“The 40/60 team was able to immediately absorb our product philosophy to improve user journeys and produce mockups that we are gradually integrating into our application. The iterations were very fast; each time involving the right mix of ideas, concrete proposals and taking into account our feedback. More than a studio, 40/60 is a real partner for all design/product/UX themes with an ultra-dynamic, responsive and proactive team.”
