TLDR: Eight prominent venture capital and private equity firms from the U.S. and India have formed the ‘India Deep Tech Investment Alliance,’ committing over $1 billion in funding over the next decade. This initiative aims to bolster India’s deep tech startup ecosystem, focusing on critical sectors like AI, quantum computing, and semiconductors, and providing crucial long-term capital and mentorship.
In a significant boost for India’s burgeoning deep tech sector, a coalition of eight leading U.S. and Indian venture capital and private equity firms has announced the formation of the ‘India Deep Tech Investment Alliance’ (IDTA). This alliance has pledged to deploy over $1 billion in funding over the next five to ten years, targeting early-stage deep tech startups across India. The announcement, made by Celesta Capital’s founding managing partner Sriram Viswanathan at SEMICON India 2025 in New Delhi, underscores a concerted effort to address the historical underfunding and underappreciation of deep tech innovation in the country.
The alliance comprises well-known names in the venture capital landscape: Accel, Blume Ventures, Celesta Capital, Gaja Capital, Ideaspring Capital, Premji Invest, Tenacity Ventures, and Venture Catalysts. Their collective commitment extends beyond mere financial backing, encompassing mentorship, due diligence support, access to global and local networks, and market entry opportunities for portfolio companies.
The IDTA will focus its investments on a wide array of advanced technological fields, including semiconductors, space technology, quantum computing, robotics, artificial intelligence (AI), biotechnology, medical devices, and clean energy solutions. Initially, the semiconductor industry is slated to receive significant attention, as highlighted by IT minister Ashwini Vaishnaw.
This strategic move comes in the wake of earlier criticisms from Commerce Minister Piyush Goyal, who urged Indian startups to prioritize deeper innovation over consumer-focused applications. Many observers had pointed to a lack of patient, long-term capital as a primary impediment to deep tech growth in India. The IDTA directly aims to bridge this gap, promising the sustained capital and strategic support essential for companies requiring time and resilience to mature.
Furthermore, the alliance aligns with India’s broader economic and technological ambitions, connecting directly with the government’s ₹1 trillion (approximately $11 billion) Research, Development, and Innovation (RDI) scheme, announced in the 2024-25 national budget. The RDI scheme incentivizes locally incorporated startups, and the IDTA’s collaboration between U.S. and Indian VCs helps align with these policy goals.
Beyond economic implications, the formation of the IDTA carries geopolitical significance. It reinforces the ‘TRUST’ initiative, launched in early 2025 by the United States and India, aimed at strengthening technology collaboration between the two nations. This partnership demonstrates a shared long-term strategic value in advanced technologies, serving as a testament to both diplomatic and investment cooperation.

Sriram Vishwanathan of Celesta Capital emphasized the collaborative spirit, stating, “This is about energizing the ecosystem and bringing like-minded investors together.” He also indicated that the alliance is expected to expand, with more financial VC firms and corporates potentially joining in the future. The IDTA’s focus on seed to Series B investments signals a commitment to nurturing deep tech ventures from their foundational stages, fostering a robust ecosystem capable of producing globally competitive innovations.
