Sandbar, founded by former Meta employees Mina Fahmi and Kirak Hong, has raised $23 million in a Series A round led by Adjacent and Kindred Ventures, bringing total funding to $36 million and positioning the company to scale its AI-powered note-taking ring, Stream. The device, designed specifically for private, on-demand voice capture rather than health tracking, uses a proximity-tuned microphone activated via a touch panel, with early demand strong enough to sell out the first pre-order batch and drive a second release.
The company plans to begin shipping Stream this summer and will use the new capital to refine its app, build a web platform, cut AI response latency, and expand into multi-turn conversational workflows that can turn notes into actions. Sandbar, which currently employs 15 people with backgrounds at Amazon, Google, Apple, Fitbit, and others, intends to roughly double its software and machine learning teams and add marketing talent, while also exploring opening its companion app to users without the ring, expanding its addressable base in a competitive note-taking hardware market where form factor, privacy signaling, and usability are emerging as key differentiators.
