A mashup is a website that mixes components from other pages and, most importantly, Google maps. These aerial photos are enormously attractive to users because they are what most resembles the reality on the Internet today. Therefore, Alianzo uses Google Maps to complete all kinds of information and services, from a list of bars to the ratio of customers of a company geolocated at their homes. Since we did the first mashup in Spain, back in 2005, we have worked for Fon, ADN (Planeta), Starbucks (V2V), Mapalia or eitb.
