Hamburg-based startup ValueGrain has closed a €3.3 million seed financing round to expand its technology for turning brewers spent grain into plant-based food ingredients.

The round includes up to €3 million from Bernhard Schadeberg, managing partner of the Krombacher Group, alongside a €300,000 follow-on investment from Joachim Friedsch, owner of Fristam Pumpen KG. The company said the funding comes at a post-money valuation of €10.3 million.

ValueGrain develops upcycling technology that uses brewers spent grain, a by-product of the brewing process, to produce nutritious and price-competitive ingredients for food manufacturing. The new capital will be used to grow the team, expand R&D, prepare the product for additional food applications, and build scalable logistics capabilities.

The investment highlights continued investor interest in circular food production and industrial uses for by-products from established supply chains.
