Sandbar Secures $23 Million Series A to Scale Private Voice Ring ‘Stream’ Ahead of 2026 Launch

New updates have been reported about Sandbar.

Sandbar has raised $23 million in Series A funding led by Adjacent and Kindred Ventures, lifting total capital to $36 million to accelerate development and hiring around its first product, Stream, a wearable private voice ring and conversational interface. The New York–based interface company will expand teams in machine learning, interaction design, and software as it targets a Summer 2026 commercial release following strong early interest and media coverage since Stream’s initial debut in November.

Stream combines a hardware ring featuring a touchpad, personal microphone, and haptic feedback with a conversational interface designed for on-the-go note capture, idea development, web retrieval, and task execution without requiring users to unlock a device or disrupt workflows. Unlike AI “companions,” Stream has no independent persona, activates only while a button is pressed, relies on multiple AI models for real-time organization and search, and keeps user data under the user’s control, with optional sharing to other apps. Co-founders Mina Fahmi (CEO) and Kirak Hong (CTO), who previously worked together at CTRL-labs prior to its acquisition by Meta, position Sandbar around “self extension” and human augmentation, and are preparing a closed beta this spring that will test software interactions and introduce Inner Voice, a personalized response voice feature, while pre-orders continue with the first batch sold out and the second slated to ship this summer.
