Innovation in real estate is taking a new turn with Yeswebook, a daring initiative by an entrepreneur who wants to revolutionize the management of deposits for his Airbnb properties. Despite a first tool developed on Bubble, the limitation of data management only within this platform quickly became an obstacle to the evolution of the service. The entrepreneur wanted more flexibility, dreaming of a custom back-end system that would allow him to extend his services beyond Bubble, especially for third-party applications like iOS and for tailor-made back-end functionalities. However, he was faced with the complexity of integrating existing data via a custom API, a task for which Fructu Agency was asked.
