Currently I'm developing an AirBnb like website/app for wine. I'm looking forward to explore more ideas. I've manged to collect a few ideas that I'll list in the following, but I'm curious what other people have in mind. My current programming capabilities are ruby on rails, python, react, redux, ionic... Some ideas for AirBnb derivatives: - Marketplace for winemakers to sell their wine. (Current Project) - Marketplace for elderly people who need 24/7 care. - Marketplace to rent out space likes warehouses (B2B only) - Marketplace to rent out construction tools (B2B only) Other website/app clones I'm able to reproduce Fiverr Marketplace - Currently no ideas Etsy Marketplace - Currently no ideas Uber - Currently no ideas Uber Eats - An on demand E-Courier app (similar to glovo) I'm looking forward to your comments.
