Sandbar's Stream ring, a $249 AI-powered wearable with a push-to-talk voice interface, sold through its first three preorder batches after launching last November. But customers waiting for their devices will need more patience than the company initially suggested. The startup's shop page showed as of mid-August that shipments have slipped from a Summer 2026 target to Fall 2026.
The delay comes as Sandbar tries to carve out a niche in the increasingly crowded market for AI wearables, where startups are racing to build the next essential interface for conversational AI. CEO Mina Fahmi framed the device as fundamental infrastructure. "We think of this as the mouse for voice," he told WIRED at launch.
That comparison signals the company's larger ambition. Stream isn't trying to be another health tracker or step counter. Instead, the aluminum-and-resin ring, designed to sit on the index finger, focuses squarely on productivity. It pairs with iOS and Mac software to handle voice notes, dictation across any application, chat functions, reminders, timers, and media playback controls.
The interaction model centers on a glass touchpad: hold to speak, tap to interrupt, swipe to adjust volume. Haptic feedback confirms when the microphone activates. Rather than storing raw audio, the device transcribes speech to text on the fly, according to coverage by Wareable in November. Sandbar added what it calls "Universal Dictation" in a July product update, letting users dictate text across iOS and Mac without switching apps, Fahmi noted on LinkedIn.
One feature stands out for its personalization. The system's "Inner Voice" responds in audio that mirrors the user's own speech patterns, according to the shop page. Users can tweak, delete, or switch to a generic voice if the personalized version feels unsettling. The ring functions with or without earbuds; audio plays through connected devices when available, while haptics provide silent feedback otherwise. Some capabilities work offline, keeping notes accessible without an internet connection.
Fahmi and CTO Kirak Hong bring deep experience in neural interfaces. The pair worked together at CTRL-labs, the startup Meta acquired in 2019. Fahmi's resume includes time at Kernel and Magic Leap, MIT research, and a 2025 Nature paper on neuromotor interfaces. Hong holds a computer science PhD from Georgia Tech and spent time at Google before joining CTRL-labs.
By the time Sandbar announced its Series A in March, the New York–based company had grown to 15 employees, TechCrunch reported then. The same month brought two senior hires: Sam Bowen as VP of hardware, previously leading product at Amazon, Fitbit, and Peloton, and Brooke Travis as VP of marketing from Equinox, Dior, and Gap, according to a PR Newswire release.
Pricing remains consistent with launch figures. The silver ring sits at $249 on the shop page, with a crossed-out $349 suggesting a discount, while the gold version costs $299. Those numbers match what WIRED and Tom's Guide reported in November. Batch 4 preorders now ship in Fall 2026 to U.S. customers only, a notable pushback from the Summer timeline the company cited in March press materials and May legal filings.
Core features like notes, music controls, and limited weekly dictation require no subscription. But preorder customers get a three-month trial of a $10-per-month "Data Plan," the shop's FAQ explains. The device supports iOS at launch, with no Android timeline announced. International shipping remains off the table for now.
Funding came quickly once the company showed traction. Sandbar closed a $23 million Series A in March, co-led by Adjacent and Kindred Ventures. That brought total capital raised to $36 million. True Ventures led a $10 million seed round in early 2025, while Upfront Ventures and Betaworks co-led a $3 million pre-seed in early 2024. Wilson Sonsini advised on the Series A, according to a firm document from May.
"The response was a lot warmer than we expected," Fahmi told TechCrunch in March, discussing early preorder demand. At the time, Sandbar said it was hiring across software, machine learning, and marketing roles to hit the Summer shipment goal.
Stream lands in a packed field. TechCrunch's March coverage named Plaud and Omi card-style recorders, Friend and Limitless pendants, Taya's premium necklace, and the budget Pebble ring as competitors in the voice-note category. Launch articles in November frequently invoked Humane's AI Pin and Amazon's Bee wristband. Health-focused rings from Oura and Samsung occupy a different lane entirely. Engadget and Wareable both emphasized Stream's productivity-first positioning over biometric tracking.
Privacy gets prominent billing in Sandbar's messaging. "We make revenue from selling products, not from selling your personal information," the shop FAQ states. The microphone only listens while the touchpad is pressed. Users can access and edit all stored data. The ring transcribes speech to text rather than recording audio files, sidestepping some privacy concerns around persistent voice capture.
The company runs a Developer Alpha program, exploring how external builders might use the ring's hardware and software for agents, memory systems, and data integrations, its site showed Wednesday.
"I really never wanted technology to replace people... an extension of my own thinking," Fahmi told Observer in March, sketching out his vision for conversational AI as augmentation rather than replacement. Sandbar, founded in 2023, describes its mission as building "self extension" tools for what it calls an "agentic world." Whether customers will wait until Fall to find out if that vision translates to a useful product remains the more immediate question.
