About one.five
one.five is a German company that develops sustainable packaging solutions to replace single-use plastics for the consumer goods industry. Founded in Hamburg in 2020 by Martin Weber and Claire Hae-Min Gusko, the company's name is a reference to the Paris Agreement's goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels. Both founders gained relevant experience in the green-tech sector during their time at the vertical farming startup Infarm, where Weber was the CFO and Gusko was the Head of Business Strategy. They identified the challenge of finding sustainable packaging as a significant bottleneck for consumer brands.
Read full description
The company operates a materials-agnostic, AI-powered platform named Quartermaster, which acts as a packaging co-pilot. This platform scans material science patents and research globally to discover dormant intellectual property and innovative biomaterials. By using generative AI, one.five accelerates the research and development process, reducing the typically high failure rate and costs associated with creating new packaging. The system analyzes factors such as technical performance, regulatory compliance, and cost targets to engineer market-ready solutions. This approach enables the development of tailor-made packaging recipes for clients that balance performance, affordability, and sustainability.
one.five's business model involves identifying the needs of Fast-Moving Consumer Goods (FMCG) companies, developing customized packaging solutions, and then licensing the final recipe to packaging manufacturers for large-scale production. This allows clients to integrate the new solutions into their existing supply chains. The company's own 5,000 m² R&D campus near Hamburg includes facilities for algae cultivation, fermentation, prototyping, and testing, allowing them to scale technologies from concept to commercial viability. Their product range includes recyclable paper overwrappers and leakage-safe sachets for liquid food products. These materials are designed to be "litter-proof," meaning they can biodegrade in soil or marine environments if not recycled.
