Sandbar Raises $23 Million for Its AI Note-Taking Ring

Sandbar, a tech startup founded by Mina Fahmi and Kirak Hong, former Meta employees, has recently caught the industry's attention with its innovative device, the Stream ring. This product, which generated significant interest last year during its unveiling, has enabled Sandbar to raise $23 million in a Series A funding round led by Adjacent and Kindred Ventures.

The Stream ring stands out for its note-taking capabilities, positioning itself in a different niche than health rings like those from Oura. Equipped with a microphone that remains inactive by default, the ring activates via a touch panel located on its top. This device not only allows users to record notes but also to interact with an AI assistant through a dedicated mobile app, and to manage multimedia commands such as play, pause, track change, and volume adjustment.

Notably, the ring's microphone is designed to capture sounds in immediate proximity, which means users need to bring their hand close to their face to record notes.

A Project Years in the Making

Mina Fahmi, who has also worked for startups like CTRL-Labs and Magic Leap, explained that the development of the ring began over two years ago. After a testing phase with friends and early users, Sandbar officially unveiled its product last year. Fahmi shared with TechCrunch that the public reception has been more positive than expected, which has been a significant source of motivation for the team. "Many people have expressed interest in wearing this ring," he revealed.

The startup saw strong demand right from the launch, with the first batch of preorders selling out in record time, prompting Sandbar to open a second batch to meet the enthusiasm. Some users utilize the ring more than 50 times a day to organize presentations, trips, or meals.

Aiming for Commercial Launch This Summer

Sandbar plans to begin shipping its smart ring this summer. The company is currently focused on enhancing the user experience of its app, working on a web platform, optimizing the user interface, and reducing the latency of responses from its AI model. In the long term, Sandbar aims to develop more autonomous workflows, allowing users to leverage their notes proactively.

Fahmi also emphasized the importance of conversational exchanges in the product's evolution. Many users ask the AI assistant questions about unrecorded notes, prompting Sandbar to integrate more dynamic interactions. "We believe that interactive conversation is essential," he stated, adding that the Stream ring is particularly effective for iterative tasks that start with a simple conversation or note editing.

A Mobile App in Evolution

Currently, Sandbar's mobile app works exclusively with the Stream ring, but the company plans to expand access to users without the ring. The app can be used independently to take notes when the ring is charging or misplaced.

Sandbar currently employs 15 people, who have previously worked for giants like Amazon, Fitbit, Equinox, Google, and Apple. With the new funding, the company plans to double its software development and machine learning teams, as well as strengthen its marketing team.

A Growing Market

The note-taking device sector is booming. Companies like Plaud are developing devices for taking notes during meetings, while Pebble plans to launch a $75 ring this year. Other startups, such as Taya, are taking a high-end approach by designing their products as jewelry to appeal to a broader audience.

Nico Wittenborn from Adjacent, who has invested in voice-focused startups like Blinkist, believes that Sandbar's Stream ring offers a more suitable format than other note-taking devices. The gesture of raising a hand to take a note signals an intention for private use, unlike other devices that might record surrounding conversations.

Wittenborn also points out that some existing devices only target a narrow audience, often referred to as "tech bros," while Sandbar's format could encourage broader adoption.

Before this funding round, Sandbar had already raised $13 million from True Ventures last November, bringing the total funds raised to $36 million.
