Arattai: India's Homegrown Messaging Revolution Takes On WhatsApp & Microsoft Teams

In a stunning display of grassroots tech adoption, Arattai—Zoho Corporation's homegrown instant messaging application—has catapulted from obscurity to India's most downloaded social networking app in September 2025. The app witnessed an unprecedented 100-fold increase in daily sign-ups, surging from approximately 3,000 to over 350,000 new users per day within just 72 hours, following powerful endorsements from India's top government ministers.

This explosive growth comes at a pivotal moment in India's technological journey, as the nation amplifies its Swadeshi (indigenous products) movement amid global trade tensions, particularly in response to Trump administration tariffs that have prompted India to double down on self-reliant technology platforms. The timing couldn't be more significant—as WhatsApp commands over 500 million users in India and Microsoft Teams dominates enterprise collaboration, Arattai emerges as a credible Indian alternative backed by government support and visionary leadership.
