Sandbar Secures $23M: Stream Smart Ring Redefines AI Wearables
March 11, 2026, 10:27 am
Sandbar, a New York City-based technology firm, has closed a $23 million Series A funding round. This brings its total capital raised to $36 million. The company aims to redefine wearable artificial intelligence with its Stream smart ring. The device offers a discrete, voice-activated interface. It enables seamless thought capture, real-time web interaction, and AI assistance. Co-founders Mina Fahmi and Kirak Hong, both former Meta experts, champion a vision of "self-augmentation." They integrate AI as an extension of human thought, prioritizing privacy and efficiency over an AI companion. This significant investment fuels team expansion, advanced software development, and the Stream ring's anticipated summer 2026 shipment. Sandbar strategically positions itself at the forefront of the rapidly expanding AI wearable market, promising to reshape daily human-machine interaction.
Sandbar, an innovative AI wearable company, recently secured $23 million in Series A funding. This substantial investment, led by Adjacent and Kindred Ventures, pushes Sandbar's total funding to $36 million. The New York City startup readies its flagship product, the Stream smart ring, for a summer 2026 launch. This device promises to transform human interaction with artificial intelligence.
The Stream ring represents a new generation of personal AI interfaces. It is a sleek, voice-responsive device. Users can capture ideas, organize thoughts, and access web information effortlessly. Its design emphasizes convenience and discretion. The ring integrates a touchpad, a personal microphone, and haptic feedback. This allows interaction without needing to access a smartphone.
Mina Fahmi, Sandbar's CEO, co-founded the company with Kirak Hong, CTO. Both bring extensive experience from human-computer interaction. They previously collaborated at CTRL-Labs, a neural interface startup acquired by Meta. Their shared background focused on bridging human intent with digital action. Fahmi also worked at Kernel and Magic Leap. Hong contributed his expertise at Google. This deep expertise underpins Sandbar's innovative approach.
The founders envisioned an AI that augments human thinking. They aimed for an extension of the mind, not a replacement or a companion. This philosophy shaped the Stream ring's development. It functions as a private voice interface. The system activates only when a button is pressed and the user speaks, even at a whisper. This ensures user privacy. The device uses multiple AI models to organize information and respond conversationally. It also searches the web in real time. User data remains private. Sharing with other applications occurs only at the user's discretion.
Stream is a tool for "self-augmentation." It helps users think, remember, and act more efficiently. The interface lacks its own identity. It focuses purely on utility. This design choice differentiates Stream from other conversational AIs. It provides a seamless, friction-free way to interact with technology. The ring can pick up whispers even in noisy environments. This ensures thoughts are captured accurately.
Pre-orders for the Stream ring are currently open. It is available in silver ($249) and gold ($299). Initial batches have already sold out. Shipments will commence this summer. A free three-month trial of Stream Pro is included. This optional subscription costs $10 per month and unlocks unlimited notes and chats. No mandatory subscription exists.
The new funding will fuel significant expansion. Sandbar plans to grow its 15-person team. New hires will focus on machine learning and software development. Leadership hires include Sam Bowen (VP of Hardware) and Brooke Travis (VP of Marketing). These additions bring experience from major consumer hardware products like the iPhone, Vision Pro, Fitbit, and Kindle.
Sandbar's future vision extends beyond memory aid. The company aims to evolve Stream into an agentic AI tool. This means the ring could eventually take actions on a user's behalf. It could distribute work or manage tasks. This ambitious goal positions Sandbar at the cutting edge of AI development. It promises an even more integrated digital assistant.
The timing of Sandbar's debut is significant. The AI wearables market experiences a surge of investor interest. Historically, this segment attracted minimal venture funding. That trend is rapidly reversing. Finnish smart ring maker Oura raised $900 million at an $11 billion valuation. Dubai-based Xpanceo secured $250 million for smart contact lenses, valuing it at $1.35 billion. These figures highlight growing confidence in the sector.
Major technology companies also recognize this shift. Meta advances its smart glasses partnership with EssilorLuxottica. It also acquired AI pendant maker Limitless in 2025. Amazon purchased Bee, known for its AI-enhanced bracelets. OpenAI reportedly collaborates with famed Apple designer Jony Ive on a secretive wearables project. This broad industry activity underscores the burgeoning potential.
Sandbar addresses a critical need. AI capabilities are immense, but their integration into daily life often feels cumbersome. The Stream ring seeks to provide a natural, intuitive interface. It aims to maximize the utility of AI in an unobtrusive way. This focus on seamless integration could unlock AI's full potential for everyday users. Sandbar stands ready to lead this charge. Its Stream smart ring offers a compelling vision for the future of wearable AI.
