Sandbar Secures $23 Million to Innovate Wearable Conversational Interfaces

Sandbar's Ambitious Leap into Wearable Tech

In the fast-paced world of technology, Sandbar, a trailblazing interface company located in the heart of New York City, has made headlines with their recent achievement of securing $23 million through a Series A funding round. This financial boost, led by Adjacent and Kindred Ventures, represents a significant step forward, bringing the total funding for the company to an impressive $36 million. This round follows an earlier $10 million Seed round spearheaded by True Ventures in early 2025 and a preceding $3 million pre-seed round led by Upfront Ventures and Betaworks in early 2024.

In November 2025, Sandbar premiered their groundbreaking product, Stream, which is more than just a gadget; it's a private voice ring coupled with a conversational interface crafted to elevate human-computer interaction. With remarkable reception and media attention from outlets such as The Wall Street Journal and Wired, Stream aims to redefine the way individuals engage with technology by prioritizing personal augmentation over mere functionality.

As co-founders Mina Fahmi (CEO) and Kirak Hong (CTO) note, the philosophy driving Sandbar's innovations is based on self-extension—creating tools that augment human capabilities rather than replace them entirely. The duo previously collaborated at CTRL-labs, a venture acquired by Meta in 2019, where they focused on merging human intent with technological action. At Sandbar, they lead a team of passionate engineers and designers committed to enhancing how humans think, remember, and create in day-to-day life.

According to Fahmi, "We believe in self-augmentation in an agentic world. With the right interface, everyone should be able to develop ideas and get things done wherever they are, with the speed, privacy, and ease of thinking." This vision comes to life with Stream, which combines a discreet voice ring that features a touchpad, personal mic, and haptic feedback with an advanced conversational interface. Users can easily capture notes, brainstorm ideas, retrieve information, and take actions on-the-go without the constant need to unlock their devices.

A key advantage of Stream is its distinct design, which intentionally avoids establishing an independent identity for the interface. Instead, it remembers user inputs and only listens when the button is pressed. By leveraging multiple AI models, Stream organizes, responds, and performs web searches instantly, ensuring users' data remains private and can be integrated with other applications. Furthermore, this spring, Sandbar plans to initiate a closed beta to refine software interactions and unveil 'Inner Voice,' a personalized response feature that enhances user experience through a tailored auditory interaction.

The team behind Sandbar comprises 15 dedicated individuals who have previously developed products for notable brands, including iPhone and Fitbit. They are bolstered by key hires such as Sam Bowen, previously excelling at Amazon and Fitbit, and Brooke Travis, who has an impressive background in marketing for Equinox and Dior.

As demand for Stream grows, pre-orders are now open at sandbar.com, offering early pricing opportunities. Following the success of Batch 1 pre-orders, which quickly sold out, Batch 2 is now available with expectations set for shipping in Summer 2026.

Sandbar's mission is clear: to disrupt conventional interactions between humans and technology, propelling us toward a future where individuals showcase their fullest potential through innovative interfaces. As they continue to build momentum in the tech landscape, the significance of their approach to wearable technology cannot be overstated, signaling a transformative era where personal enhancement and ease of access are paramount.
