Call corpus Fathom + HubSpot Group by deal Won / lost tagged Pattern analysis Wins vs losses Findings Patterns + coaching

The agent assembles each deal's calls, tags them won or lost, finds the patterns that separate the two, and reports them with example moments and coaching notes.

The Problem

The team knew which deals they won and lost, but the why was buried inside hundreds of call recordings. Understanding what actually separates a win from a loss meant manually reviewing calls, which nobody had time for. As a result, win/loss reasoning stayed anecdotal, inconsistent, and unbacked by data.

What We Built

A batch-analysis agent that assembles each deal's full call history, tags it won or lost based on its CRM stage, and analyzes the entire corpus to surface the patterns that recur in wins versus losses. Each finding comes with its win-rate and loss-rate (with raw deal counts), a confidence level, paraphrased example moments from real calls, and a concrete coaching recommendation. It runs on a schedule over the growing body of calls, and reports patterns at the team level rather than scoring individual reps.
