Satish Padmanabhan on DIMAAG’s power electronics innovations for AI data centres

In this episode, Satish Padmanabhan, co-founder and CEO of DIMAAG, unpacks his company’s innovations for the critical power infrastructure shift needed to sustain the AI revolution. Satish is a genuine serial entrepreneur, with DIMAAG being his seventh venture and also his “longest job” as he jokes. The company’s evolution goes from a smart factory quality control platform that verified 220 million disk actuators monthly to designing electric tractors to heavy-duty electrification. Satish teamed up with Tesla veteran Ian Wright to start DIMAAG and they have notched up deep intellectual property in the areas including thermal management. Today, DIMAAG is tapping its expertise to offer solutions such as ZettaWatt, an innovative 800V DC platform, that reduces disruptions as AI data centres connected to power grids become increasingly power hungry, driven by surging AI chip power density. We also dive into Satish’s views on the physical scalability limits of Large Language Models (LLMs) with current solutions, why hard, unglamorous engineering is making a massive comeback, and his insights into how global investors have begun to take notice of India’s deep tech opportunities. Chapters (02:33) The accidental transition from quality control to electric tractors (07:53) Leveraging high-voltage EV technology for the data center power bottleneck (12:56) How immersion cooling prevents battery thermal runaway in continuous operations (17:04) Why gigawatt-scale data centers are causing severe grid oscillations (22:25) Solving power oscillations on the DC side for 99.7 percent efficiency (35:12) The physical limits of scaling large language models (44:02) Building a vertical stack hardware ecosystem between Silicon Valley and India (57:34) The entrepreneurial drive to build products that stand the test of time

Pardeep Garg on heat pumps as the next big engine for India’s net zero effort

In this episode, I’m joined by Pardeep Garg, co-founder and CEO of CRID India — Centre for Research and Implementation for Decarbonization. With a background spanning IISc in Bengaluru, MIT in the US, and multiple climate-tech startups, Pardeep is uniquely positioned at the intersection of technical research and real-world execution. CRID India identifies itself as a think tank and implementation agency, focusing on “hard-to-abate” sectors in industry, and agriculture, where Pardeep points out that even though there exist well-understood technologies that are more energy efficient and therefore emission reducing, their adoption has not taken off, because of the initial costs involved, lack of awareness and so on. In this episode, he discusses examples, such as heat pumps, which he says could be India's next big success story, comparable to solar energy, and details his team's work in building the nation's first industrial heat map. More efficient motors of IE 4 or IE 5 (international energy efficiency) rating are another example, as is drip irrigation. We also discuss CRID India’s aim of becoming a “systems integrator” for energy transition in the country, where solving for climate change requires aligning policy, finance, and stakeholder interests beyond just engineering.

Mredul Sarda’s journey from student satellite to deep tech investor to cybersecurity entrepreneur

In this episode, I’m joined by Mredul Sarda, an operator-investor in early-stage deep tech and now a cybersecurity entrepreneur. Mredul’s experience-packed journey began at IIT Bombay, where he earned a BTech in electrical engineering, and an MTech in deep learning. While at the institute, he was also a member of the team that designed and launched Pratham, widely thought of as India’s first student-led satellite. After a stint in strategy consulting, his tryst with Indian startups started not with deep tech but via a vital role at the fintech company Slice, where he played an important role in scaling the venture to unicorn valuation. Mredul, who was already an angel investor, co-founded Riceberg Ventures with Ankit Anand, Lino Gandola, and Shubham Raj. The firm launched its flagship $20 million Riceberg Ventures Premier Fund I in early 2024 to back global pre-seed deep tech ventures. Even as they expand Riceberg into Silicon Valley, Mredul and Shubham have also kicked off their own entrepreneurial venture in the area of AI-led cybersecurity, with their startup Causal Security. Causal Security offers an AI-based platform building autonomous “AI hackers” to surface and defend vulnerabilities in enterprise infrastructure. Join us as to get a glimpse into Mredul’s vision for India’s sovereign technical capabilities and his own evolution from operator to investor to investor-entrepreneur. Chapters:(03:21) Early engineering roots and the IIT Bombay student satellite project (06:05) Transitioning from strategy consulting to the hyper-growth ride at Slice (09:23) The inception of Riceberg Ventures and backing "obsessed" founders (14:08) Navigating deep tech sectors from biotech to nuclear energy, (16:40) Launching Causal Security to address global AI-led cyber threats (25:27) Automating security reviews with context graphs and AI harnesses (43:44) Scaling Riceberg Ventures into the United States market (44:57) Developing sovereign technical capabilities for the India AI stack

20 million Ranchos: Prof. Ashok Jhunjhunwala’s vision for achieving tech sovereignty for India

In this episode, I’m are joined by Professor Ashok Jhunjhunwala, a doyen among India’s champions of technology-led innovation for the masses, to discuss his latest moonshot venture: the ITEL Foundation (Immersive Technology and Entrepreneurship Labs). After decades of bridging academia and industry at the IIT Madras Research Park, over the last two years, Professor Jhunjhunwala has been chairing this ambitious industry consortium-led initiative to transform India into a global “product nation.” We dive into ITEL’s unique model of forming scientific consortiums and nurturing young “Ranchos” to solve India’s most infrastructure problems – such as the need for affordable and reliable rapid mass transport, for example. Eliminating waterlogging in our cities after rains and floods, and slashing chemical fertilizer dependency in agriculture are other examples. Join us as Professor Jhunjhunwala, who turned 73 last week, explains why achieving true technological sovereignty requires 20 million entrepreneurs who view failure as a mere stepping stone to success, a critical badge of experience. Discover how ITEL is building the future of Indian innovation, one impossible challenge at a time. Chapters (01:19) The birth of ITEL and the vision for a product nation: Professor Jhunjhunwala discusses the founding of the Immersive Technology and Entrepreneurship Lab (ITEL) and its goal to transform India into a global leader in technology. (05:48) Leveraging scientific consortiums and nurturing young “Ranchos”: The strategy for ITEL involves bringing together India's top scientists from across the country and providing intense mentorship to young, talented engineers. (08:40) Solving impossible problems from urban transport to waterlogging: Professor Jhunjhunwala outlines the "impossible" challenges ITEL is tackling, including reducing long commutes to 20 minutes and freeing cities from waterlogging. (17:33) Navigating the three layers of funding for deep tech: The conversation details the specific roles of grants, government funds, and venture capital in supporting high-risk, high-impact innovations. (25:33) Why India needs 20 million entrepreneurs to achieve sovereignty: Drawing inspiration from Mahatma Gandhi, the Professor argues that true technological sovereignty requires a massive scale of grassroots entrepreneurship. (36:36) Challenging large Indian conglomerates to lead global innovation: Professor Jhunjhunwala critiques the reliance of large companies on imported technology and urges them to acquire and scale Indian deep tech startups. (38:58) Embracing failure as a critical component of learning and growth: Using the analogy of a child learning to walk, he explains why incubators must allow entrepreneurs the freedom to fail and fall in order to eventually succeed. (45:25) The roots of service: how childhood values shape leadership: The Professor reflects on how his teachers and Hindi poetry instilled the desire to serve society rather than seeking fame or money.

10 pct challenge: Vinod Shankar at Java Capital on how India can put $1 trillion in deep tech

In today’s episode of Conversations, I’m joined by Vinod Shankar, co-founder of Java Capital, a venture capital firm that has carved a unique niche by focusing on deep tech and climate technology. Vinod’s journey is as specialized as his investments, moving from writing assembly code for mobile processors to leading a fund that backs moonshots in aerospace, silicon photonics, and advanced manufacturing. Vinod recently ignited a lively debate in the startup ecosystem with his provocative essay, titled “I Want India to Win. Just Not With My Money.” He argues that India’s path to becoming a developed nation is being hindered by “sedimented” wealth. For example, consider one data point he highlights: while India’s wealthiest 1 percent control some $11.6 trillion, nearly 60 percent of those assets are frozen in real estate and gold. In other words, not funding the future, he says. He also critiques India’s largest corporations for being “structurally allergic” to R&D risk, noting that global giants such as NVIDIA outspend the entire Indian corporate sector in a single quarter. In this conversation we also talk about Java Capital’s next fund, their third, targeting Rs. 400 crore with a first close coming up, their “stacking” investment strategy, and Vinod’s urgent call for India’s ultra rich investors to allocate 10 percent of their net worth to domestic deep tech to secure the future of the nation’s technological sovereignty. Chapters (01:32) Introduction: Vinod Shankar and the “I Want India to Win” Essay (04:01) The Evolution of Java Capital: From Generalist to Deep Tech Specialist (06:56) A Unique Career Path: From Assembly Code to Venture Capital (09:34) The “Stacking” Investment Model: Connecting Portfolio Dots (13:06) Addressing the “Sediment” Wealth Problem in India (18:37) The Corporate R&D Crisis and the Need for a Virtuous Cycle (26:41) Sovereignty and the Funding Gap: Domestic vs. Foreign Capital (43:24) Java Capital’s Fund III: Moonshots and the Future of Indian Innovation
