Using AI to Find Win Patterns Across 6 Months of Proposals

The scenario: A sales team submitted 149 proposals over six months with win rates fluctuating between 45–65%. They want to understand why some proposals win and others lose.

What they do: The team feeds six months of proposal performance data into Claude configured as a proposal analyst. Claude identifies five core proposal elements most correlated with wins and surfaces an unexpected correlation with implementation timeline clarity.

The result: The team adjusted proposal approach based on AI findings. Win rate increased 15% in one quarter.

A practical AI workflow for B2B sales — the prompts below run this play end to end, in Claude, ChatGPT, Gemini, or Copilot.
