Product vision

Basically all products that I have been involved in were initially made to solve a problem that one of us had. During my Master's studies, a friend and me needed a simulator for neural networks. Since there wasn't one available at that time, we wrote it. Today it is one of the most used open source simulators in its domain. Also the product that we are building now, is solving a problem that we have: how do you find the most relevant (science) news for your work?
