imo is a messaging application launched in 2007 by two former Google engineers, which has over 200 million active users. It focuses on labor migrants from the Global South, offering reliable video calling even on poor connections. The app grew organically as migrants shared it with their families and communities, particularly in regions with limited connectivity. imo has developed into a fully-featured messaging platform, serving as essential infrastructure for millions of migrant families to maintain connections. Its growth strategy involved avoiding direct competition in saturated markets and addressing the specific needs of migrant workers.
