Nanolope raises €800k for thermal panels
Berlin startup Nanolope raised €800,000 to develop thermal energy storage panels for retrofitting buildings. The funding will scale production and launch pilot projects.
Berlin-based DeepTech startup Nanolope has closed an €800,000 pre-Seed financing round. The company, founded in 2025, develops patent-protected thermal energy storage materials for buildings.
The round was led by IBB Ventures through its pre-Seed Fund B#, with participation from several business angels and industry experts from the energy, real estate, and materials sectors. According to the startup, the building sector is one of Europe's largest energy consumers.
Nanolope claims its technology targets a critical challenge. Outdated heating systems and poor thermal performance in existing buildings lead to high costs and emissions. Comprehensive renovations are often too expensive and time-consuming for property owners.
The Core Technology
The company's solution is a ceiling panel that can turn walls, ceilings, and floors into passive thermal storage systems. These panels are designed for retrofitting without major structural work.
Dr. Felix Marske, CEO and co-founder of Nanolope, stated the company's focus. "The transition to sustainable heating will be decided in existing buildings," he said. "Many properties need solutions that can be retrofitted quickly and economically. That is exactly what we are developing with our thermal storage panels."
The company claims its panels lead to a more stable indoor climate. This reduces heating and cooling demand, lowers CO₂ emissions, and decreases peak energy loads.
Market Focus and Material Advantages
Nanolope states its solutions are aimed specifically at housing companies and operators of commercial properties like hotels, offices, and cafés. The goal is to improve energy efficiency and thermal comfort for occupants.
The company emphasizes its commitment to sustainable materials. It develops its storage panels in accordance with green chemistry principles. The panels are made from renewable, plant-based raw materials sourced in the EU. They are manufactured without rare earths and are recyclable.
Sabine Wolff, Principal at lead investor IBB Ventures, commented on the investment. "The team convinced us with its expertise, experience, and ambition to set new standards in the construction industry with its patented energy storage materials in the face of climate change," she said.
Use of Funds and Next Steps
The newly secured capital will be used for three primary purposes. Nanolope plans to scale production of its thermal energy storage systems. It will also implement initial pilot projects and expand its technical and commercial team.
The startup's founding team includes Dr. Felix Marske, Eric Matthes, and Dominik L. Schreiber, LL.M. Their stated aim is to make buildings more energy-efficient, climate-friendly, and economical through passive heat- and cold-storage systems.
