Managing Director, DiscoEat & DIDIT
Looking at every single part of our product, marketing, operations and sales we were able to quickly highlight our strengths and weak points. Lumi helped put our thoughts together and opened our eyes to the huge opportunities we have ahead. We clearly defined the action plan and have started executing on it right away.
