Demo Performance Monitor
This drill creates an always-on monitoring system for the discovery-based demo pipeline. It tracks the full funnel from discovery call through demo to deal outcome, detects when conversion rates degrade, and surfaces which demo structures and pain-to-feature mappings produce the best outcomes.
Input
- PostHog events flowing from the
demo-prep-automationdrill (demo_prep_generated,demo_completed) - Attio deal records with BANT scores and demo outcomes
- Fireflies transcripts for demo calls
- At least 2 weeks of baseline demo data (minimum 10 demos)
Steps
1. Define the demo conversion funnel
Using posthog-custom-events, ensure these events are captured:
| Event | Trigger | Key Properties |
|-------|---------|----------------|
| discovery_call_completed | Discovery call transcript processed | deal_id, bant_composite, pains_identified |
| demo_prep_generated | Demo prep doc created | deal_id, pains_mapped, features_shown |
| demo_scheduled | Cal.com booking confirmed | deal_id, days_since_discovery, attendee_count |
| demo_completed | Demo call ended and logged | deal_id, outcome, pains_addressed, questions_asked, duration_minutes |
| recap_video_sent | Loom recap shared | deal_id, video_length_seconds |
| recap_video_viewed | Prospect watched recap | deal_id, watch_percentage, cta_clicked |
| next_step_committed | Prospect agreed to next meeting | deal_id, next_step_type |
| proposal_requested | Prospect requested pricing/proposal | deal_id, deal_value |
| deal_closed_won | Deal closed | deal_id, deal_value, days_in_pipeline |
2. Build the funnel in PostHog
Using posthog-funnels, create a saved funnel:
discovery_call_completed -> demo_scheduled -> demo_completed -> next_step_committed -> proposal_requested -> deal_closed_won
Break down by:
bant_compositebuckets (0-40, 40-70, 70-100) -- which BANT scores predict demo successpains_addressedcount -- does covering more pains increase conversionoutcome-- which demo outcomes lead to closed dealsdays_since_discovery-- does demo timing affect conversion
Save as: "Discovery-Based Demo — Full Funnel"
3. Build the demo effectiveness dashboard
Using posthog-dashboards, create a dashboard with these panels:
- Funnel conversion rates: discovery -> demo -> next step -> proposal -> closed won
- Demo-to-nextstep trend: weekly line chart of conversion rate
- Pain coverage vs outcome: scatter plot of pains_addressed vs next_step_committed rate
- BANT score vs demo success: bar chart showing conversion by BANT bucket
- Recap video engagement: average watch percentage and correlation with next step
- Time-to-demo: histogram of days between discovery and demo, overlaid with conversion rate
- Demo duration vs outcome: are longer demos better or worse
- Weekly demo volume: count of demos completed per week
4. Build n8n monitoring workflows
Using n8n-scheduling, create a daily cron workflow:
- Query PostHog for the last 7 days of funnel data
- Compute key conversion rates:
- Discovery-to-demo rate
- Demo-to-nextstep rate
- Demo-to-proposal rate
- Overall discovery-to-closed-won rate
- Compare to baseline using
posthog-anomaly-detectionlogic:- Normal: within +/- 15% of 4-week rolling average
- Warning: 15-30% below average for 3+ consecutive days
- Critical: >30% below average for 2+ consecutive days
- For Warning/Critical: send Slack alert with degradation details and probable cause
Using n8n-triggers, create event-triggered workflows:
- On
demo_completedwhere outcome = "no_interest": flag for demo quality review - On
recap_video_viewedwhere watch_percentage > 80% and nonext_step_committedwithin 48 hours: trigger follow-up reminder
5. Build the pain-to-feature effectiveness report
Create a weekly n8n workflow that:
- Pulls all
demo_completedevents from the last 30 days - Groups by features shown and pains addressed
- Calculates conversion rate for each pain-to-feature combination
- Identifies:
- Top 3 pain-feature combos that predict closed deals (prioritize showing these)
- Bottom 3 pain-feature combos that never convert (stop leading with these)
- Features shown but never connected to a pain (remove from demos)
- Generates a ranking report and stores it in Attio as a campaign note
6. Track demo quality signals from transcripts
After each demo, use Fireflies transcript + Claude to extract quality signals:
- Did the rep connect features back to specific pains mentioned in discovery ("You said X, this solves X")
- How many questions did the prospect ask (engagement signal)
- Did the prospect verbally commit to a next step
- Were there objections, and how were they handled
Score each demo 1-5 on: pain coverage, feature relevance, engagement, and close attempt. Correlate demo quality scores with deal outcomes over time.
Output
- Real-time demo conversion funnel with breakdown by BANT score, pain coverage, and timing
- Daily automated monitoring with anomaly alerts
- Weekly pain-to-feature effectiveness ranking
- Demo quality scoring from transcript analysis
- Historical trend tracking for demo-to-deal conversion
Triggers
- Daily monitoring: runs every day at 9 AM via n8n cron
- Weekly effectiveness report: runs every Monday at 8 AM via n8n cron
- Event-triggered: fires on every
