Sesame Company Development

Voice Companions Before Eyewear

Sesame put its conversational work into a mobile beta, where people could try extended spoken interactions. The company has also discussed smart eyewear, which would give the companion a different point of access than opening an app.

Sesame Competitive Landscape

A Conversation with No Menu

Tree-based voice interfaces guide callers through a defined transaction. Sesame's companion aims at ongoing, open-ended exchanges, where pacing and the ability to recover from an interruption are part of the experience.
