VulcanForms has built what it calls the first fully integrated digital metal manufacturing platform in the U.S., unifying metal 3-D printing, precision machining, automation, inspection, and AI-driven software into a single end-to-end workflow. By collapsing traditionally fragmented, multi-step supply chains into one domestic operation, the company reduces cost, waste, and lead time while delivering production-grade parts with consistent quality. Its facilities already support large multi-billion-dollar commercial programs across medical devices, consumer products, aerospace, defense, and other industrial sectors, signaling strong market adoption and a shift of mission-critical manufacturing back onshore. The platform’s ability to provide secure, high-performance domestic production is positioned as a key advantage amid geopolitical and supply-chain disruptions. Newly raised capital will fund capacity expansion, materials portfolio growth, and continued R&D to advance the technology roadmap. While specific revenue figures were not disclosed, VulcanForms emphasizes scaled industrial production and surging customer demand as indicators of its financial momentum.

ZeroRISC builds production-grade, OpenTitan-based silicon security designs and an Integrity Management Platform (IMP) that decouples device security from place of manufacture. Its platform is designed for integration into SoCs, chiplets, and devices across IoT to datacenter strata, enabling software-based ownership and control. The company emphasizes transparent, verifiable silicon to replace opaque hardware ‘black boxes’ and to give device owners policy control over permitted software. ZeroRISC was founded in April 2023 by Dominic Rizzo (the OpenTitan project founder) and is headquartered in Boston, MA. In February 2024 it introduced the first commercially produced OpenTitan-based chip manufactured by Nuvoton, and it is offering an early access program for the first silicon and future collaborations. ZeroRISC recently closed an oversubscribed $10 million seed round to accelerate commercial adoption and expand production and go-to-market efforts. zeroRISC offers a cloud security service for silicon built on the OpenTitan open-source silicon root of trust, delivering transparent, trustworthy device management below the operating system. The platform is presented as an all-in-one, drop-in silicon, software and services solution that enables secure ownership transfer and secure-by-default device management. The company plans open-source development of production-quality discrete and integrated roots of trust (RoTs), a proprietary integration kit for integrated RoTs, a secure embedded operating system, and proprietary cloud-based services that tie into the secure OS and silicon designs. Its first discrete open-market chip is hardened against physical attacks, supports post-quantum secure boot, and was designed to meet commercially relevant certification guidelines. The team consists of original OpenTitan project members from Google, led by founder and CEO Dominic Rizzo, and is working with commercial integration partners including Nuvoton. zeroRISC launched in April 2023 and announced its formal market debut with seed funding.

Hgen makes clean hydrogen using a higher-efficiency alkaline electrolyzer designed for industrial feedstocks like chemicals and steel production. Its electrolyzer achieves 20x higher volumetric power density versus conventional alkaline systems by using hydrogen-generating cells that are 9% more efficient and 6x thinner, resulting in a more compact and lower-cost system. The company emphasizes pre-assembled modules that include the balance of plant to avoid custom on-site construction. Hgen scaled from a benchtop prototype to an industrial-scale demonstration at its Hawthorne facility with early support from Breakthrough Energy Fellows. Founded in 2021, the company is focused on commercial deployment at customer sites and is hiring in Los Angeles. Hgen aims to address a $100B+ hydrogen market that currently produces nearly 100 million metric tons of fossil-fuel derived hydrogen per year. Hgen is building modular alkaline electrolyzers aimed at producing green hydrogen for hard-to-decarbonize industries such as steel and ammonia production. The startup emphasizes an integrated design approach to eliminate redundant parts and improve electrode design, drawing on the founders' Tesla and SpaceX experience. Initially it will focus on distributed electrolyzers sited near end-use facilities to avoid large-scale distribution and storage infrastructure. As the design is refined and production scales, Hgen envisions moving toward more centralized production in the longer term. The company is designing its systems with renewable integration in mind to allow ramping without degrading catalysts and to lower total plant costs. Hgen targets driving down the cost of green hydrogen, with an ideal long-term price goal of roughly $1 to $1.50 per kg, compared with current reported green-hydrogen costs of $3 to $8 per kg.

Swift Solar develops perovskite photovoltaic solar cells as a next-generation solar technology. The company says its advanced perovskite cells can outperform current market options. It is a spinout of MIT, Stanford University, and the National Renewable Energy Laboratory and is led by CEO Joel Jean. Swift plans to use new capital to accelerate scaling of its technology and to prepare to break ground on its first factory. The company raised $27M in a Series A to support those plans, partnering with strategic and deeptech investors. No operating metrics were disclosed in the article. Swift Solar develops solar PV products based on metal halide perovskites intended to outperform silicon and thin‑film technologies. The company says its technology could enable months‑long drone flight, EV recharging, home power, and off‑grid or disaster relief applications. Founded in 2017 and led by CEO Joel Jean, Swift Solar has focused on R&D and prototype development. The recent financing will be used to expand R&D capabilities, develop prototypes, and grow the team. Swift Solar has raised over $16M in equity financing to date and also receives non‑dilutive support from the National Science Foundation, the U.S. Department of Energy, and the Office of Naval Research. The company emphasizes performance and versatility as core product attributes.
