Grünperga Papier and Starkraft to accelerate market entry of new paper-based packaging portfolio with one.five’s packaging platform

Highlights:

• 4 x more efficient customer acquisition process
• 60% optimised R&D spend
• Calculated product-market-fit with AI
• Grünperga & Starkraft will expand their paper portfolio to include new paper packaging materials to meet the growing demand for sustainable packaging solutions in the market.

10 March 2026 - one.five, a Hamburg-based company building AI-powered solutions for packaging product development and market deployment, has successfully deployed its Product Market Fit Compass with Grünperga Papier GmbH, a European leader in translucent and crepe papers, and Starkraft, a business unit of heinzelpöls (Austria), one of the leading producers of high‑quality long‑fibre kraft pulp and kraft paper in Central and Eastern Europe. The tool analyses market, material, and machine data to predict the market success of the Grünperga or Starkraft paper portfolio. The AI-powered tool delivers customer acquisition four times faster than traditional processes and generates R&D cost savings of up to 60%. Both companies are using the Product Market Fit Compass to expand their paper portfolios with sustainable, paper-based packaging materials that can replace non-recyclable plastic films and multi-material composites. 

Incoming EU regulations, such as the EU’s Packaging and Packaging Waste Regulation, are putting pressure on the flexible packaging industry to replace non-recyclable materials. Entering new packaging segments requires in-depth market knowledge, technical validation, and supply chain partnerships.one.five's offering promises to accelerate speed to market readiness while also increasing the likelihood of product success. The Product Market Fit Compass predicts the performance of existing or new packaging material designs and evaluates whether this performance meets the needs of the end customer. This allows Grünperga and Starkraft to significantly reduce the time and effort required for customer acquisition.

“The Product Market Fit Compass acts as a co-pilot and builds a bridge between sales and R&D. It provides technical insights to enable a data-driven go-to-market strategy, helping our customers respond faster to shifting market expectations. The result is a shorter path to market and new packaging solutions that are sustainable and commercially viable,” said Martin Weber, Co-Founder of one.five.

"Our goal is to work closer with the end customer. We want to enable our partners with our new and improved paper portfolio. The Product Market Fit Compass has shown us where real demand for our products exists and where we have the highest odds of market success. This will allow us to streamline our sales efforts and collect the necessary learnings to understand what our long-term product roadmap can look like. The one.five platform enables us to compete and win deals against bigger players more effectively."  said Sébastien Schaal, CEO of Grünperga Papier GmbH. 

Maximilian Ortner, Business Unit Director of Starkraft, added: "As experts in kraft paper, we continue to advance our product portfolio and drive growth in this segment. The rapidly evolving flexible packaging market demands speed and precision — and one.five’s platform supports us in meeting these expectations while reinforcing our position in this dynamic and transforming market environment."

The Product Market Fit Compass is available as part of one.five's broader Quartermaster platform. Designed for all players in the packaging value chain, it helps users to reduce go-to-market risk while increasing speed and relevance.
