How It Works

Four layers.
One score you can audit.

Big Sister AI is a Revenue Governance Layer. This is the path every sales interaction takes: from raw conversation to a 0-100 Sales Score a manager can defend, with the evidence attached.

System Architecture
Layer 01Sources
CRM Notetaker Dialer Offline meetings

Calls, emails, in-person meetings and CRM activity flow in automatically. No manual logging.

Layer 02Scoring
18 skills 5-point scale Composite 0-100

Multi-provider judging on Microsoft Foundry. The right judge for each skill.

Layer 03Governance
Timestamp citations Appeals to a second judge Over 10% resampled

Every score cites the moment in the transcript that earned it.

Layer 04Delivery
Sales Scores Skill breakdowns Team views

Back into the workflow, where decisions are made.

01

Sources

Big Sister connects to the systems your team already uses. Calls, emails and CRM activity flow in on their own; nobody logs anything by hand.

Technical

Read-only connectors to your CRM, notetaker and dialer. Offline meetings — recorded in-person conversations — are ingested the same way as calls. No change to rep workflow, no new data-entry surface, no agent installed on anyone's machine.

02

Scoring

Every interaction is scored against one defined standard: 18 sales skills, each on a 5-point scale, rolled into a single 0-100 Sales Score.

Technical

Scoring runs on Microsoft Foundry across multiple model providers. Each skill is matched to the judge that scores it most reliably. Judges change as the field moves; the rubric they score against does not.

03

Governance

A score you can't check is an opinion. Every score shows the exact moment in the conversation that earned it, so anyone can verify it.

Technical

Each skill score cites its transcript timestamp. Disputed scores are appealed to a second, independent judge. Over 10% of interactions are resampled for review as a standing quality check.

04

Delivery

Results land where decisions are made: rep scores, skill breakdowns and team views, inside the workflow your managers already run.

Technical

Scores and skill-level detail flow back into dashboards, team views and the tools your team lives in. The evidence behind any number is one click away.

Trust

Built to be trusted
with your pipeline.

Your data stays yours

Customer data is not used to train models. Your conversations score your team and nothing else.

Claude orchestrates

Claude coordinates the system end to end, from intake to delivery, so every interaction follows the same governed path.

No single-vendor dependency

Scoring is model-agnostic by design: no single provider is a dependency of the scoring layer. Judges can change; your standard, your scores and your history do not.
