““Our scooter business was growing very fast – we quadrupled the size of our scooters fleet in Tallinn within a month. You can imagine the strain this puts on the back-office. Mooncascade helped us develop the Charger app – our scooters back-office and warehouse management app. Mooncascade team was proactive and put a lot of effort into quick onboarding, they even took the time to visit the warehouse to understand our real-life processes better. A friendly co-operation in every sense.”“
