Hamburg’s one.five lands €14 million to fix packaging’s product‑market‑fit gap
Hamburg-based startup one.five has raised €14 million in fresh funding to tackle one of the most persistent challenges in the packaging industry: aligning breakthrough sustainable materials with real-world product‑market fit. By combining materials science, data-driven testing and close collaboration with global brands, the company aims to accelerate the transition away from conventional plastics and poorly recyclable formats.
A new approach to sustainable packaging innovation
The packaging sector is under intense pressure. Brands must cut plastic waste, comply with tightening EU sustainability regulations, and satisfy consumers who increasingly demand low-impact products. Yet many “green” packaging concepts fail because they are too costly, incompatible with existing production lines, or deliver poor shelf life and product protection.
one.five positions itself as a bridge between early-stage material innovation and the stringent realities of industrial-scale packaging. Rather than simply supplying off-the-shelf solutions, the startup runs a data-led co-development process with brands, validating performance and economics from day one.
How one.five’s model works
From lab concept to scalable product
At the core of one.five is a platform that sources and develops novel bio-based, recyclable and compostable materials, then rigorously tests them against the requirements of specific products and markets. This includes:
- Screening promising innovations in biopolymers, fiber-based materials and advanced barrier coatings.
- Running mechanical, barrier and stability tests to ensure that packaging protects food, cosmetics or consumer goods effectively.
- Assessing compatibility with existing filling lines, printing technologies and logistics chains.
- Modeling cost structures and unit economics to ensure that new formats are commercially viable at scale.
This evidence-based process is designed to avoid a common pitfall: brands launching sustainable packaging pilots that cannot be scaled due to hidden technical or economic constraints.
Co-development with global brands
Instead of acting as a traditional packaging supplier, one.five works as a strategic partner. The company collaborates directly with brand owners, from R&D and procurement teams to sustainability and marketing departments, to design packaging that meets multiple objectives simultaneously:
- Lower carbon footprint and material usage.
- Compliance with Extended Producer Responsibility (EPR) schemes and upcoming EU packaging rules.
- Strong on-shelf presence and brand storytelling around sustainability.
- Robustness for global distribution networks.
By aligning stakeholders early and grounding decisions in data, one.five aims to shorten development cycles and reduce the risk of failed launches.
Funding to scale R&D and commercial footprint
The €14 million round will allow one.five to deepen its R&D capabilities, expand its network of industrial partners and strengthen its presence in key consumer markets. The startup plans to invest heavily in:
- Advanced materials testing labs for food, beverage, personal care and household products.
- Proprietary data platforms that track performance, recyclability and lifecycle impact across packaging formats.
- Scaling partnerships with converters, printers and manufacturers that can produce next-generation packaging at industrial volumes.
The funding underscores investor confidence in a new category of players that combine deep tech with hands-on industry expertise, rather than focusing solely on novel materials or purely digital solutions.
Why product‑market fit is so hard in packaging
Multiple constraints, one solution
Achieving product‑market fit in packaging is complex because each product category has highly specific needs. A snack manufacturer may prioritize oxygen barriers and shelf life, while a cosmetics brand may focus on premium aesthetics and reusability. Retailers, regulators and recyclers add further constraints.
Many sustainable concepts break down when they encounter:
- Unpredictable performance in real-world logistics, including humidity, temperature and mechanical stress.
- Limited availability of recycling infrastructure for new materials.
- Higher costs that brands cannot absorb in competitive markets.
- Consumer confusion about how to dispose of or reuse new formats.
one.five seeks to address these pain points by validating solutions against the entire value chain, from production to end-of-life, before brands commit to full-scale rollouts.
Data as a competitive advantage
A central element of the company’s strategy is the use of data analytics and structured testing protocols. By building a database of how different materials and structures behave under varying conditions, one.five can recommend configurations that are more likely to succeed in specific markets and distribution models.
This data-driven approach not only reduces risk for brand partners but also helps accelerate learning cycles across the industry, as insights from one project can inform others in adjacent categories.
Positioning within the global packaging landscape
The rise of players like one.five reflects a broader shift in the packaging ecosystem. Traditional suppliers are being challenged by startups that integrate materials science, software and sustainability strategy into a single service layer.
For established brands, partnering with such platforms offers a way to experiment with next-generation solutions without overburdening internal R&D teams. For regulators and environmental stakeholders, it creates a pathway for faster adoption of packaging that supports circular economy goals.
As more countries introduce strict targets on recyclability, reuse and waste reduction, the ability to rapidly test and scale compliant packaging will become a critical competitive advantage. With its new €14 million funding round, one.five is positioning itself as a key enabler of that transition, turning promising lab innovations into packaging formats that work in real markets, at real scale.
