TDB kicks off RDI fund disbursal, backs startups across space, drones, biotech



The Technology Development Board (TDB), one of the two second-level fund managers for the Rs 1 lakh crore Research and Development Initiative (RDI) fund, has started disbursing the first tranche from its corpus.

TDB secretary Rajesh Kumar Pathak told ET that the board expects to disburse around Rs 500-600 crore during the current financial year. The first set of selected deeptech startups work across drones, spacetech, advanced batteries, and biotechnology.

Pathak added that TDB has selected 22 projects so far, including 14 startups, five MSMEs, and three listed companies. “Ticket sizes can be as low as Rs 3 crore and as high as Rs 100-150 crore, depending on the project,” he said.

The board has been allotted Rs 2,000 crore as patient capital to support deeptech firms and industry-led research within India. RDIF was announced by the central government in November 2025 with a corpus of Rs 1 lakh crore, to be deployed over six years, starting with an allocation of Rs 20,000 crore in FY26. The fund aims to operate through a two-tier structure with limited government intervention.

On Wednesday, Bengaluru-based iSTEM Research received Rs 50 crore for the development of indigenous cell therapies targeting two globally incurable diseases.

The first batch of selected companies includes EndureAir Systems for Project Subal 200, an indigenous unmanned helicopter platform capable of carrying payloads exceeding 200 kg for logistics, surveillance, and disaster response.
