Sandbar @sandbar Secures $23 Million Series A for its AI Note-Taking Ring.
Sandbar, an interface company based in NYC, led by Mina Fahmi, Kirak Hong @hokira, and the team, has raised $23 million in a Series A funding round led by Adjacent and Kindred Ventures @KindredVentures. The company’s smart ring is designed for note-taking rather than health tracking, unlike products from Oura. It features a microphone that is off by default and a touch-sensitive panel on top to record notes, interact with an AI assistant via the phone app, and control media playback and volume.

Currently Testing: Stream by @sandbar
My best thinking doesn't happen at my desk. It happens in the shower, while I'm doing my makeup, when I'm out to eat with a friend.
Lately I've been pulling out Granola and just talking to it. Strategies, insights, personal conversations, moments of inspiration, reminders.
It helps bring my subconscious into my work.
Marcus Moretti recently wrote on @every about how subconscious decisions define writing styles, which is a big reason LLMs can't write like you yet.
But here's the problem with just talking into Granola: it's not responding. It's not acting as an extension of me.
That's why I'm excited about Stream.
I can talk to it whenever and wherever. It captures my thinking but also acts as a thought partner.
It feels like @minafahmi and team are building really intentionally.
Congrats to the Sandbar team on the $23M Series A. Can't wait to keep testing.
If you're interested in this space, you can pre-order now.

If you are a designer that wants to be at a place that reveres design, @sandbar is the place for you
Mina Fahmi@minafahmi
Dear future teammate, I'm not a designer, yet I love design. Since we will build together, I'd like you to know what I believe. I believe design is part art, architecture, and mechanism. Art, because it must be beautiful. Architecture, because it requires a birds eye view. Mechanism, because it must be useful. You'll be responsible for a new interface: a conversational interface that feels like talking to yourself. It should be beautiful & useful, like thought. It should be made with a birds eye view, to span wherever you want to think. Our first product helps people capture thoughts & talk through ideas wherever they are. We have a lot more in store. The potential is sometimes dizzying, and always motivating. I feel the window of time we exist within. We have an opportunity to introduce a new relationship with technology—founded on extension over replacement. I'm thankful to have this opportunity, and to pursue it with many talented and caring people. I'm very excited to build towards it with you.

Many devices use off-the-shelf components. You can get to market faster, but your design is restricted
We wanted a custom design for many reasons:
⚬ Better ergonomics (tested over 100s of revisions)
⚬ Better input (glass touchpad w/ multiple gestures)
⚬ Better output (custom miniaturized haptics)
As a result, every Stream Ring is carved from a solid block of aluminum.

@DougStandley We're so excited for you to experience Stream, Doug! Thanks for the support.

I wrote about Sandbar, the NYC startup looking to ship an AI note-taking ring, Stream, this summer.
Part of what I found interesting about it is the wider race to try different form functions: earbuds, necklace, pin, wristband, now ring.
But part is also that Stream is meant to be fully single-player and non-invasive.
You raise your finger to talk to the ring in a conspicuous, les s surveillance-y way; Stream only listens to your voice, when you're actively tapping it, instead of being always-on.
Does that mean you won't get weird looks on the subway? I'm not sure -- and candidly not sure I'd use it every day. But the care that founder @minafahmi has put into the product's form and function makes me think they have a shot.

EXCLUSIVE: AI startup Sandbar has raised $23M in Series A funding for its note-taking smart ring, Stream, launching widely this summer.
I spoke to CEO Mina Fahmi (@minafahmi) about his vision for a voice interface for your thoughts -- and for working with AI agents.
"The thing that gets me excited is the promise of technology as an augmentation of the individual, that places the human in control,” he tells @UpstartsMediaCo.
