Purus Research is a principal investment firm committing the proprietary capital of its founding principals to early stage critical and emerging technology companies in India, across venture and listed markets. The firm is founded on a geoindustrial thesis, which holds that technology sovereignty, supply-chain resilience, and economic statecraft now determine the transformational reach of frontier science as decisively as first-of-kind intellectual property embedded in hardware, physics, chemistry, biology, and advanced materials, or as the engineering complexity that itself constitutes the moat.
Integrating Indian national-security and geoeconomic analysis with exacting technical and financial diligence, Purus backs founders who convert India's scientific talent and free enterprise into compounding sovereign capability.
Six domains where scientific discovery and cumulative process learning compound into industrial diffusion, making sovereign capability affordable rather than subsidised
Reconfigurable and open-ISA silicon,
immune to instruction-set leverage
A breakthrough at the level of physics, chemistry or biology alters the production function of an entire industry. Capability of this order is defended by the cumulative process knowledge required to reproduce it, and it is increasingly governed by states through export control regimes, licensing chokepoints and restrictions on the transfer of process technology itself. India, approaching the position of third largest economy, is arriving at scientific maturity in the same period in which these instruments of technological containment are proliferating, so the capacity to build such technologies domestically has become a determinant of national security prior to any consideration of return.
The economics of a frontier technology cannot be read apart from the science that sets its cost curve, and the science cannot be read apart from the states that decide where it may be built and to whom it may be sold. Purus therefore assesses science, engineering and geoeconomics in a single act of judgement, not in sequence, and commits proprietary capital where that judgement finds Indian founders turning discovery into capability the country would otherwise import on another power's terms.
Purus underwrites a frontier technology for whether the science is real and reproducible, then for whether the capability can be built in India under the dependencies, controls, and sovereign demand that govern it.
Design holds over half a chip’s value, and a fifth of the world’s designers are Indian. Sixteen tape-outs and 140 domestic IP cores have since followed.
Cell therapy made here treats at ₹30 lakh against imported crores. Turbine magnets are ninety percent imported, though India’s rare earth reserves rank third. Deep tech costs fall with cumulative volume, which makes a market of India’s size a manufacturing instrument, and technologies proved at Indian prices become affordable to countries that would otherwise go without them.

Purus Research is a principal investment firm deploying proprietary capital into early-stage critical and emerging technology startups in India and Southeast Asia.
The firm pursues integrated theses linking frontier technological capability, industrial and manufacturing feasibility, Indian strategic context, and wider market dynamics across both private ventures and public markets, with an emerging proprietary intelligence and diligence capability as its central source of competitive edge.
India reached Mars orbit on its first attempt and soft-landed at the unexplored lunar south pole on budgets a fraction of comparable Western programmes, and since 2020 the sector has opened to private capital with FDI permitted up to 100% in satellite components. Purus backs early-stage deep tech founders building the frontier of this opening, from reusable launch propulsion and small-satellite constellations to in-space propulsion, orbital docking, and space-based earth observation analytics. What draws us in is that India's institutional heritage has already proven the capability while the commercial layer remains young, and the ventures that will industrialise frugal engineering into globally competitive launch and orbital infrastructure are being founded right now.
India holds close to a fifth of the world's semiconductor design workforce yet fabricates almost none of its own chips, importing the overwhelming majority of what it consumes even as domestic demand races toward roughly $100 billion by 2030. Purus invests in startups working at the hard end of converting that design depth into silicon, from fabless chip design and custom RISC-V architectures that escape foreign licensing, to compound semiconductors such as gallium nitride and silicon carbide for defence, radar, and power electronics, to edge AI processors and next-generation packaging. We are convinced that design talent alone confers no sovereignty, and that the founders moving India from concept to shipped silicon, owning the architectures and compound-material capability the country still imports, will decide whether strategic dependency hardens or breaks this decade.
India remains the world's second-largest arms importer, and the recent decline in that dependency owes partly to a deliberate national push toward indigenous production and supply-chain sovereignty in defence. Purus backs deep tech startups across the dual-use frontier, from AI-enabled autonomous and swarming uncrewed systems, loitering munitions, and counter-drone interceptors, to electronic warfare, secure communications, and networked C4ISR, to advanced electro-optical sensing, ISR, and underwater and maritime autonomy. For us the pull is that indigenisation here answers a sovereign necessity rather than a procurement preference, and with autonomy and embedded AI now defining the modern battlefield, the early-stage ventures closing these capability gaps carry commercial scale and national consequence at once.
India supplies roughly a fifth of the world's generic medicines by volume and about 60% of its vaccines, yet ranks only fourteenth by pharmaceutical value and stays critically dependent on China for the active ingredients behind its most important drugs. Purus invests in founders pushing into the higher-value science, from indigenous cell and gene therapies and domestic biologics to AI-driven drug discovery, synthetic biology, and precision fermentation and biomanufacturing that substitute imported inputs. We are drawn to a deeper edge that is uniquely India's, namely the proprietary biological datasets drawn from a population long underrepresented in global discovery pipelines, since the founders who build predictive models on that foundation create a moat no amount of compute can replicate, and the next phase of growth will be powered by that scientific ownership rather than manufacturing volume.
India carries 100% import dependency on lithium, cobalt, and nickel, while China controls roughly 91% of global rare-earth processing and 70% of refined lithium, which makes materials a binding constraint on every transition built above them. Purus backs early-stage ventures in the technically hardest layer, from recycling and urban mining that turn e-waste into rare-earth magnets, to green extraction and the refining capability India almost entirely lacks, to next-generation battery chemistries such as sodium-ion, solid-state, and silicon-anode, and engineered materials like advanced composites, graphene, and aerospace-grade alloys for electronics, energy, and defence. Our conviction is that a strategic chokehold becomes sovereign capability only through deep process and materials innovation, and the founders solving the refining and magnet bottlenecks are quietly building the precondition for everything else.
The IEA projects India as the single largest source of global energy-demand growth through 2035, even as the country imports nearly 87% of its crude oil, a reliance set to climb toward 92%. Purus backs early-stage deep tech founders resolving that tension at the frontier, from novel electrolyser architectures such as PEM, solid-oxide, and membrane-less designs that cut green hydrogen costs, to grid-scale and long-duration storage, carbon capture, AI-driven energy intelligence, advanced clean-mobility powertrains, and early-stage fusion. We are drawn here because India must meet unprecedented demand without importing dependency, and because the sector's real scarcity is patient capital rather than ideas, which is precisely where conviction at the earliest stage compounds into the technologies that make low-emission growth feasible at national scale.
Through the National Quantum Mission, India has committed ₹6,003.65 crore to building quantum computers of 50 to 1,000 qubits alongside communication, sensing, and materials, and indigenous full-stack machines have moved fast, from a 25-qubit superconducting system in April 2025 to a 64-qubit processor by November 2025, with a fault-tolerant roadmap beyond. Purus backs early-stage founders across the stack, from superconducting qubit hardware and indigenous cryogenic components that attack the field's hardest supply-chain bottlenecks, to quantum key distribution and post-quantum cryptography already securing defence and banking networks, to quantum sensing and AI-hybrid quantum software. What compels us is that India is placing a deliberate national bet before the field's commercial threshold settles, and the founders building integration, secure-communications, and component capability indigenously are positioned to own precisely the layers the country still imports, with fabrication the frontier that early conviction helps close. Quantum is a cross-cutting domain rather than a standalone sector, since the same capability secures defence and banking networks, accelerates drug discovery and materials design, optimises energy grids and manufacturing, and hardens the communications layer, compounding value across every core area Purus pursues.
Having deployed an indigenous 5G stack in one of the world's fastest rollouts, India now targets 10% of global 6G patents and an estimated $1.2 trillion GDP contribution by 2035 under the Bharat 6G Vision, and already ranks among the top six nations in 6G patent filings. Communications is a cross-cutting domain rather than a standalone sector, since secure high-bandwidth low-latency connectivity is the substrate beneath space and satellite systems, AI-native infrastructure, defence networks, and digital finance alike. Purus invests in deep tech ventures building the frontier of that ambition, from terahertz radios already demonstrated on indigenous testbeds and O-RAN with advanced massive MIMO and reconfigurable intelligent surfaces, to AI-native autonomous networks, non-terrestrial and satellite-terrestrial convergence, and indigenous telecom chipsets and antennas. We see the stakes plainly, because domestic capability decides whether India owns its digital infrastructure or rents it, and the founders converting the country's deployment speed and patent strength upward into the hardware and standards layer are the ones turning a technology adopter into a standards creator.
Across semiconductors, defence, space, and clean energy, the binding constraint in India is consistently the same, namely the process engineering, precision, and production competencies that design and assembly strength alone cannot supply. Advanced manufacturing is a cross-cutting domain rather than a standalone sector, because it is the production substrate that turns every other thesis from a design into a physical object at scale, which is why the same additive and robotics capability already serves aerospace, defence, automotive, and healthcare. Purus backs early-stage founders in the deep tech of making, from automated composite and metal additive manufacturing now supplying defence and aerospace, to collaborative robotics and automation, digital twins and edge-based factory intelligence, and industrial AI that moves predictive maintenance and process optimisation from dashboards into autonomous action.
