The Lithium Mine in Your Drawer: How a Delhi Startup Is Extracting 98% Pure Lithium from Dead Batteries—And Building the Circular Economy of the EV Age

In a facility that smells faintly of metal and electrolytic fluid, on the industrial outskirts of Ghaziabad, a machine the size of a shipping container is quietly solving two of the most urgent problems of the electric‑vehicle revolution simultaneously. The machine is a hydrometallurgical extraction plant, and it is fed by a conveyor belt that carries a steady stream of dead lithium‑ion batteries—the discarded cells from electric two‑wheelers, three‑wheelers, and consumer electronics that would otherwise be destined for a landfill. The plant dissolves the batteries in a carefully controlled chemical bath, separates the materials, and extracts the lithium, cobalt, nickel, and manganese that the batteries contain—with a purity that, for lithium, exceeds 98 percent. The lithium that emerges from the Ghaziabad plant, in the form of a fine, white powder, is chemically identical to the lithium that was mined from a salt flat in Chile or a spodumene deposit in Australia. It can be sold directly to a battery manufacturer and used to build a new cell. The battery that died in a Delhi scooter last year will, within months, be powering a new scooter on the same streets.

The Radiologist in Your Pocket: How a Bengaluru AI Startup Got FDA Clearance to Read X‑Rays in 3 Seconds—And Is Taking on the Global Radiology Crisis

In a modest office in Bengaluru's Koramangala district, a young radiologist sits at a workstation that would be unremarkable in any hospital in the world—a high‑resolution monitor, a keyboard, a mouse. What is remarkable is what is happening on the screen. The monitor is displaying a chest X‑ray, and the image is being analysed in real time by an artificial‑intelligence model that can detect 14 different pathologies—pneumonia, tuberculosis, lung cancer, rib fractures, pleural effusion, and nine others—with an accuracy that, in clinical trials, exceeded the performance of a panel of board‑certified radiologists. The AI takes approximately 3 seconds to read the image. It highlights the areas of concern, generates a draft report, and assigns a confidence score to each of its findings. The radiologist reviews the report, makes any necessary corrections, and signs off. The entire process, from the moment the X‑ray is captured to the moment the final report is delivered to the referring physician, takes less than 5 minutes. In a conventional hospital, the same process would take between 4 and 24 hours, depending on the workload of the radiology department.

The Submarine That Thinks for Itself: How a Chennai Startup Is Building Autonomous Underwater Drones for the Indian Navy—And the Global Market Is Watching

Sometime in the spring of 2023, a small, unmanned underwater vehicle slipped beneath the surface of the Bay of Bengal, approximately 12 nautical miles off the coast of Chennai. It was a test, and the observers—a handful of engineers from a Chennai‑based startup called Sequent Robotics, a few officers from the Indian Navy’s Directorate of Indigenisation, and a representative from the Defence Research and Development Organisation—watched the telemetry on a ruggedised tablet as the vehicle descended to a depth of 300 metres, navigated a pre‑programmed course, identified a simulated mine using its onboard sonar, and returned to the surface. The test lasted approximately four hours. The vehicle performed flawlessly. The Navy officers, who had been sceptical of the startup’s claims, were impressed. The test was a proof of concept—a demonstration that an Indian startup, operating on a budget that was a rounding error by the standards of the global defence industry, could build an autonomous underwater vehicle that was capable of performing missions that the Navy had historically reserved for its most advanced manned submarines

The Invisible Bank: How a Mumbai API Startup Built a $50 Million ARR Business by Powering the Financial Products of Every App You Use—Without Ever Touching a Customer

The Invisible Bank: How a Mumbai API Startup Built a $50 Million ARR Business by Powering the Financial Products of Every App You Use—Without Ever Touching a Customer

When a customer on a popular food‑delivery app pays for their meal in three interest‑free instalments, they are not interacting with a bank. When a freelancer on a gig‑economy platform receives an advance against their next week’s earnings, they are not borrowing from an NBFC. When a small business on an e‑commerce marketplace gets a working‑capital loan within 15 minutes of applying, they are not filling out a bank’s paperwork. In each of these transactions—and in millions of others that occur every day across India’s consumer‑internet economy—the financial product is being delivered by a Mumbai‑based startup called FinCore Infrastructure, which has built a set of APIs that allow any app, any platform, or any marketplace to embed lending, insurance, and wealth‑management products directly into its own user experience, without ever needing to acquire a banking licence, build a risk‑engine, or hire a compliance team.

The Gene Scissors: How a Coimbatore Biotech Startup Is Rewriting the DNA of India's Crops—And the Farmers Who Are Betting Their Harvest on It

In a modest greenhouse on the outskirts of Coimbatore, beneath rows of LED lights that mimic the spectrum of the Tamil Nadu sun, a crop of rice is growing that is unlike any rice that has ever been grown on the subcontinent. Its leaves are a deeper green, its stalks are thicker, and its roots—visible through a transparent panel in the soil bed—are longer and denser than those of the conventional variety that farmers in the Cauvery delta have been planting for generations. The difference is not the result of traditional cross‑breeding, which takes a decade or more to produce a new variety, nor of transgenic modification, which involves inserting foreign genes into the plant's genome and which has been effectively banned in India for food crops for over a decade. The difference is the result of CRISPR, the gene‑editing technology that allows scientists to make precise, targeted changes to a plant's own DNA—switching off the genes that make it vulnerable to drought, for instance, or enhancing the ones that allow it to absorb nutrients more efficiently—without introducing any foreign genetic material. The rice growing in the Coimbatore greenhouse has been edited, not modified, and the distinction is the foundation of a regulatory revolution that is transforming Indian agriculture.

The Toothpaste Rebel: How a 22-Year-Old Is Building a ₹500 Crore D2C Oral‑Care Empire—and Taking On Colgate, Pepsodent, and a Century of Inertia

The Toothpaste Rebel: How a 22-Year-Old Is Building a ₹500 Crore D2C Oral‑Care Empire—and Taking On Colgate, Pepsodent, and a Century of Inertia

In the summer of 2023, a 19‑year‑old college dropout stood in a small, rented laboratory in Mumbai's SEEPZ industrial zone, holding a beaker of a murky, charcoal‑black liquid that he believed would change the way India brushed its teeth. His friends thought he was insane. His family—a middle‑class Marwari household that had indulged his entrepreneurial experiments since he had started a dropshipping business at 15—was supportive but anxious. His potential investors, the handful of angel networks he had approached, were polite but dismissive. The oral‑care market was a fortress, they told him. It was dominated by Colgate and Pepsodent, which together controlled over 60 percent of the Indian toothpaste market, and by Hindustan Unilever, which controlled much of the rest. The barriers to entry—the manufacturing scale, the distribution networks, the advertising budgets—were insurmountable for a startup. The idea that a teenager with a beaker of charcoal toothpaste could compete with the giants was, depending on whom you asked, either naïve or delusional.
