Sandbar’s Innovative Note-Taking Smart Ring Secures $23 Million in Series A Funding
Sandbar, a startup founded by former Meta employees Mina Fahmi and Kirak Hong, has recently made headlines with its smart ring, the Stream, designed specifically for efficient note-taking. Following a successful initial reveal, the company has secured $23 million in a Series A funding round, spearheaded by Adjacent and Kindred Ventures.
Unlike health-focused wearables such as Oura, Sandbar’s Stream ring is tailored for capturing notes. The device features a microphone that is deactivated by default, allowing users to activate it using a flat, touch-sensitive panel on the top. This setup enables users to record voice notes, interact with an AI assistant via a connected phone app, and manage media playback, such as adjusting volume or skipping tracks. The microphone is designed for close-proximity use, requiring users to lift their hand close to their face to record.
Fahmi, who boasts a background with innovative companies like CTRL-Labs and Magic Leap, shared that Sandbar has dedicated over two years to developing the Stream prior to its launch, refining it through tests with select users. The positive reception exceeded expectations, with many early adopters expressing eagerness to wear the ring daily. Early sales showed strong demand, prompting the company to release a second batch of preorders, as some users have reported using the ring over 50 times a day for various tasks.
The smart ring is expected to begin shipping this coming summer, with Sandbar prioritising enhancements to its app for a better user experience. They are also working on a web platform and plan to enhance user interaction with recorded notes. In the longer term, Sandbar aspires to create workflows that allow users to take actionable steps based on their notes.
Fahmi also highlighted the goal of integrating conversational capabilities into the app, aiming for dynamic interactions. The current setup encourages iterative exchanges, meaning users can continue discussing or clarifying notes rather than providing one-off commands.
While the app currently operates only with the Stream, there are considerations in place to allow broader access to non-ring users, enabling note-taking on the app even when the ring is being charged or misplaced.
With a team of 15 employees, many of whom hail from giants like Amazon and Google, Sandbar plans to use its latest funding to expand both its software and machine learning teams, as well as bolster marketing efforts.
The market for note-taking hardware is growing, with competitors like Plaud and Pebble entering the space, the latter planning a budget-friendly $75 ring. Notably, companies such as Taya are also exploring premium options designed as jewellery to broaden their appeal.
Investor Nico Wittenborn, who has a history of supporting voice-centric startups, believes Sandbar’s device stands apart from other note-taking tools. He appreciates the Stream’s form factor, suggesting that the action of lifting the hand embodies a discreet use case, distinguishing it from other devices that may record ambient conversations.
Having previously raised $13 million in funding, Sandbar has accumulated a total of $36 million to date with strong backing from True Ventures, Upfront Ventures, and Betaworks, signalling robust interest in its innovative approach to smart wearable technology.
