Radify develops plasma-based reactors that heat hydrogen into a plasma and blast metal oxide powders into the chamber to strip oxygen and yield pure metal, producing only water vapor as waste. The company says its design allows for smaller, more flexible reactors compared with incumbent large-scale equipment, which it believes can lower manufacturing costs and enable faster pivots between metals. Radify is focused initially on dysprosium and neodymium, key rare earths used in magnets and electronics, and is exploring additional metals including hafnium, uranium, scandium, titanium, iron, and aluminum. The five-person team is refining the technology in a lab in Campbell, California and expects to make several kilograms of pure metal per day by the end of the year. It plans to raise more capital to build a pilot reactor capable of producing up to 100 kilograms per day and to scale toward commercial competitiveness with incumbent producers. The company has raised just under $3 million to date from investors that include Overture, Founders Inc., Mana Ventures, and Acequia Capital.

Deta is a Berlin- and New York-based startup founded in 2019 that is developing Surf, an AI browser blended with a research notebook akin to Google’s NotebookLM. The beta-stage app allows users to open URLs, PDFs, and YouTube videos, then employ an integrated chatbot to summarize, extract insights, or generate code that can be saved into topic-based notebooks. Surf keeps data local so it can operate offline, and users can reference multiple open tabs as context when querying the AI. The product is currently free, and the team is experimenting with image generation while planning a future premium tier that could add cloud backup, collaboration, and multi-device sync. Deta originally aimed to build a new operating system on an infinite white canvas but sunset that effort in 2023 to focus on an AI browser opportunity. Financially, the company raised a $3.6 million seed round in 2023 and later secured an additional $500,000, bringing total funding to roughly $4.1 million. No revenue or user metrics have been disclosed.

Corintis offers advanced direct-to-chip liquid-cooling solutions that use microfluidic technology and a generative design platform to tailor cooling to individual chips. The system can act as a drop-in replacement for standard cold plates or be integrated directly inside GPUs, delivering up to three-times lower temperatures than traditional cold-plate approaches, as previously validated by Microsoft. This performance enables higher power densities, better energy efficiency, and reduced environmental impact—critical as AI workloads strain conventional data-center designs. Headquartered in Lausanne, the company is expanding its U.S. footprint with a new Washington office and scaling global manufacturing of its cooling hardware. Recently signed agreements with multiple large technology firms underscore rising commercial interest. The new capital will accelerate global expansion, mass-manufacturing, and customer rollouts. Corintis has raised $58 million to date, giving it resources to push its technology into mainstream data-center deployments.

Hyperdrives develops hollow-conductor cooling for electric motors to achieve higher current density, enabling lighter, smaller, more efficient drives with a strong performance-to-cost advantage. The company supplies turnkey drive systems with integrated SiC inverters and partners with OEMs and Tier‑1s on industrialisation and manufacturing-technology licensing. Over three product generations it has focused on delivering motors that scale using existing production processes rather than exotic materials or novel layouts. Hyperdrives targets automotive, aerospace, and marine applications and emphasizes manufacturability for industrial-scale production. The company generated over €1 million in revenue in 2024 without any external funding. Using the new financing it plans to expand the team, validate lifetime durability to automotive standards, convert its customer pipeline into commercial projects, and prepare manufacturing for industrial rollout.
