At Wiremind, our goal since we started in 2014 is to create optimization systems for the transport, logistics, sports and hospitality industries, without compromising on user experience. We build solutions that blend great design with cutting-edge technology to process vast quantities of data.

This leads us to work on many different kinds of projects: forecasting the demand for railway passengers between two major cities, handling millions of data points that we collect everyday through web-crawling, calculating the optimal way to fill an aircraft pallet with boxes of multiples dimensions and show the result in 3D, etc.

Our applications are used daily by users among the largest players of each industry (railway companies, airlines, etc.) in many countries and several continents. We are now a team of 30+, and growing about +100% every 18 months. Our business model is built on “software-as-a-service” solutions licensed through long-term contracts, allowing our strong growth to be based on strong profitability – without requiring any fundraising.
