About us

What can you expect at freshcells?

Designing, developing, and maintaining e-commerce applications is our business. Cutting-edge technologies, customers who want more than average, and a fun, vibrant team of over 40 web experts aged 20 to 50+ from five countries – plus seven office dogs. We also have a stylish office and rec room on the spacious premises of a former carpet factory in the heart of Dusseldorf.
