Arattai：Zoho 的低调通讯押注，因印度想要本土 WhatsApp 而爆红

做的是什么生意

Arattai (casual chat in Tamil) is Zoho's messaging and calling app: chat, voice and video calls, group chats, business tools, built for low-end phones and slow connections

启动资金：Built inside bootstrapped Zoho on its own messaging framework — no external funding disclosed

起因

Arattai soft-launched in 2021, built quietly by a Zoho team that worked for over five years without expecting the product to take off, per founder Sridhar Vembu. Zoho's advantage was patience and existing infrastructure: a messaging/AV framework perfected over 15 years, run across its own servers and data centers.

经过

For most of 2025 the app stayed below 10,000 downloads. In late September a national push for self-reliance and indigenous digital alternatives suddenly made a domestic WhatsApp rival relevant. Daily signups jumped from 3,000 to 350,000 within three days, active users rose 100x, and Arattai became the most-downloaded app in India — 7.5 million downloads by October 3, 2025.

结果

Live and scaling, but retention is unproven: Zoho rushed plans forward and is working on end-to-end encryption for messages, while WhatsApp keeps roughly 500M monthly users in India

可借鉴之处

当浪潮来临时，耐心的产品押注会有回报：Zoho 多年来基于自有基础设施构建 Arattai，因此能在几天内吸收数百万下载量。
