There's nothing stopping you from creating extra folders under /app to contain various types of service objects. Personally I have: /app/factories - for classes which create active record objects /app/services - for classes which do something I generally don't care about the return value of. Often perfect for background jobs. /app/decorators - most of these are Draper classes /app/forms - form objects and a few others from various other gems.
