Overview

  • Zoho founder Sridhar Vembu says daily sign-ups spiked from about 3,000 to roughly 350,000 in three days, with teams working around the clock to scale infrastructure.
  • The company acknowledges onboarding bottlenecks such as delayed OTPs, slower contact sync, and occasional call issues, and says additional servers are being added within days.
  • Government visibility powered the surge after Union Education Minister Dharmendra Pradhan urged adoption of Indian-made apps and IT Minister Ashwini Vaishnaw spotlighted Zoho tools.
  • Arattai positions itself as privacy-first with end-to-end encryption on voice and video calls, while message-level encryption is still in development.
  • The app offers familiar messaging features with multi-device support, meetings and personal storage tools, but must convert downloads into daily use against WhatsApp’s entrenched user base in India.
