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
Quartermaster (Qt.Master) AI packaging co-pilot, Product Market Fit Compass, Hazelsun paper-based barrier packaging, Bluemorph high-barrier recyclable packaging, Glassleaf transparent bio-based recyclable packaging, AI material discovery / matching platform
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.

Major milestones
Founded in 2020 in Hamburg by Martin Weber and Claire Hae-Min Gusko, Raised €10.5M Seed round in Sep 2022 to develop the AI discovery platform, Introduced Bluemorph and Glassleaf packaging solutions in 2025, Secured €14M Series A in January 2026 led by Dr. Hans Riegel Holding (Haribo), March 2026: deployed Product Market Fit Compass with Grünperga and Starkraft; UPM Notes and Rawito/foodie & friends material launches
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).
