Business messaging & voice infrastructure · Chennai · Since 2003
We were sending bulk SMS before smartphones reached India.
StarDotStar has built and operated WhatsApp, SMS, voice, chatbot and AI channels for Indian businesses since 2003 — part of StarDotStar Software Ltd, founded in Chennai in 1991.
One vendor for every channel, instead of six.
Most businesses stitch together a WhatsApp vendor, an SMS gateway, a voice broadcast tool, a chatbot builder and a data provider — five contracts, five support lines, five things to keep in sync. StarDotStar runs all of it as one stack, so a conversation that starts on WhatsApp can move to voice, get logged against the same customer record, and feed the same campaign data.

01
One support line, not five
Every channel is built and supported in-house from Chennai — no chasing a US vendor's ticket queue for an SMS delivery issue.
-
02
Channels talk to each other
A customer who starts on WhatsApp, gets an SMS reminder, then a voice call — all logged as one conversation, not three disconnected ones.

03
20+ years of India-specific delivery experience
TRAI compliance, DND handling, regional language support — built for how Indian businesses actually communicate, not adapted from a global template.
