# About Bifrost

Few foreigners use WeChat, and Facebook is not available in mainland China. Bifrost is the bridge between those two worlds.

## What Bifrost is

Bifrost (Bifrost: Global social on the App Store) is a cross-border social app developed and operated by Beijing Yanwan Technology Co., Ltd. People in China and people abroad are recommended to each other by country; when both light each other up within 12 hours they are connected one-to-one and can chat, with one-tap translation of messages and posts. The app also offers a seven-day journey with shared to-dos, a discovery community, group chats, a focus timer, and the Bifrost AI assistant.

## Why we built it

The two biggest social networks barely overlap. People in China are on WeChat, which has very few foreigners; the rest of the world is on Facebook, which is not accessible in mainland China. Someone in China who wants a foreign friend, and someone abroad who wants a Chinese friend, cannot find each other.

Bifrost puts both sides in one app. A **mutual light-up** replaces one-sided friend requests, so every connection starts with both people wanting it. **One-tap translation** lowers the language barrier. And a **seven-day journey** gives two new friends something to do together.

## Where the name comes from

Bifrost comes from Bifröst, the rainbow bridge between worlds in Norse mythology. It describes what the app is for: a bridge between people of different countries, languages, and cultures.
