Our Custom

Solutions team builds what our most demanding clients cannot get from the platform alone, and it runs out of capacity exactly when demand peaks. We are bringing in a freelance Solution Engineer for a 4 to 5 month mission to own custom data projects end-to-end through our busiest season. Concretely, you unlock projects we would otherwise have to turn down, with around 2 client projects delivered per month, from qualifying the need to presenting the results back to the client.

Your analyses feed the strategic decisions of retail, food & beverage, real estate and public sector leaders in France and Spain, on mobility data nobody else has. You also free up the team's senior capacity for our shift to Gini, our AI-powered product.
