Claros announced it has raised an oversubscribed $30 million seed round co-led by General Catalyst and Red Cell Partners, with participation from Systemiq Capital, Aero X Ventures, Trenches Capital, and other investors. The company is focused on improving how power is delivered and managed across data centers, particularly as AI workloads drive significant increases in energy demand.
The company is building what it describes as a “chip-to-grid” platform designed to address inefficiencies in both power delivery to computing hardware and energy management at the facility level. Its approach combines an integrated voltage regulator, which delivers power directly to processing units, with a DC-native Power Gateway that reduces losses from AC to DC conversion and integrates with multiple power sources.
Claros aims to tackle what it sees as a growing challenge, the unsustainable strain that data centers place on electrical grids, alongside the inefficiencies operators face when relying on fragmented power solutions for new builds. By rethinking the entire power stack, the company is working to enable faster deployment, improved efficiency, and lower energy waste across AI infrastructure.
Since emerging from stealth in early 2025 with $9.75 million in initial funding, Claros has made progress on both hardware and team expansion. The company has developed multiple integrated voltage regulator designs, including a first version that validated its architecture and a more advanced version currently undergoing testing. It is also preparing a new design based on customer requirements for fabrication.
Claros has completed initial hardware and software designs for its Power Gateway and assembled a demonstration unit for lab testing. The company has grown its team to 26 employees across its Los Angeles lab and Northern Virginia office.
One of the company’s key innovations is a scalable mesh network architecture that enables power delivery to scale from a single 40-amp module to clusters capable of delivering more than 40,000 amps, addressing the increasing demands of high-performance AI systems.
With the new funding, Claros plans to expand its lab capabilities, grow its team, continue prototyping its core technologies, and begin initial manufacturing runs. The company’s broader goal is to reduce energy consumption, improve compute performance, and make AI infrastructure more efficient and resilient.
KEY QUOTES:
“We can’t ignore the immense energy demands that come with AI workloads and the strain they place on electrical grids throughout the United States and around the world. To address these concerns, we must reinvent the entire power system with meaningful solutions that minimize energy waste so data centers can unlock greater efficiency and productivity. At Claros, we are committed to responsible power delivery—from the chip all the way to the meter. In the 13 months since our launch out of stealth, we’ve worked tirelessly to resolve this issue, demonstrating significant progress toward efficiency gains that point to a larger opportunity across the entire power stack. Our IVR is only the starting point in our quest to help data centers more efficiently source, store, and use power end-to-end.”
Daniel Kultran, Co-Founder And CEO Of Claros
“The power infrastructure supporting AI is one of the most significant investment opportunities of our time. Solving it requires rethinking the entire energy stack and a team with unique experience and technical depth to transform power management. In just 13 months, Daniel Kultran and the Claros team have made tremendous progress in modernizing power delivery from the chip to the grid.”
Paul Kwan, Managing Director At General Catalyst
“Better power delivery at the chip level is essential to unlocking the next generation of data center performance. What stood out to us was Dan and the team’s track record in power electronics and their vision for the full power architecture, from chip to grid, making Claros exactly the kind of frontier company we are proud to back.”
