- Aston Power
Led · Equity · Jun 2026
Aston Power builds a coordinated power delivery platform that works across generation, transmission, firming, and delivery infrastructure to help customers secure reliable large-scale power with greater speed and predictability. The company targets data centers and other energy-intensive industrial projects facing constrained utility capacity and compressed timelines. Aston reports a service pipeline of about 2 gigawatts and has ongoing data center projects in Arizona, New Mexico, and Texas. Founded in 2022 and headquartered in Raleigh, N.C., the company raised $20 million in strategic equity from investors including TDK Ventures, Building Ventures, and JLL Spark Global Ventures. Aston intends to use the proceeds to scale operations and expand its geographic footprint to serve growing AI and industrial power demand. The company positions its offering as a full-stack, coordinated alternative to fragmented approaches that force customers to manage multiple power elements themselves.
- Exponent Energy
Led · Series B · Jun 2026
Exponent Energy develops a proprietary full-stack energy solution that enables 15-minute rapid charging for commercial EVs and offers a 3,000-cycle life warranty using regular lithium-ion cells. The company combines its battery and charger technology with the Exponent OTO mobility platform and Exponent ONE financing and asset-management arm to address energy, vehicles and access to capital. Exponent highlights interoperability across its charging stations, millions of charging sessions and more than three years of field performance as evidence of commercial readiness. It aims to become the preferred energy partner for OEMs and to power millions of commercial vehicles across India. The company plans to use new capital to expand into additional cities and vehicle categories and to strengthen R&D as it scales its energy and asset-management offerings.
- C2i Semiconductors
Led · Series A · May 2026
Founded in 2024 by former Texas Instruments engineers and technologists, C2i Semiconductors is developing a redesigned "grid-to-core" power-delivery architecture intended to address last-inch power and thermal constraints in AI infrastructure. Its platform includes the Manas Controller, a software-defined controller that adapts to changing processor and power-delivery requirements, and the Sarayu Power Stage designed to improve conversion efficiency and reliability. The company projects its platform can deliver more than 96% power conversion efficiency versus roughly 94% for existing solutions, and estimates a 100MW AI data center could realize about $12 million in annual energy savings. C2i also claims its technology could allow processors to run up to 4°C cooler and supports modular scalability for high-current applications, anticipating future processors that may require much higher peak currents. The company is using Series A proceeds to accelerate development of its platform and to move toward mass production with support from strategic investors such as TDK Ventures.
- Eridu
Participated · Series A · Mar 2026
Founded in 2024 by serial networking entrepreneur Drew Perkins and chip designer Omar Hassen, Eridu is redesigning data-center networking from the silicon up to meet the bandwidth demands of modern AI workloads. The company is building a switch that integrates far more networking functionality directly onto the chip, reducing optical links, lowering latency, and cutting power and cost compared with traditional multi-tiered architectures. Its eventual product line will replace conventional gear from vendors like Arista Networks in AI data centers, positioning Eridu at the heart of the ongoing build-out of GPU clusters that now span millions of processors. Perkins argues that while GPU compute and memory bandwidth are improving roughly 10× per year, incumbent switch technology advances only 2–3× every few years, creating a performance gap Eridu aims to close. The startup has assembled roughly 100 employees and leverages the founders’ deep experience, including Perkins’ past exits such as Lightera, Infinera, and Gainspeed. Although the company has not disclosed revenue metrics or valuation, it has raised substantial capital to fund product development and scale.
- The Guild
Led · Series A · Jan 2026
Founded in 2022 as Ethereal Exploration Guild (formerly EtherealX), The Guild is developing Razor Crest Mk-1, a medium-lift, fully reusable rocket capable of delivering up to 24.8 tonnes to Low Earth Orbit and 10.8 tonnes to Geosynchronous Transfer Orbit. Both the booster and upper stages are engineered for recovery and re-flight, targeting launch costs of about USD 500 per kilogram. The vehicle is powered by two in-house engines: the 1.2 MN semi-cryogenic Stallion for the first stage and the 80 kN Pegasus for the upper stage, which employs a Full-flow Segregated Cooling Cycle to enable upper-stage reusability. The company is expanding its infrastructure with a new BASE-002 facility in Andhra Pradesh to support integrated engine and stage testing, supplementing its existing BASE-001 site in Tamil Nadu. Upcoming milestones include engine-level and stage-level testing of its technology demonstrator. Following its Series A round, The Guild’s valuation has risen 5.5× to USD 80.5 million, and its total funding stands at USD 25.5 million. The fresh capital will finance further development and flight qualification of Razor Crest Mk-1.
