The verified answer

As of Oct 2026, DEPLOY verifies Stream, a wearable by Sandbar (pilot): 1 verified deployment on record. 5 sources back the record.

Overview

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.

Notes

Verified: Sandbar (~15 employees; co-founders Mina Fahmi (CEO) + Kirak Hong (CTO), both ex-Meta via the CTRL-Labs acquisition; Fahmi also ex-Magic Leap) is building Stream, an AI conversation-capture smart ring. Raised ~$36M: $23M Series A (Mar 2026, Adjacent + Kindred) after a $13M round (Nov 2025, True/Upfront/Betaworks)., Maturity = pilot / pre-commercial (cap-flag): NOT shipping as of mid-2026: pre-order only, ship target summer 2026, first pre-order batch sold out. Funded + productized + hardware-defined (beyond pure research) but has NOT crossed the shipping line. Do not classify commercial until general delivery is confirmed., AI-substance: genuine premise, field-unverified: The entire product is an AI conversation-capture/assistant device (ambient capture -> transcription -> conversational AI), not AI veneer on an audio gadget. But real-world AI quality is unverifiable: there are NO independent reviews of shipping units; all claims trace to the company and launch coverage., Claimed but NOT verified: That it ships on schedule / at all (summer-2026 target, unshipped); transcription accuracy, latency, assistant quality (no independent hands-on); 'all-day battery'; real privacy behavior of the off-by-default proximity mic; the 'sold out first batch' figure (company-stated).

Specs

Stream: aluminum smart ring with a touch-sensitive top panel; microphone OFF by default and proximity-tuned (lift hand to face, whisper); records + transcribes to a companion iOS app; conversational AI chat + media controls. NO display, NO camera, NO health sensors (explicitly not an Oura-style health ring). $249 silver / $299 gold pre-order; Pro subscription $10/mo. Ships summer 2026 (target).
