Sandbar is an AI hardware startup founded by ex-Meta engineers Mina Fahmi and Kirak Hong, building Stream — a smart ring with a microphone and onboard AI for ambient note-taking and voice-first agent interactions. The company raised a $23M Series A led by Adjacent and Kindred Ventures in late 2025, bringing total funding to $36M, with a thesis that voice + a ring is a more sustainable form factor than the screen-bearing AI pins and pendants that struggled in 2024-2025.
