Nyobolt closes Series C round at $1B valuation

Ultra-fast, high-power energy technology company Nyobolt announced it has raised $60 million in funding to accelerate its development pipeline and bring its power performance technologies to the autonomous machines that need them most.

The company said that this investment round was led by Symbotic, with participation from IQ Capital, Latitude (Phoenix Court), Scania Invest and CBMM.

Symbotic and Nyobolt announced a partnership in September 2025 to develop new power technology for SymBot autonomous mobile robots.

Nyobolt’s valuation reaches $1 billion

Nyobolt said that the funding follows a period of rapid commercial momentum. The investment arrives at a critical inflection point: as autonomous machines move from factory floors to warehouses, hospitals and city streets, their energy demands are outpacing conventional battery technology.

The company said that the same pressure is building inside the data center, where GPU racks running large-scale AI workloads generate intense transient power demands that legacy UPS infrastructure was never designed to handle. Nyobolt said that its ultra-fast charging technology is built for these environments, where downtime is not an option and performance cannot be compromised.

"Nyobolt is enabling the always-on, always-moving infrastructure that physical AI demands," said Sai Shivareddy, co-founder and CEO of Nyobolt. "The enterprises deploying autonomous systems at scale can't afford downtime, swap time, or power flickers. Our technology delivers a powerful trifecta: improved performance, exceptional durability, and a more sustainable operation, enabling a new generation of machines to run harder and smarter."

Powering autonomous warehouse robots

Nyobolt said that its commercial traction spans some of the most advanced autonomous robotics deployments in the world. For Symbotic's SymBot autonomous mobile robots, Nyobolt said that its performance battery delivers six times more energy capacity than the ultracapacitors previously used, is 40% lighter and achieves at least ten times the cycle life of traditional Lithium-Ion technology, enabling continuous, high-intensity 24/7 operations across Symbotic's warehouse deployments.

"We're proud to partner with Nyobolt and invest in the next phase of their growth," said Bill Boyd, chief strategy officer of Symbotic. "Nyobolt's proven technology is a key enabler of enhanced uptime and efficiency for our customers, and we're excited about the overall market potential of a new instant power infrastructure across multiple applications."

In addition, Nyobolt said that it is expanding its commercial traction beyond Symbotic to other robotics companies and applications, including with a leading humanoid developer to increase work-to-charge ratios for their humanoid robots.

Energy is a physical AI bottleneck

The company said that the rise of physical AI, robots, AMRs, industrial automation platforms and AI-enabled machinery is creating an urgent energy challenge. Unlike data center workloads, physical AI systems operate in dynamic, unpredictable environments, placing extreme and variable demands on their power sources. Traditional battery technology simply was not designed for this type of environment.

Nyobolt said that its proprietary tech stack, addresses the core limitations holding back today's autonomous systems, enabling the always-on performance that the next generation of physical AI applications requires.

Nyobolt added that it is also expanding its footprint into India, signing an MOU with the state of Rajasthan to bring more than 100MW of off-grid AI data centers and power management infrastructure to one of the world’s fastest-growing digital economies.

The company said that the Rajasthan partnership marks the first of what it expects to be a broader presence across multiple Indian states, with a particular focus on renewable energy integration and grid-independent energy storage.
