Sesame AI is making waves as an audio-first, wearable AI platform designed to deliver high-quality, natural voice interactions—without relying on screens. As the world’s appetite for seamless, hands-free AI companions grows, Sesame’s approach stands out for its focus on voice presence and real-time, context-aware assistance. With the recent open-sourcing of its CSM-1B speech model and the viral popularity of its voice assistant “Maya,” Sesame is positioning itself as a game-changer in the AI productivity landscape.

Tool Background

Sesame AI was co-founded by Brendan Iribe (Oculus VR co-founder) and Ankit Kumar (former Discord engineering lead), both of whom bring deep expertise in hardware, AI, and large-scale consumer products. The company’s mission: to make AI-powered voice interaction as natural, intuitive, and emotionally resonant as human conversation.
