Overview

• Zoho’s Arattai hit the top of app-store social charts after a surge in sign-ups driven by high-profile endorsements and social media buzz.
• Zoho acknowledged delayed OTPs, slow contact sync and sign-up lags, and said it is expanding server capacity to stabilize onboarding.
• Sridhar Vembu said Arattai runs entirely on Zoho’s own infrastructure using proprietary systems rather than AWS, Azure or Google Cloud.
• Calls on Arattai are protected with end-to-end encryption, while E2EE for text chats is not yet live and is expected in the coming weeks.
• The app matches core messaging features and adds tools such as meetings, mentions, channels, Android TV support and large group limits.
