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.
