Marvel Fusion develops laser-based nuclear fusion using inertial confinement, where ultra-short pulse lasers target nano-structured fuel capsules to initiate fusion reactions. The company positions its technology to provide clean, safe and reliable energy at commercial scale. In April 2025 Marvel Fusion extended its Series B by €50M, bringing the total raised in the round to $113M. The firm intends to use the funds to build a prototype facility by 2032 and aims to have a commercial fusion power plant operational by 2036. Founded in 2019 and led by CEO Moritz von der Linden, Marvel Fusion is based in Munich, Germany. Investors in the extension include EQT Ventures, Siemens Energy Ventures and the European Innovation Council Fund, with existing backers Tengelmann Ventures and Bayern Kapital participating. Marvel Fusion is developing an inertial confinement fusion approach that uses cutting-edge femtosecond lasers to ignite fusion in nanostructured targets. The company designs silicon-based targets manufacturable with standard semiconductor lithography at ~50–80 nm feature sizes, enabling production of roughly 5,000 targets per 300 mm wafer. Its fuel strategy is a mixed-fuel approach (mainly hydrogen and boron) and solid-room-temperature fuel to simplify handling versus cryogenic pellets. Marvel plans a demonstration facility in collaboration with Colorado State University to operate two 100-joule lasers by early 2027, with energy upgrades planned in 2028–2029. A commercial-scale prototype containing 10–20 two-kilojoule lasers firing ~10 times per second is targeted for around 2032–2033. The company emphasizes mass manufacturing and faster firing rates as core differentiators from legacy laser fusion systems. Marvel Fusion is developing fusion energy technologies that use short-pulse lasers and nanostructured targets to trigger non-thermal nuclear fusion reactions. The approach is based on 2018 Nobel Prize-winning work by Donna Strickland and Gérard Mourou and accelerates fuel particles through engineered nanostructures. The company aims for the development and commercial realisation of fusion energy using this laser-driven, non-thermal pathway. Marvel Fusion was founded in 2019 and its team includes experts in nanotechnology, plasma physics, computational science, optics, and short-pulse laser physics. It counts Siemens Energy, TRUMPF, and Thales as technology partners. Financially, the company has recently completed a €35 million Series A and has raised €60 million in total to date.

Seurat Technologies provides a 3D metal printing system designed for high-volume, decarbonized industrial production. The company intends to use new funding to accelerate its 3D metal printing technology and move from prototype to production. Seurat plans to deploy printing factories at or near customer sites worldwide to produce parts closer to demand, reshore supply chains, and reduce emissions from transportation and global logistics. Its pilot factory in the Greater Boston area will have capacity to produce more than 25 tons of metal parts annually and is already oversubscribed. Seurat has commitments to develop 59 tons of additively manufactured metal components for Siemens Energy over six years, LOIs from six customers totaling 4,000 tons of material, and over $750 million in projected revenue over the next several years. The company anticipates its technology could directly mitigate as much as 100 million tons of CO2 by 2030 and holds over 275 patents and trademarks, granted and pending. The company is led by CEO James DeMuth and is based in Wilmington, MA. Seurat Technologies provides scalable metal additive manufacturing technology and components manufacturing via its patented Area Printing platform. The Area Printing process decouples resolution and speed, enabling gains in lead time, cost, and quality. The technology originated at Lawrence Livermore National Laboratory; CEO and co-founder James DeMuth was a co-inventor and key developer. Seurat holds over 130 patents granted and pending. The process can be powered by 100% renewable energy and allows greater materials recycling, positioning the company to significantly reduce carbon emissions—0.15 GT of annual emissions displacement is expected by 2025. Seurat's commercialization program is slated to launch this year, and the company has received LOIs from leaders in automotive, aerospace, energy, and industrial manufacturing. Funding will support the initial commercial rollout, hiring, and development of a production-grade system. Seurat Technologies commercializes Area Printing, a metal additive manufacturing process that focuses over two million controllable laser points on a bed of metal powder to produce production-grade components. The process emphasizes per-point control of laser power and duration to deliver resolution, part integrity, and reliability at scale. Seurat says its first system generation will cut cost per part by about 50% versus today’s additive manufacturing technologies and that future printers could reach manufacturing costs below conventional die casting by 2030. The technology originated at Lawrence Livermore National Laboratory and was developed by a team that included Seurat’s CEO and co-founder James DeMuth. Seurat plans to use new funding to accelerate development and commercialization of Area Printing. The company is based in Wilmington, Mass., and previously raised $13.5 million in a Series A led by True Ventures in January 2018. Seurat Technologies builds industrial-scale metal printers aimed at cost-effective, high-throughput metal additive manufacturing. Its approach leverages technology originally developed at Lawrence Livermore National Laboratory and the company has applied for more than 20 patents. Seurat’s printers are designed for industrial scalability, likened to large-format laser engraving machines for manufacturing. The company intends to use new funds to accelerate commercialization of its metal additive manufacturing technology. Seurat was founded in July 2015 and is based in Boston, MA. Prior to this round it raised a $3.41M seed financing in June 2016 led by True Ventures.
