The Problem

Your team wins
8%. Why?

Eight percent is the team average, the number most managers run on. Look closer and one rep closes at 17% while another sits at 2%. Everyone can see the gap. Almost nobody can explain it. The Sales Score does, because every call is graded against one standard.

ARAlex R.28817%74
JTJess T.30114%71
MKMichael K.2769%63
DPDana P.2596%58

Same 8% average. A 17% rep and a 2% rep. The Score is the only column that tells you which is which, and why.

3%
Reviewed by a human
A manager reviews under three percent of customer conversations in a typical week. The other ninety-seven percent go out unscored and unseen.
0
Shared standard
Every reviewer grades on a different gut. There is no single 0-100 standard, so two reps with the same problem get two different verdicts.
6mo
To catch a quiet miss
A rep can underperform for two quarters before the pipeline makes it obvious. By then the territory is cold and the quarter is gone.

How many customer
conversations are you
flying blind on?

Phone, Zoom, Teams, Meet - every conversation between a rep and a customer.

Question 1 of 3
How many reps talk to customers?
Anyone running live conversations - phone, Zoom, Teams or Meet.
How many of those conversations does a manager actually review each week?
Watched or listened to end to end, not skimmed.
Do reps score every conversation against one defined standard?
Same rubric, every conversation, every rep.
Your team runs about 0 customer conversations a month.
0
conversations a month with no objective signal

That gap is where Rep #8 hides at 2% for six months. Big Sister scores every conversation automatically, against one defined standard - a default skill set that works out of the box, plus custom sets tuned to your deal motion.

How It Works

Score every
conversation.

One objective 0-100 Sales Score per rep, the moment a call ends - against one defined standard, every rep, every week, no sampling. See how the score is built →

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. The stretch after the SDR hands off is where deals quietly break and no one has objective signal. Big Sister scores all of it.

The Market Today

Your stack records
the game. Nobody
scores it.

There is a layer missing above the tools you already run. The record exists. The tape exists. The objective score does not. That is the layer we built.

Layer 1
CRM
Records
Logs what happened: the deal, the stage, the close date. The system of record. It does not judge the conversation.
Layer 2
Notetakers
Keep the tape
Capture and transcribe the call so you can go back and listen. The system of replay. They hand you hours, not a verdict.
The missing layer
Big Sister
Scores every game
The referee that sits above the stack and grades every call 0-100 against one standard. Use it with the tools you already have.

CRM = record. Notetakers = tape. Big Sister = referee that scores every game. Big Sister reads your phone calls, your CRM and your notetaker transcripts today. Emails and messengers next.

Why Big Sister

Built by people
who ran sales
teams.

Not who observed them from a dashboard. We scored teams by hand for years, watched gut-feel management promote the wrong reps, and built the referee we wished we had.

From the Floor

What the score
actually changes.

"If you have ever been subjected to Salesforce and tried to use external tools to dig into why your conversion rates weren't acceptable, you need Big Sister AI. This is real AI at work, not a sprinkling of pixie dust over a dataset. I wish I'd had Big Sister when my startup had salespeople spread across the world. Try it. You will not be sorry."

"Sales and communication is one of the most crucial aspects of the business. The Big Sister team understands it deeply. They get the core needs on both sides, which is a game changer. System, strategy, different angles of view, AI - these are the tools the Big Sister team uses."
