Sitters911 is a peer-to-peer app that connects parents in need of last-minute childcare with nearby babysitters. The app aims to solve the problem of parents' plans being cancelled when regular babysitters cancel at the last minute. It allows parents to find alternate sitters through online profiles that include reviews and verified documentation to build trust. The startup plans to test the app in a single city by developing user screening, payment features, and designing an intuitive interface to connect parents and sitters within a short timeframe.
