About us

Founded in 2015 in Athens, Greece, Welcome redefines the way people travel by going above and beyond the commoditized transfer service and being the first company to deliver a complete, personalised, in-destination travel experience. From the moment a traveler arrives at a new destination, until their return journey home, Welcome accommodates all their travel needs, including transfers, sightseeing trips, and local information, in the easiest, friendliest, and most personalised way possible. Welcome's drivers are experts in the area and share their local know-how to make travellers feel at home wherever they are. The company has also introduced contactless rides, thorough cleaning protocols, and protective equipment to make every journey safe.
