GravitHy is a Marseille-based company founded in 2022 that develops low-carbon Direct Reduced Iron (DRI) and Hot Briquetted Iron (HBI) for the decarbonised steel industry. Its core product is DRI/HBI produced using green and low-carbon hydrogen, positioned as a fast solution for steelmakers that want green steel without investing in the full H2-DRI value chain. The company plans a flagship plant in Fos-sur-Mer scheduled for commissioning at the end of 2028 on a 75-hectare site, producing 2 million tonnes of DRI/HBI per year. That plant will use on-site green hydrogen with an electrolyser capacity of approximately 750 MW and represents an overall project investment of €2.2 billion. GravitHy says the project will create up to 500 direct jobs and aims to secure key contracts, complete engineering, obtain permits, and attract talent ahead of a final investment decision targeted for 2026. The company closed a €60 million funding round to finance this action plan and accelerate growth amid strong European policy support for industrial decarbonisation.

HT Materials Science develops MAXWELL, a water- and glycol-based heat transfer fluid additive. MAXWELL is an engineered suspension of aluminum oxide nanoparticles that increases heat transfer efficiency of commercial and industrial HVAC systems by circa 15%. The company was formed after CEO Thomas Grizzetti and partners connected with a European engineering team commercializing nanomaterials. HTMS has surpassed $2 million in total revenues with over 20 active client sites and completed pilots with Aramco, Tabreed (Engie) and Amazon, including installations at three Amazon UK fulfillment centers. The company is testing new raw material inputs including graphene to provide a more effective and less expensive product. HTMS has raised over $30 million in funding from investors including Aramco Ventures, EcoLab, Barclay Sustainable Impact Capital and CDP Ventures and targets a TAM of $100+ billion with a goal of capturing roughly 1%.

Guidewheel provides a FactoryOps platform that connects to any machine via non-invasive sensors that clip onto a machine’s power draw to deliver a real-time "heartbeat" into an AI system. The platform aims to bring cloud and AI capabilities to every machine on the factory floor, enabling teams to reduce lost production time, increase efficiency, and track energy and carbon for sustainability goals. Customers report an average of 41% more production from existing assets, and the company says it works with hundreds of manufacturers globally, including names like General Motors, Kimberly Clark, Johnson & Johnson, and U.S. Steel. Guidewheel has recently released Scout, an AI-powered predictive maintenance feature that detects early warning signs to prevent downtime and quality defects. The company plans to accelerate product development, scale its AI team, and invest in Customer Success to support a rapidly growing customer base. Guidewheel was founded out of Stanford and is described in the filing from San Francisco. Guidewheel builds a cloud-based SaaS platform that connects to small, industry-standard IoT sensors on factory equipment to stream electrical and operational data into real-time monitoring and historical reports. Its software alerts plant managers and maintenance staff to issues, helping minimize equipment downtime and improve overall equipment effectiveness by roughly 10%–20% for some customers. Energy and carbon reductions are a consequential benefit as customers extract more production from existing assets rather than building new capacity. Pricing is sensor-based rather than per-seat, and the company aims for the system to pay for itself within the first month of use. Guidewheel was founded by CEO Lauren Dunford and co-founder Weston McBride, leveraging their manufacturing experience to target under-digitized plants. The company plans to use new funding to add features such as real-time scoreboards and throughput forecasting. Guidewheel (formerly known as Safi) is a San Francisco, CA–based manufacturing tech company founded out of Stanford University and led by CEO Lauren Dunford. It provides a cloud-powered FactoryOps platform that clips onto any machine on the factory floor to digitize operations and deliver real-time visibility. The plug-and-play solution is designed to reduce lost production and improve performance. The company has expanded quickly to 100+ plants across Mexico, East Africa, and the USA. Guidewheel has raised a total of $12M to date, including an $8M Series A. It intends to use the new funds to accelerate growth, expand operations, and broaden its business reach.

Leucine provides a digital twin of the pharma manufacturing shop floor, offering real-time performance monitoring, compliance management, and automated creation of electronic batch manufacturing records (eBMRs). Its platform uses proprietary LLM-based models to convert paper SOPs into digital workflows, enable root-cause analysis of deviations, and deliver actionable advice to improve efficiency. The company says it can onboard customers in about eight weeks and can reduce the digitization cycle of a batch from six-to-eight weeks to three-to-five days. Leucine monetizes via a tiered SaaS pricing model that scales with volume. The product is used by more than 30 companies across 300+ pharmaceutical manufacturing facilities in 10 countries, and Leucine reports 100% growth in facilities and a 300% increase in users over the last 12 months. Future plans include expanding the platform suite across the pharmaceutical manufacturing ecosystem and improving its AI co-pilot; the company also launched a beta of Leucine 10X, an AI framework that digitizes SOPs and creates dynamic production plans.
