What the Stream knows about you
Sandbar, a startup of about fifteen people co-founded by CEO Mina Fahmi and CTO Kirak Hong, both formerly of Meta through its CTRL-Labs acquisition with Fahmi also ex-Magic Leap, is building Stream, an AI conversation-capture smart ring. The aluminum ring has a touch-sensitive top panel and a microphone that is off by default and proximity-tuned, so a wearer lifts a hand toward the face and whispers to record, with the audio transcribed to a companion iOS app that also offers conversational AI chat and media controls; it has no display, no camera, and no health sensors, explicitly distinguishing it from an Oura-style health ring. It is priced at $249 in silver and $299 in gold on pre-order with a $10-per-month Pro subscription, and the company has raised about $36 million, including a $23 million Series A in March 2026 led by Adjacent and Kindred Ventures after a $13 million round in November 2025. The registry records it at pilot and pre-commercial maturity as a deliberate cap-flag: as of mid-2026 it is pre-order only with a summer-2026 ship target and a sold-out first batch, funded and productized but not yet across the shipping line, so it is not classified commercial until general delivery is confirmed. On AI substance the entire product is an AI conversation-capture and assistant device rather than veneer on an audio gadget, but real-world AI quality is unverifiable because there are no independent reviews of shipping units, so all current claims trace to the company and launch coverage.

What it collects about you
The data this device picks up.
Recording you
The microphone only activates when you press and hold the touchpad. It is not always-on. The company makes money selling the product, not by selling your data. Data is encrypted at rest and in transit.
Your body data
Some user-generated data including voice and audio recordings may qualify as biometric data, covered by a separate Biometric Data Policy. The service is not intended for anyone under 18.
Where your data goes
Who else can see it once it leaves the device.
Training their AI
Sandbar uses aggregated and de-identified data to train its own AI models, and collects voice and audio recordings that may qualify as biometric data under a separate Biometric Data Policy.
Selling your data
Does not let outside companies use your personal info for their own commercial or marketing purposes, works only with trusted vendors under contract, and you can request access or deletion anytime.
