planetary announced it has raised $28 million in a combined equity and credit financing to expand its global fermentation platform and accelerate production of sustainable protein and food ingredients.
The round included 16 million CHF in equity and 6 million CHF in credit and was led by Radikal Capital and Oetker Ventures, with participation from Royal Cosun, Arc Investors, GGF, AgriFoodTech Venture Alliance, and existing investors including Astanor and XAnge. The financing brings the company’s total capital raised to nearly $40 million.
Planetary is focused on building a circular bioeconomy using fermentation technology to convert sugar and agricultural side streams into high-value ingredients such as mycoprotein, fiber, and enzymes. Its BioBlocks™ platform is designed to produce climate-resilient food inputs without reliance on traditional resource-intensive agriculture.
The company has already established industrial-scale production in Aarberg, Switzerland, demonstrating commercial viability with active revenue generation and product output. Its approach emphasizes cost competitiveness, with unit economics aimed at achieving parity or better relative to conventional protein sources.
The funding will support planetary’s global expansion strategy, including scaling its licensing model to enable localized production through partnerships, as well as launching new business-to-business mycoprotein products across Europe under its Libre brand.
The raise comes amid growing demand for sustainable and climate-resilient food systems, as companies and governments seek alternatives to traditional protein production that reduce environmental impact while maintaining affordability and scalability.
Planetary positions its fermentation-based platform as a solution to multiple structural challenges in the food system, including land use, water scarcity, and supply chain resilience, by transforming existing agricultural inputs into higher-value outputs.
