Sandbar's Voice Ring Stream Raises $23M Series A, Aims to Avoid AI Hardware Graveyard

Sandbar, the company behind the private voice ring Stream, has successfully secured $36 million in funding, which includes a $23 million Series A round led by Adjacent and Kindred Ventures. The startup aims to leverage voice-enabled wearables, particularly rings, to capture fleeting thoughts, aligning with the growing trend of AI notetaking devices like credit-card-sized gadgets, pendants, pins, and transcribing earbuds. Mina Fahmi, co-founder and CEO, explained on TechCrunch's Equity podcast the challenges faced by previous voice hardware and emphasized the importance of maintaining human control. He designed Stream to operate on a push-to-talk basis, prioritizing 'social acceptability.' Fahmi's experience at CTRL-labs, acquired by Meta in 2019, influenced his approach to human-driven input. Sandbar opted for custom hardware, a choice Fahmi described as 'gruelingly painful,' instead of modifying existing devices. He also discussed the necessary steps for voice wearables to transition from niche tech to mainstream adoption.
