Value proposition

Reduces the 'time-to-market' for sustainable packaging by using AI to bridge the gap between lab-scale material science and industrial-scale manufacturing requirements.

Products and solutions

["AI Material Discovery Platform (matching market needs to material properties)","Technical Feasibility Assessment Engine","Sustainable Packaging Prototyping Services","Proprietary Biomaterial Database"]

Unique value

Acts as a 'system integrator' rather than a single-material producer; it uses AI to scan and evaluate thousands of global material innovations to find the perfect fit for specific commercial applications.

Target customer

Global FMCG (Fast-Moving Consumer Goods) brands, packaging converters, and material science researchers.

Industries served

["Packaging","Food & Beverage","Consumer Goods","Material Science","Chemicals"]

Technology advantage

Proprietary machine learning models that predict material performance (barrier properties, shelf-life, and machineability) on existing industrial equipment, bypassing years of traditional trial-and-error R&D.

How they differentiate

Acts as a 'system integrator' using AI to bridge the gap between lab-scale material science and industrial manufacturing. Unlike material producers, one.five uses machine learning to predict 'machineability'—ensuring sustainable materials work on existing factory lines without costly retrofitting.

Main competitors

["Citrine Informatics","Footprint","TIPA Corp"]

Key partnerships

["Dr. Hans Riegel Holding (Haribo)","Leading European Research Institutes (e.g., Fraunhofer)","Speedinvest and Planet A Ventures (Strategic Investors)","Global Packaging Converters"]

Notable customers

["Haribo (Strategic Partner)","Global FMCG Brands"]

Major milestones

["Founded in 2020 in Hamburg by Martin Weber and Claire Hae-Min Gusko","Raised €10.5M Seed round in 2022 to develop the AI discovery platform","Secured €14M Series A in January 2026 to scale the 'Product-Market Fit' solution for packaging"]

Growth metrics

Scaled team to 30-50 employees; developed a proprietary database of thousands of biomaterials; significantly reduced R&D time-to-market for sustainable packaging.

Market positioning

AI-driven material discovery and R&D platform for the circular economy

Geographic focus

Europe, North America

Patents and IP

Proprietary AI algorithms and data structures for material matching; specific IP related to material coating and transformation processes (often held in collaboration with research partners).
