It is appropriate for a small size company having less applications.
The tool is easy to install and have support for a lot of language. The app is smooth, fast and responsive. The mail notification about something going wrong or occurrences of errors is very cool.
There are a lot of better tools in the market when compared to Raygun which provide better features and support - Stackify, SEQ, Crashalytics.
