Homadata is a real estate tech company dedicated to empowering consumers and businesses with data, insights and enlightenment around the place they call home. Located in the heart of the French capital, Homadata specialists collect, prepare, analyse and transform real estate, econometric, socio-demographic, tax, cadastral and environmental data in order to provide precise and objective decision-making tools for real estate transactions, negotiations, leasing and investment. The story of Homadata (aka. Bon de Visite) begins in 2015, with a simple vision: to impose transparency on the real estate market through data science. John-Guy Park, with 15 years of experience in large CAC 40 companies, decided to found Homadata. On this adventure he embarked a team of passionate people experienced in the latest technologies of Machine Learning and web development. Homadata and its data platform grew rapidly and met their market as soon as the beginning of 2016. The context of the digitalization of real estate and the evolution of increasingly digital practices and uses make the solutions developed by the start-up vital. Thanks to the solutions developed by Homadata, professionals and individuals can now rely on objective and complete information for their real estate decision-making. For 5 years now, we have been capitalizing on our unique geolocated data platform on the French market, a platform that is continuously being enhanced and updated in real time. Our main challenge is to innovate both in technology and in the use of real estate through the provision of our data, our algorithms, our modern UI and UX. Beyond the professional solutions we develop and market, we advocate for greater transparency of information in real estate, a rational use of new technologies based on data science and artificial intelligence.
