Swiss startup Yeastup has completed the commissioning of its production facility in Lyss, which transforms surplus brewer’s yeast into premium vegan ingredients. The facility has expanded its capacity to 4,000 liters of yeast per hour and will begin regular production at an industrial level in early 2026. Yeastup's patented process extracts Yeastin® and UpFiber® Beta-Glucan from brewer’s yeast, offering a sustainable alternative to animal and plant proteins with excellent nutritional properties.

Yeastup has invested 10 million Swiss francs in research and development, collaborating with the University of Applied Sciences Northwestern Switzerland. The company previously raised €9.47 million for facility repurposing and is now preparing for a Series A funding round. With production readiness achieved and strategic partnerships in place, Yeastup is focused on scaling, product development, and international market entry, inviting investors to participate in shaping the company's next stage of growth.
