Stream

Stream develops a private voice ring designed for capturing thoughts, building ideas, and managing communications through a wearable device. The ring enables push-to-talk functionality with silent haptic feedback confirmation, allowing users to capture notes, chat through ideas, and dictate across any application on iOS and Mac devices. The device features universal dictation with speech-to-text capabilities, a private microphone for whispering in any space, a glass touchpad for hold/tap/swipe controls, built-in haptics for silent feedback, an aluminum-resin body for lightweight comfort, and a custom curved battery for all-day use. Stream supports multiple use cases including capturing notes, reminders, todos, and lists; chatting through ideas with web and memory capabilities; and universal dictation across any app. The ring also enables users to resume and control music while keeping their phone in their pocket. The company positions the device as a self-extension for minds that keep moving, functioning as an inner dialogue and memory tool. Founded in 2025 and headquartered in New York, Stream has raised $36.0M in Series A funding from investors including True Ventures, Upfront Ventures, Betaworks, Adjacent, and Kindred Ventures.
