Now, a whole wave of wearables — rings especially — are betting people want to capture stray thoughts and ideas the same way. </p>
<p class="wp-block-paragraph">One of the companies chasing that bet is <a href="https://techcrunch.com/2025/11/05/former-meta-employees-launch-stream-a-smart-ring-that-takes-voice-notes-and-controls-music/" target="_blank" rel="noreferrer noopener">Sandbar</a>, the startup behind the private voice ring Stream, which has raised $36 million to date, including a <a href="https://techcrunch.com/2026/03/10/sandbar-secures-23m-series-a-for-its-ai-note-taking-ring/" target="_blank" rel="noreferrer noopener">$23 million Series A</a> led by Adjacent and Kindred Ventures. </p>
<p class="wp-block-paragraph">On this episode of TechCrunch’s<a href="https://techcrunch.com/podcasts/equity/" target="_blank" rel="noreferrer noopener"> Equity</a> podcast, Rebecca Bellan talks with Sandbar co-founder and CEO <a href="https://www.linkedin.com/in/mina-fahmi/" target="_blank" rel="noreferrer noopener nofollow">Mina Fahmi</a> about why he thinks so many voice hardware devices before Stream struggled to break through, and why he’s betting that keeping the human firmly in control is what it’ll take to get wearable tech right. </p>
