AI SDR for Buying-Intent Prospects (LinkedIn + WhatsApp)

Sbl.so is an AI SDR platform for B2B teams to discover prospects showing real buying intent, reach them across LinkedIn and WhatsApp, and automaticall…

In plain English

Companies that look ready to buy are what Sbl finds for business teams, then it reaches people on LinkedIn and WhatsApp. The AI carries the conversation, the follow-ups, the check on who is a real fit, and the booking of a meeting, while a human still reviews the messages. Teams pay each month by how many messages they send or how many seats they use, because that work can fill a person's day. The AI does a large share of the writing and the billing. Shubham Kumar still does a fair amount, checking quality, helping teams, and stepping in when a conversation needs care.
