European family offices invest in one.five’s €14M Series A

one.five, a Hamburg-based company developing AI-powered solutions for packaging product development, has raised €14 million in Series A funding. The round was led by Dr. Hans Riegel Holding, the family office behind confectionery giant HARIBO, with participation from multiple family offices including Symbia VC (the Pfeifer family office) and KIMPA Impact (a Paris-based multi-family office). Additional investors in the round include 212 NexT, Btomorrow Ventures, and Zubi Capital, alongside existing investors Speedinvest, Planet A, Green Generation Fund, Climentum Capital, Revent, and WEPA Ventures. The company intends to use the funds to expand its proprietary AI platform and data foundation. Founded in 2020 by Martin Weber, former CFO of vertical indoor farming unicorn Infarm, and Claire Hae-Min Gusko, previously Head of Business Strategy at Infarm, one.five provides an AI-driven platform that supports the packaging supply chain by embedding product-market fit through material development. By translating technical performance, regulatory compliance, and consumer demand into data-driven requirement profiles, the company enables paper manufacturers, converters, and brands to eliminate R&D waste and accelerate time-to-market. The company currently works primarily with paper manufacturers including Starkraft, a business unit of Zellstoff Pöls AG (Austria), and Grünperga Papier (Germany), while actively partnering with packaging converters and global FMCG brands.
