OPEN SOFTWARE TOOLS / APIs
One of the goals of HiReach is to provide useful software tools for start-ups involved in the Start-Up Lab, aiming at working in the transport poverty domain, that will be used in their own software as a support for their services. In this regard, an online repository was built, containing already existing open software tools / APIs, clustered around the functionalities they provide.
