India’s TDB halts R&D funding call amid review backlog

The move comes as the board works through a backlog of proposals—73 still under review as of April 2026—after approving 22 out of 124 submissions since the scheme’s launch. The closure, which TDB has not linked to a funding shortage, highlights the difficulties of managing a high volume of applications in sectors where capital is often limited.

TDB’s pipeline shows a surge in interest. The board received 35 proposals in February, 62 in March, and 27 in April, suggesting demand that may have outpaced its review capacity. The 22 approved projects, as previously reported, involved combined R&D costs that stood out in the Indian funding landscape. The backlog of 73 proposals could indicate a system struggling to keep up with demand.

The timing coincides with a period of strong private investment in India’s deep tech sector. Pixxel’s $100 million Series C, the country’s largest space-tech round, closed just days before TDB’s funding call shut. TDB’s scheme was designed to address this gap, but its current pause may leave some projects in limbo.

The board’s statement offers few details. “Administrative reasons” could involve internal delays, procedural changes, or other logistical issues. The pattern, however, suggests a potential bottleneck. Similar government-backed funds elsewhere, such as DTCP’s €455 million defence-tech fund or Belgium’s WAD Capital debut, have moved at different speeds, often with input from institutional or strategic investors. TDB’s process, by comparison, may face unique challenges.

For now, the 73 proposals under review remain in an uncertain position. If the board’s pace doesn’t improve, some projects could face prolonged delays. Founders in competitive sectors may find themselves at a disadvantage, as time lost in review could affect their ability to compete globally.

The closure raises questions about India’s approach to funding deep tech innovation. The government has emphasized goals like reducing reliance on foreign technology, particularly in defence, semiconductors, and space. TDB’s funding call was one way to advance these objectives, but its current pause creates a gap. Private investors may fill some of this space, but likely only for projects that are already de-risked.

What happens next will depend on how quickly TDB resolves its backlog. If the call reopens soon, the impact may be minimal. If it remains closed, India’s deep tech ecosystem could face a period of reduced support just as it seeks to expand.
