Reviewed on 7/16/2025

We hired Paul for the development of our MVP at Ekomia. The objective: to create a complete platform allowing our advisors (specializing in energy renovation of homes) to obtain all the necessary information (open data API, consumption analysis, ROI financial models...) to effectively support individuals in their projects, and to follow them at each stage of the process. Excellent collaboration with Paul throughout the project. He is very professional, responsive, and above all super flexible despite the numerous changes in direction due to the still low maturity of our project. He adapted to our budget and time objectives, and delivered a result that largely met expectations. Super communication, and we truly feel his involvement. A reliable partner with whom we continue to work. I recommend him without hesitation... but don't solicit him too much, we'd like him to keep some time for us!
