Company profile

researched Sep 2026

XO, formerly known as Rooit, is an anonymous social discovery and dating application. The product positions matching around "vibes" and shared interests rather than profile photos, pairing users through an AI-assisted matching layer and a set of interest-based community spaces.

The app is distributed on iOS and Android and also offers a web version that allows anonymous chat, browsing of community boards and purchase of Private Keys without downloading the app. In-app communities ("spaces") cover topics such as gaming, music, anime, fitness and food, alongside identity- and topic-based spaces including lesbian spaces, Gaytalk and Confession; some private spaces are gated behind invite codes.

Business model

The app is consumer-facing and free to download, with paid elements including a Premium tier and purchasable Private Keys that unlock access, sold both in-app and through the web version.

Monetization is indicated through a Premium offering and the sale of Private Keys via the app and website.

Traction

The company states the app has surpassed 1.5 million downloads, and lists in-app community spaces with member counts including anime (8.7k), music (5.1k), food (3.3k), gaming (2.4k) and fitness (1.2k).

Latest developments

Recent product additions described on the company's site include the rebrand from Rooit to XO, the AURA exposure-boost and XOXO token feature, X and Threads social verification, and a web version of the app.
