Fin Aquatic Rentals is a functioning IoT-enabled surfboard rental service in San Diego with a live mobile app and hardware infrastructure. However, the project submission suffers from massive hyperbolic claims (e.g., 'most people have used my product') that contradict verifiable data (100+ downloads on Google Play since 2019). While the 'pay-by-the-minute' automated rental model demonstrates real-world utility and technical competence, the lack of significant traction after six years and the confusing financial metrics ('marketcap' listed as revenue) result in a low score.
