Through NNTB, students in schools and employees in companies can easily, safely, and anonymously report anything that bothers them.

In the case of schools, NNTB brings students and teachers together in a simple mobile and web app, giving students an anonymous way to speak up and seek help for themselves or their classmates, and enabling teachers to act before minor problems grow into something serious.

Companies can use NNTB as a whistleblowing platform to help maintain a corporate culture and create safer and better workplaces. Through NNTB, anyone in the company can anonymously report any problem or write suggestions to improve the current situation.
