About the company
Sandbar makes Stream, a finger ring that acts as a private voice interface for taking notes, chatting with an AI, and dictating text. To use it, you press the ring’s glass touchpad and speak; the built-in microphone listens only while pressed, with gestures to control notes, reminders, music, and more, and it can work with or without earbuds. It emphasizes privacy by avoiding wake words or always-on mics, uses a private mic and haptic feedback, and sells hardware direct to consumers rather than relying on personal data. Its goal is to be a private, hands-free extension of the mind that helps capture thoughts, memory, and ideas across iOS and Mac.

Simplify's Take
What believers are saying
- Sandbar raised $23 million on March 10, 2026, bringing total funding to $36 million.
- September 2026 preorder updates added MCP support, web search, reminders, and dictation.
- Preorders remain open at $249-$299, with Batch 3 shipping September 2026 and Batch 4 later.
What critics are saying
- Batch 1 and Batch 2 sold out, but shipping slipped from summer to fall 2026.
- Plaud, Omi, and transcribing earbuds already crowd Sandbar's note-capture niche.
- If Stream misses mainstream adoption, Sandbar becomes a capital-intensive gadget company with no platform lock-in.
What makes Sandbar unique
- Stream uses push-to-talk hardware, not always-on microphones, reducing privacy friction.
- Mina Fahmi and Kirak Hong bring Meta CTRL-Labs human-interface experience.
- Sandbar ships a custom ring with haptics, touch gestures, and iOS dictation.
