Guesty, an AI platform for short-term rentals, has completed its acquisition of Smily, formerly BookingSync, a French property management system and channel manager. France has more than 1 million active listings and generated $9 billion in gross booking value through online travel agencies over the past year. Smily, founded by Sébastien Grosjean, brings technology and regional expertise dating to 2005, while its paid customer operations began in 2010. The companies will combine product, engineering and customer-support resources, and introduce Guesty’s AI capabilities and Agent Hub to Smily’s customers. Transaction terms were not disclosed, and all five Smily founders plus some shareholders are reinvesting part of their proceeds in Guesty equity.
