Accel led a $140m Series C funding round in Commercetools, a commerce platform built on modern MACH principles. Previous investors Insight Partners and REWE Group also participated. “Our main focus is the retailer with more than $100m in gross merchandise value. This is when it becomes interesting. So we also sometimes have customers that start at $5m in GMV and quickly go to $50m. With that scale, they also have specific requirements, so the lines get a bit blurry," Dirk Hoerig, Commercetools CEO.
