Robotics, chips and other deep tech in India, explained

What falls under this area?

This area brings together hardware-led and science-led startups. Robotics covers machines that move and work on their own, such as ANSCER Robotics, which builds autonomous robots for factories. Chips cover the design and making of semiconductors, and also the electronics around them. SEDEMAC designs and makes electronic control systems. Drones and defence are served by firms such as Flying Wedge Defence & Aerospace, an Indian drone maker.

Space is another strand. Skyroot Aerospace builds rockets, TakeMe2Space works on orbital computing, and recent headlines in the StopDown data include Astrogate Labs tying up with Spacebeam on laser links. Quantum computing is also here: Quanfluence raised $10M for a photonic quantum computer, a machine that uses light to compute.

What these have in common is that a physical prototype must work before sales can begin, and a failure costs real time and money.

Why is it hard and slow?

A software team can release a fix in an hour. A hardware team must design, build, test, certify and manufacture, and each loop takes weeks or months. A rocket test or a chip tape-out (the point when a design is sent for manufacture) is expensive and cannot be undone.

Supply chains add difficulty. Many components, especially advanced chips, are imported, and lead times are long. Testing labs, clean rooms and skilled technicians are limited in India, though more are being built.

Because of this, deep tech founders often come from research or defence backgrounds, raise money in stages tied to technical milestones, and take longer to reach profit than app companies.

Manufacturing know-how is its own bottleneck. Making ten units by hand is very different from making ten thousand with steady quality, and many hardware startups stall at that step. Partnerships with contract manufacturers, and access to shared testing facilities, can shorten the road.

How do these startups make money?

Revenue sources vary. Robot makers sell machines or rent them as a service. Component makers sell to other manufacturers and wait for a design to enter a customer's product. Drone makers sell to defence, agriculture and surveying customers, often through government tenders. Launch and satellite firms sell launches, data or services to government and commercial customers.

Early income often comes from non-sale sources: research grants, development contracts, pilots with large companies and government programmes. This helps pay for the long build period but can create dependence on a single buyer.

Chip design firms may earn from licensing designs or selling chips in volume, while chip fabs and packaging units earn by manufacturing for others, a business that needs very large investment and steady orders.

Because sales are lumpy, one large order can change a year. Readers should be careful about announcements of memorandums of understanding, which are statements of intent and not firm orders.

What does it cost and who funds it?

Cost is mainly capital equipment, prototypes, specialist staff and testing. Equity from venture funds is common, and in the last 12 months the StopDown data shows names such as Peak XV Partners, Accel, Lightspeed, Khosla Ventures and Nvidia active in AI and deep tech. India Accelerator appears among early-stage backers.

The government funds a large share indirectly. The India Semiconductor Mission supports fabs and packaging units; as of July 2026 twelve units were approved under its first phase, and the Cabinet approved a second phase, Semicon 2.0, in July 2026, although reports differ on its size and incentive rates. The IndiaAI Mission gives subsidised GPUs. Drone makers have a production-linked incentive scheme, and IN-SPACe supports private space firms.

Founders also use bank loans, venture debt and customer pre-payments to avoid giving up too much ownership.

What rules and risks apply?

Each strand has its own rules. Drones follow the Drone Rules, 2021, which cover registration, certification and where and how they can fly. Space activity needs authorisation through IN-SPACe. Wireless and telecom equipment need approvals, defence supply follows procurement rules, and chip units must meet environmental and safety standards. Products that collect data also fall under the DPDP Act, 2023.

Key risks are technical failure, long timelines, cash running out before a product is proven, import dependence, and reliance on a single government customer whose budget or policy can shift. Global rivals with deeper funding are another pressure.

Rules and schemes change, and this is general information, not legal advice. Check current requirements with a professional before building or launching.

How do you judge a deep tech company?

Look at milestones, not just revenue. Has the team shown a working prototype, passed a key test or won a first paying order? Funding in this area is released in steps, and each step should match a clear technical result.

Check the supply chain and certification path. Which parts are imported, how long do they take to arrive, and which approvals does the product need before it can be sold or flown? Ask who the first customers are and whether they depend on a single government department.

Look at the team too. Deep tech teams often combine researchers, who know the science, with operators, who know how to build and ship. A strong mix reduces the risk of a clever prototype that never becomes a product.

What is changing next?

Government support is widening: a second phase of the semiconductor mission, subsidised AI computing and open private access to space are all in place or in progress. More private capital is also arriving, with names such as Nvidia and India Accelerator seen in recent AI and deep tech rounds. The test is whether these companies move from prototypes to repeat orders, since that is what turns a promising technology into a lasting business.

The breakdown

Business models

The numbers that matter

• Time to first revenue can be years, so funding is staged against technical milestones.
• Capital intensity is high: equipment, labs and prototypes are needed before volume sales.
• Unit cost falls with volume, so reaching scale is central to margins.
• Government schemes can cover a large share of cost for chips and drones, but approvals take time.

Rules and regulators

Risks

• Technical failure in tests or launches.
• Long build times and cash running out first.
• Dependence on imported components.
• Reliance on a few government buyers.
• Competition from better-funded global firms.
