In the beginning of the 2000s, while I was still working for the small company I had cofounded, we decided to answer a Request for Proposal submitted by a waste removal company, for a system allowing to check whether all planned daily garbage collections had been performed. At this time, we didn't know a lot about the waste removal market. But we knew we were experienced enough in technologies we would have to assemble in order to answer the RFP: onboard equipment and embedded software, GNSS positioning, wireless communications, Geographical Information Systems, etc.
