They are creating a world where each and every person is empowered by using software to streamline and eliminate unnecessary tasks, and by using software to do what people have been unable to do until now. Conversation accounts for a large percentage of people's lives in society, and the concept of negotiation is not only used in business negotiations, but also in all aspects of human life, including romantic relationships. Yet, many aspects of conversations have not been given much opportunity to be reevaluated. amptalk presents such opportunities through developing software to create a world in which each individual is empowered and all users are happy.
