Private participation is reshaping India's space sector. Evaluate the role of state-backed financing institutions such as the Technology Development Board in this transition.

The Technology Development Board (TDB) is a statutory body set up under the TDB Act, 1995. It finances firms that develop indigenous technology [1]. It now manages money under the ₹1 lakh crore RDI Scheme [2], which makes it a funder of private space start-ups. Its role is a necessary one, but it is not yet complete.

Positive role

• Bridging the "valley of death": TDB gave Manastu Space ₹116 crore to take a green propulsion system from TRL-6 to TRL-9 [3]. Private investors rarely fund that long stretch of flight qualification.
• Shared risk, not charity: loans are collateral-free but capped at 50% of project cost [4]. Manastu's ₹116 crore is about 42% of a ₹277.63 crore project [3]. The scheme gives no grants, so repaid money can be lent again [5].
• Strategic indigenisation: green propellants replace toxic hydrazine and cut reliance on foreign technology [3]. TDB also gave ₹200 crore to Agnikul for a reusable launch vehicle [6].
• Building on ISRO's platforms: start-up thrusters first flew on ISRO's POEM-4 [7]. TDB money helps them move from a test flight to a product.

Limitations

• Fiscal exposure: unsecured loans and Optionally Convertible Debt leave little to recover if a firm fails [3][4].
• Approvals ahead of cash: TDB has approved ₹2,192 crore for 22 projects. Only ₹500 crore had reached it by March 2026 [5]. Late releases could stall milestone payments.
• Bottleneck: so far TDB and BIRAC are the only fund managers [5], so most non-biotech deep-tech money passes through one body.
• Picking winners: Bellatrix and Manastu both flew rival hydrogen-peroxide thrusters on POEM-4 [7]. Backing one firm can shape the market unless all rivals get equal access.
• No buyer, no TRL-9: finance cannot replace a first customer. A thruster reaches TRL-9 only by flying on real missions.

Verdict and way forward TDB is moving public R&D support from grants to patient capital, and this suits the long gestation of space technology. To make it fully effective, the government should:

• release funds on a planned schedule that matches approvals;
• link each payment to a published milestone;
• appoint more fund managers;
• have ISRO and IN-SPACe act as anchor customers.

With these steps, state finance can grow a competitive, self-reliant space industry, in line with Atmanirbhar Bharat and SDG-9.
