Selleo have developed our web application Metreno (http://www.metreno.com). They have done a remarkable job in delivering a great product to us. Working with the Selleo team has been characterized by good communication along the whole process. Before the programming started, they sought to have a clear understanding of the use and affordances of the web application. I believe this facilitated the process a great deal. Also during the development of the application, there has been close communication about the status and demonstrations, and suggestions have been followed up in an excellent manner.
We had an old system that was replaced. Already in milestone 1, this new system is better and more reliable than our old one. Selleo has proved to be a team of skilled and professional programmers. I can deeply recommend Selleo. They are professional, responsive and great people to work with. I will be happy to share my experience with others looking to use them for development.
