Since our launch, we have only been pushing Tuba to prospective organic customers so that we  can iteratively improve our product based on the feedback we get from the early adopters. Based  on the feedback from such users, as well as authors, narrators, and other stakeholders, we are 

currently working on ways to improve our user experience as well as broaden the library. Going  forward, we plan to reach the wider audience that we had initially set out to serve.
