KEY TAKEAWAYS
- Nyobolt closed a $60 million Series C round led by Symbotic, with participation from IQ Capital, Latitude (Phoenix Court), Scania Invest, and CBMM.
- The raise values the Cambridge company at $1 billion, making it the UK’s latest deep tech unicorn.
- Nyobolt revenues grew five times year-on-year ahead of the round, driven by demand from autonomous warehouse robots and AI data centre operators.
- The company is simultaneously expanding into Asia, signing an MOU to deploy more than 100 megawatts of off-grid AI data centre and power management infrastructure.
Nyobolt, the Cambridge-based energy tech firm, has reached a $1 billion valuation following the close of a $60 million Series C funding round led by Symbotic, the Nasdaq-listed AI-enabled robotics company operating across the US.
The round also drew participation from IQ Capital, Latitude operating under its Phoenix Court brand, Swedish truck manufacturer Scania Invest, and CBMM, the Brazilian niobium mining group that supplies a key material for Nyobolt’s battery technology.
The milestone aligns Nyobolt with a growing cohort of 2026 UK deep tech unicorns, a trend accelerated by the UK government’s £500 million commitment to backing domestic frontier technology ventures.
What Nyobolt’s Technology Does and Why Symbotic Needed It
Nyobolt builds ultra-fast, high-power batteries for environments where conventional lithium-ion fails: autonomous robots requiring zero downtime, GPU racks for continuous AI inference, and uninterrupted industrial systems.
Their proprietary niobium-based anode enables significantly faster charging and far more charge cycles before degradation.
For Symbotic’s SymBot autonomous mobile robots, operating at continuous intensity, these batteries deliver six times more energy than previous ultracapacitors, are 40 per cent lighter, and offer ten times the cycle life of traditional cells.
Symbotic confirmed Nyobolt’s revenues grew fivefold year-on-year ahead of the round, reflecting commercial deployment acceleration that compelled investors to lead the Series C.
This growth story, mirroring capital flows into London’s construction robotics and physical AI sectors, has now reached the energy layer, making such machines viable at scale.
The AI Data Centre Demand Driving Nyobolt’s Second Growth Engine
Alongside its robotics commercial base, Nyobolt has identified AI data centres as a structurally urgent second market.
GPU racks running large-scale AI inference workloads create intense, high-power draws that older uninterruptible power supply systems were not designed to handle cleanly.
A millisecond power flicker can corrupt active AI inference jobs across an entire rack. Nyobolt’s ultra-fast discharge capability addresses this failure mode, making its technology critical infrastructure for any data centre operator running AI at production scale.
The same capital pressure driving UK and European startups toward larger funding pools is also forcing data centre operators to urgently resolve power quality issues, with Nyobolt sitting at the intersection of both.
Asian Expansion and What Comes Next
The Series C capital will fund both Nyobolt’s commercial acceleration and a significant geographic expansion.
The company has signed a Memorandum of Understanding with India to deploy more than 100 megawatts of off-grid AI data centre and power management infrastructure across one of the country’s fastest-growing digital markets.
Nyobolt expects this partnership to be the first of several state agreements, with a focus on renewable energy integration and grid-independent storage that reduces dependence on intermittent national grid supply.
The international push arrives as UK deep tech firms face pressure to scale quickly to maintain their competitive edge. This dynamic is further intensified by US tariff threats on British tech exports, forcing firms to diversify revenue across multiple geographies simultaneously.
