In July 2026, FERMOTEIN® became the first whole-food mycelium ingredient authorised under the EU Novel Food Regulation. Proving the science took six years. Producing it reliably, efficiently and at industrial scale is the part still being figured out, and it is the part you would work on.

Who we are

The Protein Brewery is a Dutch food technology company based in Breda. We produce FERMOTEIN®, a whole-food mycelium ingredient made through biomass fermentation, delivering complete protein, fibre and a range of micronutrients from a single, minimally processed source. It goes into active nutrition, better-for-you bakery, snacks and dairy alternatives. Founded in 2020, we operate an FSSC 22000 certified production facility with two 85,000L fermenters and have raised more than €70 million to scale it. Our team of around 45 people is growing. We are a mission-driven organisation, which for us means the purpose of the company, the teams and the individuals in them point the same way. Four values describe how we work.

​

SHARING the same purpose. Working together as one team in our pursuit to reach our mission and have a positive and lasting impact on the world around us and beyond, while having fun.

DARING to do what no one did before and encouraging whoever dares to do so. Creating a stimulating environment where people feel free to innovate in a pragmatic way. Enabling us to remain agile and to move ahead speedily.

TRUSTING each other’s capacities, intentions and sense of responsibility, leading to a culture of ownership, undivided responsibility and relentless dedication.

CARING for each other and your work environment. Supporting each other, professionally and personally. Valuing each team member as the person he or she is, regardless of background, capacities or status.
