Anton Ivanov, founder and CEO of DealCheck, transformed his experience as a real estate investor and junior front-end developer into a successful property analysis platform through the innovative use of Ionic, a hybrid mobile development framework. Initially frustrated with traditional Excel-based financial analysis methods for rental property investments, Ivanov identified the need for a more efficient solution and embarked on creating DealCheck in 2015, despite having no prior mobile app development experience. He chose Ionic for its reusable UI components, single code base for iOS and Android apps, and integration with Cordova plugins, allowing him to develop a functional MVP within four months. Following positive feedback from initial users, Ivanov continued refining the app, adding features like cloud storage and property data import, while also launching a web-based version using Angular. Over the years, DealCheck has grown to serve over 50,000 users worldwide, establishing itself as a leading tool in the real estate industry, and Ivanov attributes much of this success to the advantages provided by Ionic, which he plans to continue using as the platform expands.
