We have an idea for a cross platform app (Android/iOS) which is basically a food marketplace app in major cities.
Some of the features we'd like to include in the MVP are:
1. Customer account signup - using social/google account
2. Supplier signup and verification
3. Search by cuisine and keywords
4. Location awareness - people offering services around you
5. Review system
6. Ability to plugin a payment gateway
The above list is by no means exhaustive but covers the major aspects. A brief can be provided for a more detailed look and NDA being signed.
