The Challenge
Kalyxi's sales team was conducting numerous calls but lacked systematic feedback and coaching. The manual review process was:
- Inconsistent: Ad-hoc call reviews without structured criteria
- Time-Intensive: Sales managers spending hours reviewing recordings
- Delayed Feedback: Days between calls and actionable insights
- Knowledge Gaps: No systematic integration with sales training materials
- Scalability Issues: Unable to review all calls as team grew
Specific Challenges
- Subjective Reviews: Different managers provided inconsistent feedback
- Training Disconnect: Sales techniques not aligned with best practices
- Resource Discovery: No systematic way to find relevant training content
- Performance Tracking: Limited visibility into sales skill development
- Team Coordination: Feedback delivery was fragmented across tools
The Solution
I developed an AI-powered n8n workflow that automatically analyzes every sales call, provides structured coaching feedback, and delivers actionable insights with relevant training resources.
Intelligent Analysis Architecture
AI-Powered Call Review System
// Core sales analysis prompt from n8n workflow
const SALES_ANALYSIS_PROMPT = `
You are a world-class sales strategist reviewing a sales call transcript.
Evaluate like an elite sales coach — critical, prescriptive, and high-signal.
CRITICAL REQUIREMENTS:
1. Read the ENTIRE transcript thoroughly - every detail matters
2. Reference online sales training resources for best practices
3. Identify exact quotes and timestamps for all feedback
4. Look for payment information to confirm closed deals (NEVER DISPLAY ACTUAL ACCOUNT NUMBERS)
5. USE SLACK EMOJI CODES (like :point_right:) NOT ACTUAL EMOJIS
Structure your analysis as:
