Rinckes, who said he has always lived in “well-mapped” places, was surprised to learn that in parts of the developing world, whole towns exist without any street names or traditional addresses. He began working through the quandary of how to effectively bring addresses to places without street names, and he started a side project to solve the problem that later turned into his full-time job.
