Alcemy offers an AI-powered software platform that provides quality predictions across clinker production and at ready-mix concrete plants, delivering real-time insights along the entire value chain. Its algorithms enable producers to reduce clinker content step by step, with reported emissions reductions of up to 65 percent, while improving quality and lowering production costs. The company has demonstrated its solution in commercial settings, including a partnership with Spenner to produce a low-clinker, low-carbon cement mixture. Alcemy has also secured TITAN America as a customer and will deploy its quality-control software at a Titan cement plant in Florida. Founded in 2018 and based in Berlin, the startup plans to use new funding to continue research and development and to enter multiple new markets in 2024, including the United States. alcemy builds machine-learning and control-technology software that provides precise quality predictions for cement and concrete mixtures and their ingredients before shipping. The product enables manufacturers to counterbalance limestone and cement fluctuations, incorporate recycled ingredients safely, and produce higher-quality material at lower cost. The company says its solution can save up to 50% CO2 during production and that the startup and customers reduced 80,000 tonnes of CO2 in 2021. Founded in 2018 by Leopold Spenner and Dr. Robert Meyer, alcemy targets decarbonisation and regulatory compliance challenges in the cement and concrete industry. The startup will use the Series A proceeds to accelerate growth of its software development team and to build a sales team. alcemy positions its offering as a way to scale more sustainable cement and concrete production in a historically high-emission sector.

Founded in 2017, Berlin-based Enpal offers a fully integrated package for climate-neutral homes that bundles photovoltaic systems, battery storage, EV chargers, heat pumps, green electricity tariffs and a smart energy manager. Central to its model is a rental financing programme that removes the high upfront cost of hardware and connects customers to Enpal.One+, an AI platform that aggregates household batteries into a virtual power plant and trades excess electricity on the market. The company has installed more than 300,000 decentralised energy systems for over 100,000 customers, making it Europe’s largest residential solar installer and Germany’s leading independent metering point operator. Enpal has also become the country’s largest provider of installed heat pumps. Backed by investors such as TPG Rise Climate, SoftBank Vision Fund II and HV Capital, the firm continues to layer project-level financing on top of its equity base to scale rapidly. The new €700 million ABS warehouse and €600 million in senior bank loans deepen its capital stack and are intended to accelerate monthly household conversions to renewable energy. Enpal plans to leverage this capital efficient structure to expand further across Europe while reinforcing energy independence.

AMSilk develops advanced biomaterials from silk-based proteins using a patented technology platform and a supporting patent portfolio. It converts man-made proteins into formulations including fibers and yarns, hydrogels, and silk powder. The company’s high-performance materials target applications across the textile, homecare, biomedical, and automobile industries. AMSilk has collaborated with global companies and intends to continue partnering with enterprises worldwide. The company plans to use the new funds to build further commercial traction and to support the next phase of industrial scale-up to meet growing global demand. The raise followed an extension of its Series C financing in 2023. AMSilk produces bio-fabricated silk protein materials using a patented biotechnological process, converting plant-based renewable inputs into powders, hydrogels, fibers, and coatings. Its materials are 100% protein, do not involve natural farming processes, and are fully biodegradable under aerobic and marine conditions without generating microplastics. The company plans to use the new funding to accelerate industrial scale-up and expand commercial operations for its biotech materials. AMSilk raised an additional €25M in a Series C extension, bringing the total Series C to €54M. The extension was led by ATHOS (AT Newtec) with participation from Novo Holdings, Cargill, and MIG Capital. Since a €29M financing in 2021, AMSilk has invested in partnership agreements and supply contracts with leading apparel, medical, automotive, and biotech companies. AMSilk is an industrial supplier of synthetic silk biopolymers based in Planegg, near Munich, Germany. Its products are produced from plant-based raw material via bacterial fermentation and possess mechanical and biochemical properties suitable for multiple industries. The company offers high-performance Biosteel® fibers for textiles and industrial applications worldwide and cites use cases in medical devices and personal care products. AMSilk has announced collaborations and partnerships with brands like Adidas and Airbus. Led by CEO Ulrich Scherbel, the company plans to accelerate scale-up of its industrial projects and internationalize commercial activities to expand its customer base into new markets. It raised €29M in a Series C round to fund these efforts. AMSilk produces and processes SPIDERSILK biopolymers copied from the proteins of web-weaving spiders. These biopolymers enable new technical products and improvements to existing products. According to the company, the materials offer mechanical toughness, chemical resistance and biocompatibility while being completely biodegradable. AMSilk completed a €5m Series B financing and intends to use the capital to expand development and sales efforts for its first spider silk-based products. The company plans to pursue those efforts through partnerships with leading companies across major industries. Founded in 2008 as a spin-off from the Technische Universität München, AMSilk is led by Managing Director Axel Leimer.
