Eight

Eight is a video‑first dating app that replaces traditional swiping and text‑based chats with short video introductions and live, time‑limited video calls between matches. Users create 30‑second video intros that are reviewed to help maintain genuineness, and then browse others’ videos within a fixed daily window. When two people “like” each other, they enter an 8‑minute live video conversation, after which they can choose to continue interacting or end the connection. The product focuses on enabling face‑to‑face interaction early in the match process, aiming to reduce superficial messaging and encourage more immediate, authentic exchanges.
