Tackling the Last Metre: Ultrafast Charging and Physical AI Infrastructure with Sai Shivareddy
In this episode of DeepTech Unleashed, host Christian Noske sits down with Sai Shivareddy, the CEO and co-founder of Nyobolt. Born out of a decade of cutting-edge research at the University of Cambridge, Nyobolt is a battery scale-up tackling the all-important last metre of energy storage. Their revolutionary technology enables ultrafast charging, reaching an 80% charge in under five minutes, without the typical degradation associated with conventional lithium-ion batteries. Sai shares his 15-year journey across the battery value chain, reflecting on how early research funded by Dyson sparked his entrepreneurial drive. The conversation dives deep into the strategic choices that have driven Nyobolt's success, including a deliberate choice to focus on application-layer solutions and power density to uniquely solve industrial pain points. Sai also details the reality of navigating multiple hype cycles, building commercial credibility, and the milestone achievements that have validated their hardware stack—from a groundbreaking sports car demonstration to capturing massive automation contracts with reference customers like Symbotic.
