League Hero is a mobile-responsive league management application developed by two designers and developers seeking an easy solution for managing leagues among friends. The creators, unable to allocate sufficient time for business development due to other project commitments, have decided to sell the application. League Hero monetizes by charging $1 per player in a league, with a provision for a 7-day trial to attract new users. Additional revenue can be generated through a feature allowing teams or players to pay league dues online, with a percentage fee collected using a payment platform. The application is built using the Ruby on Rails framework, hosted on a specific server provider, and integrates a payment processor for handling transactions. The sale includes several assets: the domain, application, payment processing credentials, social media accounts, and the code repository. The developers are committed to assisting buyers with the transfer of all these assets and ensuring the application remains operational. The developers emphasize the application's readiness for expansion, highlighting the need for someone with strong business development skills to grow the service. They are open to continued collaboration with the buyer to enhance the application post-purchase. The sale offers an opportunity for someone to take over a fully functioning and scalable league management platform, backed by support from the original creators.
