Manifesto

Big Sister AI
One sales method for humans and AI agents
v2.2 / September 2026

Sales is a human craft. What every sales leader wants is reps who can see their own gaps and fix them without being told. Big Sister scores every customer conversation against one written standard, for reps and AI agents alike, with the evidence attached. The rep sees it first, so the coaching conversation starts at what to fix.

Your CRM has the outcome and your recorder has the call. We score the call against a written standard and handle disputes about the score.

01

We start at the first real conversation.

Our work starts at the first real conversation with a real buyer and ends when the deal is won or lost. That is where revenue is decided, and it is the only part we work on.

02

We build AI around the humans, not instead of them.

Our agents take CRM entry and call prep off a salesperson’s plate. You decide what else to hand over. You keep the relationship. We keep the quality.

03

Where the method comes from

Since 2009 we have worked inside sales teams as consultants. What we learned is written down as the Big Sister Method, tuned to your product and your buyers. It learns from your results, not ours.

04

Reps and agents are held to the same standard.

One written Sales Score Standard, built for coaching and training, and applied to the agents we build ourselves. Before an agent talks to your customers, it passes the standard your reps are held to.

05

You get a score, and the moment in the call that earned it.

The rep sees it first and can dispute any score to a trained human referee. A low score becomes a Second Chance. A score you cannot check is an opinion with a decimal point.

THE ASK

Send us your recorded customer conversations.

From Fireflies, Zoom, Meet or your CRM. Within days, each rep sees where they are strong and what to work on, with the moment in the call behind every score.

Five principles for measuring human reps and AI agents the same way.
