- Eqon
Participated · Seed · Jun 2026
Eqon develops a patented dimming solution intended to ensure precise heat delivery while significantly lowering energy consumption. The company says its technology can halve energy use in heating cables and cut CO2 emissions by more than 80 percent. Eqon positions the product as addressing infrastructure constraints and energy waste amid electrification of heating. The team develops the technology in Stavanger and targets both Norwegian and international markets. Management states the recent funding will be used to speed commercialisation and support rapid international expansion. The article does not disclose revenue, user metrics, founding year, or prior financings.
- Nature Robots
Participated · Seed · Mar 2026
Nature Robots develops AI-based modular autonomy software that enables agricultural machines and robots to navigate and operate autonomously across large fields, vegetable farming, viticulture, fruit growing, specialty crops, agri-photovoltaics, and agroforestry. The company positions its platform as a way for machinery manufacturers to deploy selected autonomy functions without building in-house stacks, and as a foundation for spot farming, decision support, and light agricultural machinery for soil conservation. Nature Robots says its technology can enable dramatic reductions in chemical inputs—up to 90% via approaches like laser weeding and spot farming—and cut CO2e emissions by up to 25% through AI-supported mission planning. Founded in January 2022 as a DFKI spin-off and based in the Agrotech Valley near Osnabrück, the company has received grants and equity funding including EXIST support and 2025 EIC awards. With the Seed proceeds, Nature Robots plans to grow its team, open a Munich office, and shorten integration timelines to scale deployments across customers’ fleets.
- one • fıve
Participated · Series A · Jan 2026
Headquartered in Hamburg, one.five offers an AI-driven solution that converts technical performance data, regulatory constraints, and consumer preferences into precise requirement profiles for new packaging materials. This data-centric approach is designed to cut R&D waste and shorten time-to-market for sustainable paper-based packaging. The company was founded by Martin Weber, former CFO of vertical-farming unicorn Infarm, and Claire Hae-Min Gusko. Early commercial traction includes collaborations with paper manufacturers Starkraft (a Zellstoff Pöls AG unit) and Grünperga Papier, while it is also cultivating partnerships with converters and global FMCG brands. The recently secured Series A funding will finance further platform development and international operational expansion. Although no revenue or user numbers were disclosed, the company positions itself as a critical technology layer within the packaging supply chain, aiming to deliver market-ready, regulation-compliant materials more efficiently.
- Rail-Flow
Participated · Series A · Dec 2025
Rail-Flow offers a cloud-based platform that functions as an ERP for the rail logistics ecosystem, digitising sales, procurement, contract management, order execution, transport management and invoicing. Complemented by a marketplace that connects shippers, operators, forwarders and railway undertakings, the software enables transparent procurement, faster bookings and improved network utilisation. The company is investing heavily in native AI to orchestrate workflows, anticipate decisions and automate routine tasks, thereby reducing manual work and improving data quality. New capital will be used to expand internationally through targeted market entries with local integrations and to bolster infrastructure for enterprise-scale deployments. Rail-Flow has consistently doubled its annual revenue in recent years, deepened intermodal capabilities via its merger with Simply Deliver and grown to a team of about 170 employees. Management positions the platform as a catalyst for shifting more freight to rail, addressing industry pressures around efficiency, labour shortages and sustainability.
- Enerin
Led · Series A · Nov 2025
Enerin is a technology company focused on replacing fossil-fuel industrial boilers with high-temperature heat pumps capable of delivering process heat up to 250 °C. Its flagship HoegTemp system is modular, flexible and able to integrate with existing industrial energy infrastructures while providing near-constant thermal output independent of waste-heat profiles and steam pressures. By installing an Enerin unit, an industrial site can avoid roughly 36,000 t of CO₂ emissions over the equipment’s lifetime, offering a meaningful pathway to lower carbon costs and meet decarbonization targets. The company positions its technology as filling the critical gap in sustainable steam and high-grade heat production, which today accounts for more than 20 % of global CO₂ emissions. Proceeds from the latest financing will be used to industrialize the product, scale manufacturing capacity and broaden the product range. Enerin has attracted a diverse set of European climate-tech and strategic investors through its multi-tranche Series A round, underscoring growing market demand for industrial heat electrification solutions.
