Ventory builds inventory software that integrates natively with enterprise systems including SAP, Oracle, Microsoft Dynamics 365 Business Central and Sage to track stock across service vans, depots, consignment inventory and customer sites. The platform replaces manual, spreadsheet- and paper-based workflows to give companies real-time visibility once inventory leaves the warehouse. Ventory is ISO/IEC 27001 certified and is used by organisations across seven countries, including healthcare providers, medical distributors, energy producers, asset managers, a national railway operator and a medical robotics manufacturer. The company was founded by Vishal Punamiya. Its near-term plans include expanding ERP integrations, advancing its AI product roadmap and growing its enterprise go-to-market presence in Western Europe.

Immaterial is a Cambridge-based advanced materials and engineering company focused on delivering scalable decarbonization technology for hard-to-abate sectors. Leveraging Nobel Prize–winning chemistry, the firm has created proprietary monolithic metal-organic frameworks (m-MOFs) that pair ultra-dense, macroscopic crystals with high gas-storage performance and strong thermal and chemical stability. Its "Wet-AI" platform fuses digital material discovery, green chemistry synthesis, and machine-learning optimization to design MOFs for carbon capture, hydrogen storage, water harvesting, and energy-efficient HVAC applications. Immaterial claims to be the only company able to produce MOFs in monolithic form, yielding significant footprint and cost reductions for industrial systems. The company is commissioning a multi-tonne manufacturing facility in Cambridge and intends to roll out Generation 2 pilot projects with partners across Europe and the United States. Strategic investor Finindus brings steel-sector expertise to help target that industry, while existing backers continue to support scaling efforts. The recently secured £13.5 million Series A2 round strengthens the firm’s financial position, although revenue and user figures have not been disclosed.

MagREEsource develops technology to manufacture permanent magnets from recycled rare-earth materials, offering magnets with a 91% lower carbon footprint compared with magnets from Chinese mining. The company operates a pilot plant in Noyarey that became operational in December 2024 and has a current capacity of 80 tonnes per year. It employs 50 people and uses two core processes that will form the basis of its future large-scale factory. MagREEsource plans a MagFactory targeted to reach 1,000 tonnes per year by 2028 and has been labeled a "Projet Stratégique Européen" under the EU Critical Raw Material Act. The startup aims to build a sovereign, low-carbon supply chain for magnets and to reduce dependence on the Chinese market. Target markets include wind power, aerospace, robotics and defense.

Hyperheat is an Offenburg, Germany–based startup that develops electric heaters for steel, cement, and chemicals industries. It is building an all-electric heating solution designed to reach temperatures of up to 2,000°C using renewable electricity as an alternative to fossil-fuel combustion. The technology is intended for retrofitting industrial processes and aims to enable significant CO2 reductions across heavy industries. Hyperheat describes its approach as scalable and cost-efficient for decarbonizing thermal processes. The company projects a potential to reduce global CO2 emissions by over 4.5 gigatons annually. Founded in 2023 by Dr. Lars Amsbeck and Frederick Lessmann, it plans to use recent funding to expand operations and development efforts.

Fortius Metals develops patented wire-based additive manufacturing alloys and robotic welding processes for large-format 3D printing, with in-house wire manufacturing and wire-arc and wire-laser (wire DED) printing cells. Its proprietary alloys (e.g., 6061-RAM2 and 7075-RAM2) claim up to twice the strength of current commercial welding/printing solutions and improved corrosion resistance and thermal conductivity. Customers and partners include the Army, Navy, Air Force, NASA, several defense primes, and commercial space companies. The company says its predictive toolpaths and process expertise deliver dimensional accuracy for complex, high-performance parts. Fortius plans to launch additional wire alloys in 2025, including IN625-RAM, 316L-RAM, and 5183-RAM, and aims to reshore metal manufacturing supply chains and create skilled U.S. manufacturing jobs. The company was formed in 2021 and is headquartered near Boulder, Colorado. Fortius Metals develops large-format additive manufacturing systems and patented nanostructured metal alloy wires that enable welding and 3D wire fabrication using high-performance alloys. Its proprietary 6061 aluminum welding wire is designed to solve traditional 'hot cracking' problems, and Fortius says its welds are often twice the strength of incumbent commercial options. The company was formed as a spinout from Elementum 3D; Elementum is headquartered in Erie, CO, and Fortius identifies as a Colorado company. Fortius aims to reshore the metal manufacturing supply chain and support highly skilled jobs in American factories while serving aerospace, automotive, and defense customers. The company intends to use new funding to scale manufacturing capacity, grow the business, and accelerate its go-to-market strategy. AM Ventures is positioned as a strategic partner given its focus on industrial additive manufacturing. Fortius Metals develops reactive additive manufacturing for metal 3D printing, aiming to produce parts for aerospace, automotive and defense markets. Its process introduces new components into metallurgy to improve grain structure and yield stronger, lighter parts. The company is focusing initial work on aluminum, a lightweight metal growing in manufacturing use. Fortius is a spinout of Erie 3D printing company Elementum 3D and was incorporated June 21. The company has two employees and is hiring engineers while seeking commercial facilities to lease. About half of the newly raised capital will be used to purchase capital equipment, and the company plans to move immediately into a seed round.
