Thibault Duchemin is looking to empower the over 400 million people who suffer from deafness and hearing loss with his mobile app, Ava. Ava is a listening software that connects the smartphones of participants of a conversation to create a real time transcript of the interaction. Duchemin envisions Ava being used in a variety of contexts, from boardroom discussions to dinnertime banter, situations that were previously inaccessible to people with hearing impairments. In the few months since its launch, Ava has amassed a user base of over 50,000. Evidently, Thibault Duchemin and Ava are changing the way the world hears.
