Scoring
Who gets scored
Anyone who talks to your buyers: account executives, SDRs, founders who sell, managers on the call, and the AI agents you put in front of customers. One standard for all of them, so feedback means the same thing for a new SDR and for an agent.
Claude
Why not just use Claude?
You can get Claude to score a call in an afternoon. We use it every day. What takes years is a standard a team trusts: written levels for every skill, reference calls rated by trained people, one standard for every rep and every agent, quotes checked against the transcript, and a person who settles disputes. Big Sister maintains that standard, and your Claude can read it through our connector.

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 everyone on your side of the call, people and AI agents. 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.
