OUTCOME
Our clear design vision, strategic brand positioning, and agile product execution helped Cellstack gain early traction. We were accepted into the Technical University of Berlin’s startup program and secured €100,000 in funding from Norrsken Foundation, a leading Swedish non-profit that invests in climate tech. The project demonstrated how clear communication and thoughtful design can accelerate trust, unlock funding, and bring complex scientific innovation to market faster.
