Big Sister AI V2 · Live

One sales method for your people and your agents.

Big Sister scores each rep's real calls on 18 skills and shows the moment behind every score. Agents work the same method: an inbound agent answers visitors on this site, and a replay coach takes a rep back through a weak moment by voice.

Where We Work

From deal created to close. The stretch nobody scores.

Every call, meeting, and message inside the deal - from created to won or lost - scored for every rep and AI agent. From the first real conversation with a buyer to the closed deal is where revenue is decided, and where no one has objective signal. Big Sister scores all of it.

The stretch nobody scores

Big Sister scores it call by call. An inbound agent works before the first call, and a replay coach works after a scored one.
