Sandbar's AI Voice Ring Raises $36 Million for Market Expansion

Sandbar, creator of the voice-enabled AI ring Stream, raised $36 million in funding, including a $23 million Series A led by Adjacent and Kindred Ventures. The device captures voice notes and thoughts, converting them to summaries and action items through AI. The company argues that voice-based wearables avoid the common failure pattern of previous AI hardware by keeping users in control of their data and interactions, rather than having AI autonomously decide what to capture.
