A Cambridge-based battery startup has crossed the billion-dollar valuation mark.
Nyobolt, which makes ultrafast-charging batteries for warehouse robots and AI infrastructure, has raised $60m in a Series C, bringing its total funding to around $160m.
The round was led by Symbotic, a Nasdaq-listed AI robotics company whose warehouse robots already run on Nyobolt's batteries. IQ Capital, Latitude, Scania Invest, and CBMM also participated.
The raise follows a significant pivot at the battery startup.
Nyobolt originally made its name with an electric sports car prototype capable of charging from 10% to 80% in under five minutes – and was in talks with eight vehicle manufacturers about licensing its technology. It has since pivoted toward robotics.
"Choosing not to be defined by our EV story opened pathways into industries where the stakes are higher and the impact is broader," co-founder and chief executive Sai Shivareddy told the publication Pulse 2.0 in September 2025.
Nyobolt's batteries purportedly give Symbotic's autonomous warehouse robots six times more energy capacity than the ultracapacitors they previously used, at 40% lighter weight.
Nyobolt is also working with an unnamed humanoid robotics developer to extend operational runtime between charges, and signed a memorandum of understanding with the Indian state of Rajasthan to support more than 100 megawatts of off-grid AI data centre infrastructure.
Nyobolt was co-founded by Shivareddy and Professor Clare Grey, a Royal Society fellow and battery materials scientist at the University of Cambridge.
The company employs around 115 people.
