Joulent develops modular, Across-the-Meter™ baseload power solutions that integrate generation, storage, and advanced controls to serve large, compute-intensive loads. The company has an initial multi-gigawatt development portfolio and strategic partnerships with GE Vernova and Energy Forge (Chevron Power Solutions). Its first project, Kilby, will provide about 2.67 gigawatts under a 20-year power purchase agreement with Microsoft, and Joulent now holds a 50% ownership interest in that project. Joulent recently secured a $1.75 billion strategic minority investment from National Grid Ventures to accelerate growth, advance its project pipeline, and scale capabilities. The company positions its model to scale to multi-gigawatt campuses, provide exportable capacity to local power markets over time, and enable future integration of renewable energy sources such as solar. With headquarters in Houston, Joulent aims to deliver rapid, large-scale power solutions for AI infrastructure and advanced industry while expanding its team and project execution capacity.

Captura designs and manufactures a PFAS-free bipolar membrane electrodialysis platform that generates acid and base streams for applications including direct lithium extraction, industrial water treatment, long-duration energy storage, and CO2 management. The platform was originally developed to power Captura’s Direct Ocean Capture (DOC) system, which removes CO2 from seawater for permanent storage or utilization. Captura operates the only U.S.-based production plant that produces complete electrodialysis systems and plans to scale domestic manufacturing capacity following its Series B raise. The company reports that its technology offers greater performance with significantly lower energy consumption and capital costs compared with leading market alternatives. Captura recently secured multiple purchase orders for its first electrodialysis stacks addressing the lithium extraction market, with initial deliveries expected this summer. CEO Steve Oldham says the company is now manufacturing systems for customers while continuing to advance commercial deployment of DOC globally.

GridCARE develops the Energize platform, which uses physics-based AI models to evaluate grid conditions—congestion, outages, weather, and demand fluctuations—in real time to locate underutilized power capacity. The company positions this approach as a way to shorten interconnection timelines for large data centers and AI facilities from years to months by unlocking existing grid capacity. GridCARE reports active projects across more than a dozen markets representing over 2 gigawatts of prospective AI compute capacity and cites a Portland General Electric collaboration that identified a pathway to unlock more than 400 megawatts with 80 megawatts expected online in 2026. Co-founder and CTO Ram Rajagopal is a Stanford professor on leave, and the company emphasizes working collaboratively with utilities. GridCARE frames the market opportunity around a “Time-to-Energize Crisis,” arguing power availability is a growing bottleneck for AI expansion. Financially, the company recently raised a $64 million Series A in an oversubscribed round that materially increased its valuation versus a round less than a year earlier.

VulnCheck offers an exploitation-anchored threat-intelligence platform that continuously analyzes more than 500 million CVE records from over 500 sources to deliver evidence-driven insights on which vulnerabilities are being weaponized in the wild. Its data is structured for machine-to-machine consumption, allowing security products and response workflows to prioritize and act automatically rather than rely on manual analysis. During the past 12 months the company grew enterprise annual recurring revenue by 557% and government ARR by 306%, climbed to No. 22 for all-time CVE assignments with over 2,000 CVEs, and expanded its community to more than 13,000 users. VulnCheck also added nearly 900 vulnerabilities to its Known Exploited Vulnerabilities list, a 25% year-over-year increase, and found that 32% of these flaws were exploited on or before disclosure day. Recognitions such as the 2025 SINET16 Innovator award and finalist slots in multiple Black Hat Startup Spotlights underscore its market momentum. With fresh capital, the Lexington, Massachusetts company plans to further scale its growth and enhance its AI-powered threat-detection capabilities to support global enterprises, critical infrastructure operators, and sovereign governments.

Nu Quantum is pioneering distributed quantum computing by developing the Entanglement Fabric, a modular, interoperable photonic networking stack that links separate quantum processors into a single, more powerful system. Its approach targets the key industry hurdle of scaling qubit counts to reach fault-tolerant, utility-scale quantum computers. The firm has already demonstrated world-first subsystems such as a Qubit-Photon Interface slated for 2024 and a Quantum Networking Unit planned for 2025, and it is advancing research in Distributed Quantum Error Correction. Fresh capital will accelerate product development, expand its multidisciplinary team, and support international growth following the opening of a Los Angeles office and the formation of a U.S. strategic advisory board. Nu Quantum also convenes the Quantum Datacenter Alliance to foster ecosystem collaboration with quantum processing unit partners. The oversubscribed $60 million Series A— the largest pure-play quantum networking round globally and the largest quantum Series A in the UK—provides substantial runway for these ambitions.
