SpinLab launches 20th class with 10 startups tackling Energy, Construction and Health

SpinLab kicked off with its 20th cohort as an anniversary class. The new class comprises 10 startups working on solutions to challenges in the fields of energy, construction, circular economy and digital health. Over a period of six months, the teams are supported in the further development of their business models and in validating their solutions in the market. A key focus is on collaboration with established companies through the venture clienting approach, in which startups work with corporate partners at an early stage as technology providers to implement real-world use cases.

Here are the 10 new SpinLab Startups

biddingground is an independent B2B platform that makes corporate energy procurement digital and transparent. Commercial, industrial, and residential real estate companies can tender their energy demand and receive comparable, binding offers from vetted suppliers. Intelligent matching brings tenders and energy providers together in a targeted way, reducing effort and inefficiencies on both sides. The structured competitive process ensures market-based pricing and fair allocation.

HammerDrum has designed a novel drilling technology for horizontal drilling that addresses a key industry challenge: efficiently and economically drilling through hard rock. The solution uses conventional drilling fluid to generate a powerful percussive effect, without the need for additional equipment such as compressors or special pumps. This enables drilling companies to work significantly faster while using substantially less drilling fluid.

Hydroyal is working on key components for the cost-effective and scalable production of green hydrogen. The company manufactures innovative membranes for electrolyzers that do not rely on expensive precious metals and are made from readily available materials. An industrially scalable manufacturing process enables efficient and resource-saving production. The technology reduces costs, lowers dependence on scarce raw materials, and improves the recyclability of electrolyzers.

KauSchlau offers a digital self-therapy app for people suffering from teeth grinding (bruxism) and related temporomandibular joint disorders. The app provides a personalized, evidence-based exercise program that adapts to users’ progress using computer vision and short questionnaires. Live AR feedback accompanies massage, stretching, strengthening, and relaxation exercises to support correct execution. A digital pain diary helps users identify individual triggers and track progress.

Navou converts vacant buildings into modern, affordable housing in a fast and reliable manner. Properties are comprehensively refurbished and equipped with a proprietary, sustainable construction system that makes conversions significantly cheaper and faster than conventional renovations. The highly standardized approach substantially reduces time and cost risks. At the same time, a digital assessment process allows the suitability and economic potential of a building to be evaluated even before acquisition. In this way, Navou provides an efficient solution for reducing vacancy and creating new housing in a resource-efficient manner.

FiberFlow has developed a process technology that mechanically separates mixed textile waste into its individual fiber components for the first time. This addresses a central obstacle in textile recycling: many textiles consist of inseparable material blends and therefore cannot currently be recycled. FiberFlow’s technology makes these fiber blends sortable and creates high-quality raw materials for further processing. As a result, recycling processes can be implemented at industrial scale for the first time, keeping large volumes of textiles that were previously incinerated or landfilled within the circular economy.

levelbuild provides a no-code platform that significantly reduces digital complexity in the construction industry. Many companies currently work with a patchwork of legacy systems, isolated solutions, and Excel files—a situation that leads to errors and high costs. Instead of replacing existing systems, levelbuild integrates them into a central, reliable data source that employees in all roles can access in real time. This allows companies to map their processes without programming, reduce software costs, and digitize step by step.

VON KAI has developed a voice-based AI companion that provides everyday companionship for older people in Germany and promotes social participation. The solution deliberately relies on landline telephones and enables natural, empathetic conversations without apps, screens, or technical barriers. The underlying voice-to-voice AI is GDPR-compliant, specialized in the German language, and designed for trustworthy communication.

Points2BIM uses an AI-based solution to automatically convert building scans into precise digital building models compliant with BIM standards. This replaces time-consuming manual modeling processes that often take weeks and incur high costs, particularly for existing buildings. With Points2BIM’s technology, digital building models can be created up to 90 percent faster and implemented at scale for the first time. Owners of large real estate portfolios gain a reliable digital foundation for planning, renovation, and operations.

nextract energy operates an intelligent energy management system for controlling large-scale storage solutions such as batteries and electrolyzers at wind and solar parks. The software optimizes system operation in real time and significantly reduces curtailment losses caused by grid constraints. By intelligently coordinating generation, storage, and market prices, operators can use their assets more efficiently and generate additional revenue. The system integrates technical asset data, grid connections, weather forecasts, and market signals in a manufacturer-independent model.
