The Battery Everyone Uses Is The One They'd Never Build | EnerVenue x HiNa | WTF are Batteries?
10/08/2026 | 1h 10 mins.I went to Dalian with a selfish question. I run a fund that invests in energy transition, and I've come to think energy isn't the problem moving it and storing it is. So I sat down with Henning Rath, who runs EnerVenue out of Silicon Valley and is building his first gigafactory in Changzhou, and Tang Kun, who runs HiNa Battery, a sodium-ion company spun out of the Chinese Academy of Sciences that's now ten years old with 600 people and a gigawatt line. I told them I don't know anything about batteries and asked them to teach me. We started at what a cell even is, went through why the entire industry standardised on LFP and what a thermal runaway actually does, and then Henning told me something I hadn't heard: the world had over 14,000 LFP fires last year alone. I asked whether I should start an electric car company or a battery company when I get home. Both said battery and Henning was blunt about it: don't build anything that needs rare earth. Fifty million dollars to start. We got into nickel-hydrogen at 30,000 cycles, sodium carbonate at a tenth of what lithium carbonate costs, why solid state is still at level four out of nine, and the idea I keep coming back to that your car sits idle 98% of the time with a battery and a stack of chips doing nothing, and there's a version of this where every parked car is a micro data center.

#WTFareBatteries #EnerVenue #HiNaBattery #SummerDavosWhy The Next Battery Won't Need Lithium Or Rare Earth | Nikhil Kamath | WTF Is A Battery
09/08/2026 | 0 mins.I went into this wanting one answer, if I were starting something today, should it be an electric car company or a battery company and what I got back was narrower and more useful than I expected: don't build the thing that needs rare earth. We got into why sodium carbonate sits at roughly a tenth of what the equivalent lithium inputs cost, what $50 million actually buys you if you're starting this from scratch, why the world saw over 14,000 LFP fires last year alone and what that says about the chemistry everyone standardised on, and the part I keep coming back to that your car is parked 98% of the time in front of your house, and there's a version of this where that's not a dead asset but a micro data center. Every car a token factory. I didn't see that coming.

#WTFareBatteries #EnerVenue #HiNaBattery #SummerDavosAbundance vs Scarcity: We Built 20 Brands With 30 Strangers In 90 Days | The Foundery
26/06/2026 | 1h 35 mins.The street believes struggle makes the founder, so we removed the struggle — twenty-five strangers, a brand and four crores each, ninety days in one house in Alibaug and then sat down to ask the only question that scared us: does a head start make a founder, or unmake one? Nikhil Kamath, Kishore Biyani and Ronnie Screwvala audit the model, the equity split everyone questions, the two philosophies built into this house, and what the three of us will do if twenty brands don't sell.

#WTFiswithnikhilkamath #PeopleByWTF #WTFOnline- So we ran an experiment. We call it The Foundery. Sixty days ago, twenty-five people we'd never met moved into a house in Alibaug — each one handed a new-age consumer brand, four crores, and ninety days to build a real business with us. Not a college, not an accelerator: a place where we become your co-founders and build the company alongside you. In this first conversation, Nikhil Kamath, Kishore Biyani and Ronnie Screwvala get into why we built it, what we're risking, and what happens if none of it works.

#WTFiswithnikhilkamath #PeopleByWTF #WTFOnline Why One New Drug Takes Ten Years To Make | Mankind x Dr. Reddy's | WTF is Pharma?
17/06/2026 | 2h 51 mins.I got two of the biggest names in Indian pharma into one room, Rajeev Juneja of Mankind and GV Prasad of Dr. Reddy's, who'd somehow never actually met before this, and what came out was part masterclass and part origin story, from why being relentlessly contrarian beat following the herd, to how a college dropout from Meerut turned everything he hated about a medical store into a pharma giant, to why a chemical engineer who says he owes his career to his marriage spent decades chasing one original molecule, and somewhere in between we got into why India makes the world's generics instead of discovering its own drugs, what it really takes in time and money to bring a single drug to market, why GV thinks the AI-will-cure-everything story is overstated, where GLP-1s go next, and the one thing they'd tell a 25-year-old trying to build in pharma.
