India deep tech interview: BYT Capital’s Amit Chand

India deep tech interview: how BYT Capital’s Amit Chand separates investable technology from promising research

India’s deep-tech ambition runs into a harder question: which parts of the stack can the country actually build today, and which still depend on imports? In this India deep tech interview, BYT Capital’s founder works through maturity, manufacturing constraints and the valley between research and a commercial product.

Amit Chand, Founder and Managing Partner

India’s deep-tech story is usually told in headlines — a new semiconductor fab, a quantum mission, a defence export — rather than in engineering. The harder and more useful question is where the country’s capability genuinely stops. A fund can name frontier sectors, but the work of investing in them is about maturity: which technologies are ready to be built into companies, and which are still research.

BYT Capital is a ₹180 crore, India-focused deep-tech venture fund that backs early-stage startups across semiconductors, quantum technologies, defence-tech, advanced materials, space tech, robotics and AI infrastructure. That sector list is also a list of engineering problems — fabrication, materials, precision manufacturing, supply chains — and this India deep tech interview is built around them rather than around the investment thesis.

The fund was founded by Amit Chand, its Founder and Managing Partner. He brings over 23 years of leadership experience spanning corporate strategy, entrepreneurship, design, product development and early-stage investing, and also serves as Managing Partner at BYT Avenue, an investor syndicate focused on deep tech and deep sciences. Readers will come away with a clearer view of where India’s frontier capability is real, where it is dependent on imported technology and global supply chains, and what separates a research result from a technology a company can actually be built on.

Maturity across the frontier

Q1. Across semiconductors, quantum, advanced materials, robotics, defence and space — which are technically mature enough in India to build a company on today, and which are still research?

AC: The more useful question is “which layer within a sector”. A company is buildable today if it can reach a convincing proof point within one funding cycle and has an identifiable first customer. By that measure, India’s list of buildable opportunities is longer than it has ever been. 

In semiconductors, chip design, specialised analogue, power and RF devices, and IP are all strong foundations for companies. In robotics, automation in structured environments such as inspection, welding and warehousing is commercially ready. Defence and space offer real opportunities across electronics, sensing, communications, satellite subsystems and Earth-observation data. Launch has joined that list now that a private Indian rocket has reached orbit. In advanced materials, coatings, composites, powders and thermal materials perform well when built against a named customer specification. In quantum, sensing, secure communication and the enabling hardware around them can support businesses today.

Some areas are on a longer horizon: leading-edge logic fabrication, fault-tolerant quantum computing, general-purpose humanoid autonomy, and materials still moving from gram to tonne scale. Here India is laying serious groundwork, through the Dholera fab, the National Quantum Mission and a growing research base.

The most exciting space may sit between the two: the instruments, components and processes that longer-horizon fields depend on. A company supplying cryogenics, precision optics or test equipment can build revenue today from the very programmes shaping tomorrow’s industries.

India’s Capability

Q2. Where does India’s capability genuinely stop today — which layers of the stack are still imported, and what would it take to close each one?

AC: India’s capability is uneven across the stack. We can have strong system-design expertise and still depend on a specialized imported component that determines the system’s ultimate performance. Recognizing those specific dependencies gives us a much more actionable development agenda. 

In semiconductors, important gaps sit in advanced fabrication, production equipment, electronic design tools and semiconductor-grade materials. Closing them requires sustained research, technology partnerships, manufacturing investment, and suppliers qualifying products in working facilities. In robotics, precision actuators, transmissions and sensors need deeper manufacturing capability and lifetime testing. In space, selected detectors, optics and high-reliability electronic components require specialized fabrication and extensive qualification. Quantum needs device fabrication to develop alongside control, measurement and supporting hardware. India’s semiconductor and quantum programs increasingly recognize these underlying requirements. 

Each gap needs a different response. Some can be addressed by startups; others require industrial partnerships, shared infrastructure or long-term national programs. The capital and development model must suit the problem. 

Our ambition should be to build depth where ownership creates technological and commercial advantage. India can participate confidently in global supply chains while developing critical capabilities at home—and creating specialized technologies that the rest of the world wants to buy. 

Manufacturing and supply chains

Q3. What are the hardest manufacturing and supply-chain constraints Indian deep-tech founders hit, and where do they remain structurally dependent on global supply chains?

AC: The most common challenge is scale. A startup needs fifty units of a precision part at production quality, while the best-placed supplier is set up for orders of five thousand. Resourceful founders handle this through small-batch partnerships, shared tooling, or building focused in-house capability that often becomes an advantage of its own. 

The second is consistency: delivering every batch to the same tolerance, and staying on top of any change in a supplier’s materials or process. Teams that bring in traceability and change control early move faster later. 

The third is access to test infrastructure such as environmental, vibration, thermal-vacuum and EMI testing. Capacity here is growing. For dual-use products, planning export-control licences early keeps imported components on schedule. 

The deeper dependencies are where global capacity is concentrated in a few places. Rare-earth magnets are the clearest example, and India’s new incentive scheme to build integrated domestic capacity shows how quickly policy is moving to address it. Specific sensors, semiconductor materials and manufacturing equipment follow a similar pattern, and each is an opportunity for Indian suppliers. 

The best founders treat supplier development as part of the product plan: engaging suppliers early, qualifying a second source in advance, and sharing demand forecasts. As more Indian hardware companies reach production, their combined demand is making specialist local suppliers viable, and that momentum is building.

Advanced Materials and Hardware

Q4. For advanced materials and hardware specifically, what does it actually take to build a domestic supply and fabrication base rather than assemble imported components?

AC: It requires control over the processes that create performance. In advanced materials, the chemical composition is only the starting point. Purity, particle size, microstructure, processing temperature and surface treatment can determine whether two apparently similar materials behave very differently. In hardware, comparable depth lies in component design, tooling, tolerances, packaging and testing. 

A domestic base therefore needs process engineers, reliable inputs, appropriate equipment and the measurement capability to understand why output varies. It also needs repeated production runs. Much of the valuable learning comes from identifying defects, correcting them and establishing a process that remains stable across batches and operators. 

The commercial side is equally important. A supplier needs customers willing to undertake qualification and offer sufficient visibility to justify investment. Shared pilot facilities can help bridge early development, while anchor customers can support the move towards dedicated capacity. Institutions such as ARCI already provide relevant pilot-scale development and technology-transfer capabilities. 

Localization becomes especially powerful when it enables joint development. A domestic supplier that understands the customer’s design can help improve performance, shorten iteration cycles and develop the next specification. That creates a much stronger foundation than a one-time substitution: it builds the capability to keep innovating and eventually serve international customers. 

Research to product

Q5. Where is the “valley of death” worst for Indian deep tech — between lab and pilot, or pilot and scale — and what fails there, technically?

AC: Both transitions matter, but for deep-tech companies, pilot to scale is often the more underestimated challenge. By then, the company has demonstrated enough to establish technical promise. The next step can look like increasing capacity, but it can introduce a new set of engineering problems. 

A larger materials reactor changes heat transfer and mixing. A coating that performs well on a small sample may become uneven across a larger surface. A robotic system that succeeds in a demonstration may reveal wear, thermal drift, or calibration issues during continuous operation. Variation between components and batches can reduce manufacturing yield – the proportion of output that meets specification – and weaken the economics. 

At the laboratory-to-pilot stage, the central question is often whether the effect survives outside carefully controlled conditions. At pilot-to-scale, the question becomes whether the company can deliver it reliably, repeatedly and economically. 

That distinction is encouraging because it makes the work more identifiable. Process instrumentation, reliability testing, manufacturing engineering, and customer qualification can address these challenges systematically. The strongest teams bring that thinking into development early. They use the pilot to understand the production process, including its limits, so that scaling becomes a progression built on evidence.

Investable Technology

Q6. In engineering terms, what separates a research result from an investable technology?

AC: An investable technology connects a demonstrated technical advantage with a credible path to customer value. It can still contain substantial development risk. The important question is whether that risk is understood well enough to be reduced through a disciplined engineering program. 

We look first at reproducibility: can the result be achieved across multiple samples, builds or operators? We then examine performance in the intended environment, integration into a complete system, reliability and the likely manufacturing process. System-level performance matters enormously. A device may be highly efficient in isolation, but its advantage can diminish once cooling, control electronics, calibration or packaging are included. 

We also ask whether the advantage is meaningful enough to support adoption. A customer may need to change a production line, qualify a new supplier, or accept operational risk. The improvement must justify that effort. 

At an early stage, we do not expect every answer to be available. We expect a clear account of what has been established, what remains uncertain, and which milestone the investment will finance. A strong opportunity lets technical progress translate into a stronger commercial position: a qualified sample, a successful field trial, or a product ready for a customer’s approval.

Technical defensibility

Q7. How do you assess technical defensibility in hardware and deep tech, where patents are weak and the real moat is tacit know-how and process?

AC: Patents can provide meaningful protection, particularly around an essential architecture, material, or manufacturing method. Their strength depends on what is protected, how easily competitors can design around it, and whether infringement can be detected. We assess them as part of a wider technical advantage. 

Execute on Deep Tech 

Q8. What signals tell you a team can actually execute on deep tech, versus having produced a good paper?

AC: A good paper can be an excellent starting point. Company building requires the team to carry that scientific understanding into a much broader set of decisions: what to build first, which specifications matter, how to manufacture it, and what a customer needs before buying. 

We learn a great deal from how founders discuss experiments that failed. Strong teams can explain the original hypothesis, the evidence that challenged it, and the change they made. They distinguish between a problem they understand and one they are still investigating. That clarity makes their development plans more credible. 

We also look for evidence of practical engagement: repeatable results across builds, disciplined test records, supplier conversations, realistic equipment and manufacturing estimates, and access to relevant testing facilities. Customer discussions should be specific enough to influence engineering choices. 

One of the best signals is a team that can explain what it has deliberately chosen to defer. Deep-tech founders face many technically interesting directions; execution requires concentrating resources on the product and milestones that matter first. 

We look for learning speed, engineering judgment, and the ability to attract complementary expertise. Those qualities help turn scientific ambition into a company that can deliver consistently. 

Capital intensity and timelines

Q9. Deep tech is capital-intensive with long development timelines. What does that mean for how a ₹180 crore fund is deployed, and how do you think about the timeline from technology to commercialisation?

AC: For a ₹180 crore fund, deployment starts with being clear about the stage of development we can finance. We focus on early-stage companies moving through technology validation, product qualification, customer adoption, and initial commercial scale, with typical investments of ₹3–7 crore and a portfolio of around 20 companies. 

Capital intensity varies considerably within deep tech. A specialized chip-design business, a robotics company and a new materials manufacturer can have very different infrastructure requirements. We examine how much capital is needed to reach a commercially meaningful milestone, what facilities partners can provide, and which capabilities the company must own. 

We also think about financing as a sequence. Research support, customer-funded development, strategic capital and later-stage investment can each play a role. Identifying those pathways early helps founders make better development and infrastructure decisions. 

Commercialization itself is a progression: a paid development program, a qualified product, an initial order and repeat production each establish something different. We evaluate timelines against that progression. 

Patient capital should give founders room to solve difficult problems while keeping expectations clear. Our job is to support ambitious engineering with disciplined milestones, appropriate follow-on capacity and the relationships needed to move from technical progress to sustained customer demand. 

Bottlenecks and what’s next

Q10. Which single technology bottleneck, if solved, would unlock the most in India’s deep-tech ecosystem — and where do you see the strongest emerging technical capability?

AC: Access to fabrication at pilot volumes. It matters across semiconductors, photonics, quantum devices, sensors and advanced materials. A team learns more from its twentieth consistent build than from its first working prototype: which parameters drive performance, where defects arise, and how yields can support a business. Making that learning faster and more accessible would speed up the whole ecosystem. 

India is making real progress here. The new quantum fabrication facilities at IIT Bombay and IISc Bengaluru, with additional facilities at IIT Delhi and IIT Kanpur, are a significant step. With predictable access, clear commercial and IP terms, and experienced process engineers, they could become a model for other device categories too. 

The strongest emerging capability, in our view, is complex systems integration in defence and space. India has an exceptional pool of engineers trained through ISRO, DRDO and the defence public sector, a large domestic anchor customer in defence procurement, and engineering economics that allow more iterations per rupee. Skyroot reaching orbit this year shows what Indian private teams can now deliver end to end. We expect similar breakthroughs in sensing, communications and autonomous platforms, and we’re excited to back the founders building them.

TechRecast Analysis (The Recast)

The Shift in Context

India’s deep-tech push has moved from aspiration to policy and capital: semiconductor incentives, quantum missions, defence indigenisation, a growing space sector. What has not moved as fast is the underlying engineering base — fabrication, materials, precision manufacturing. This India deep tech interview tests the gap between the ambition and the capability.

Why This Interview Matters

Deep-tech investing is easy to describe and hard to do, because the diligence is technical. The value of this interview is not the fund’s thesis but whether its principal can articulate, concretely, where India’s capability stops and what it takes to close the distance — sector by sector.

Technology Perspective

The questions that matter are about the stack. Fabrication and advanced materials sit beneath almost every frontier sector; robotics and defence depend on precision manufacturing; quantum and AI infrastructure depend on components India largely imports. The interview should press on which layers are genuinely buildable domestically and which are not yet.

Business and Market Perspective

A ₹180 crore fund is small relative to the capital intensity of fabs and advanced manufacturing, so its role is necessarily early-stage and selective. The commercial question is whether that size is a constraint or a discipline — and how it maps to the timelines deep-tech companies actually need.

Leadership Perspective

The relevant lens is the principal’s technical fluency. His operating background is in consumer, apparel and design, and his deep-tech mandate is newer; the interview should establish whether his sector knowledge is first-hand or relayed. That is a fair question for a fund positioning itself on research-driven technology.

The Counterpoint

A fair sceptic would argue that India’s deep-tech opportunity is real but the bottleneck is not capital — it is the supply of founders with deep technical experience and the domestic infrastructure to build hardware, neither of which a small fund can create. On this view, early-stage deep-tech funds risk funding good slides in sectors that need decades and billions. This is the strongest opposing case and deserves a direct answer.

What Comes Next

Watch three signals: whether the fund can name specific technologies it believes are buildable now, whether its portfolio companies reach pilot or production rather than staying in the lab, and whether the sectors it names move from imported dependence toward domestic capability over the next few years.

Industry Outlook

If the thesis holds, India’s deep-tech base broadens from software and applications into hardware, materials and manufacturing, and early-stage funds play a real role in seeding it. If it does not, the frontier stays a policy story, and capital flows back to software where returns are faster and nearer.

Key Takeaways

1. The useful deep-tech question is maturity — which technologies are buildable into companies now, and which are still research.

2. Fabrication, advanced materials and precision manufacturing sit beneath almost every frontier sector, and are India’s weakest layers.

3. The “valley of death” between research and a commercial product is where most deep-tech ventures fail, technically.

4. Technical defensibility in hardware rests on tacit know-how and process more than on patents.

5. A ₹180 crore fund is small against deep-tech capital intensity, which forces selectivity and an early-stage mandate.

6. The strongest counter-argument is that capital is not the binding constraint — technical founders and domestic infrastructure are.
