesta Capital, highlighted this connection, stating, “With the catalytic support mobilized under the RDI Scheme, this is a historic opportunity to deepen U.S. - India partnership and power the next wave of transformative global companies.”[1] The alliance will also serve as a unified voice for engaging with policymakers on regulatory matters that affect the startup environment.[2]
A primary motivation for the alliance is to rectify the systemic underfunding that has historically hindered India's deep tech startups. Despite possessing a vast pool of engineering talent, India's deep tech sector has struggled to attract patient capital, which is essential for the long development cycles and significant research and development costs inherent in these fields.[2][4] In 2023, deep tech ventures received just 5% of the total startup funding in India, a figure that pales in comparison to the 35% allocated in China.[2][4] This scarcity of funding has been a point of concern, with Indian Commerce Minister Piyush Goyal previously noting a tendency for startups to focus on consumer services rather than foundational technologies.[6] The IDTA aims to directly address this challenge by providing not just capital, but also intensive mentorship, global network access, and support for market expansion, particularly within the U.S.-India corridor.[1][6]
The implications of this billion-dollar alliance for the global technology landscape, and particularly the AI industry, are substantial. By fostering innovation in areas like semiconductors and artificial intelligence, the IDTA is positioned to strengthen India's role as a creator of critical technologies, moving beyond its established reputation as a service provider.[4] For the AI sector, this means a potential surge in new hardware and software solutions emerging from India, addressing global needs. The focus on the U.S.-India corridor is designed to create a symbiotic relationship, where Indian startups gain access to global markets and U.S. firms can leverage India's manufacturing and talent base.[1][7] The alliance, chaired initially by Celesta Capital Managing Partner Arun Kumar, will be governed by an advisory committee to coordinate its objectives while allowing each member fund to operate independently.[6][8] This long-term, thesis-driven investment approach, spanning five to ten years, underscores a commitment to building a sustainable and globally impactful deep tech ecosystem from India.[1][5]
