- Sandbar has raised $36 million to date, including a $23 million Series A led by Adjacent and Kindred Ventures, to build its voice ring Stream.
- Mina Fahmi, Sandbar's co-founder and CEO, argued on TechCrunch's Equity podcast that prior voice hardware devices failed because they didn't keep the human firmly in control.
- AI notetaking hardware has proliferated in recent years across credit-card-sized devices, pendants, pins, and transcribing earbuds that capture meetings and produce summaries and action items.
- Stream is part of a newer wave of wearables — particularly rings — pursuing the capture of stray thoughts and ideas, not just structured meetings.
- The episode was hosted by Rebecca Bellan on TechCrunch's Equity podcast, where Fahmi laid out why he thinks a ring form factor and voice-first design can break through where others have not.
Why it matters: Sandbar's $36M raise shows investors are still willing to fund competing form factors in the AI wearables race, despite a crowded field of pendants, pins, and earbuds. Fahmi's pitch — that the failure of prior voice hardware was a control problem, not a technology problem — gives Stream a specific differentiation thesis to prove against roughly $36M of now-deployed capital.
