First of all, congratulations for launching such a great product. While I was exploring Dropboard, I got the following questions/suggestions:-
1. If I'm not wrong, I read in one of your answers that the client's account can have unlimited members. Actually it's good and logical. But, why is the limit of 10 users imposed on the master account? It would be great if you can rethink this aspect.
2. The platform can be enhanced by adding stuff like categories, locations, departments, etc. Don't you think so?
3. When the candidate submits the application, an email is sent out for confirmation. My suggestion would be to white-label this as well. Few SaaS products asks you to add a DNS record and few send you an AWS link to verify the email after which the email is white-labelled. What do you think?
4. Will the Dropboard of my master account include the job postings of my clients? Is there any option to do so?
5. Do you plan to give a login credentials for the candidates to have a look at the status of the application? Would be nice.

Looking forward to hearing from you.
