Webinar Growth Engine
Built the analytics, automation, and AI calling layer that more than doubled webinar attendance using data-driven interventions.
Peak show-up rate (from 36% baseline)

The Problem
We run weekly paid masterclass webinars. Despite spending on ads and getting 3,000-5,000 registrations per week, only about 36% of registrants actually showed up. That's 3,200+ people registering and never appearing. Every no-show is wasted ad spend.
We needed to understand WHY people weren't showing up, build systems to recover them, and measure what actually worked.
What We Built
An end-to-end webinar intelligence system:
- Zoom API integration pulling real-time attendance data
- n8n workflow automation for event-driven actions
- GoHighLevel CRM for contact management and communication triggers
- Custom analytics dashboard tracking registration-to-attendance-to-peak-viewer funnel
- AI calling bots (built on Wavelength) for no-show recovery and pre-webinar warm-up
The key insight was treating the webinar like a product funnel with measurable conversion at every stage — not just "send reminders and hope."
The Numbers
| Metric | Value | Context |
|---|---|---|
| Baseline show-up rate | 36.2% | Consistent across 7 weeks of data (33-40% band) |
| Best show-up rate | 81.3% | 2,197 attendees from 2,701 registrations |
| Improvement | 2.25x | More than doubled attendance |
| Weekly registrations range | 2,701 to 5,212 | Tracked across 8 consecutive weeks |
| Peak viewer retention | 56-72% | Of those who showed up, this many stayed to peak content |
| Drop-off before peak | 27-43% | 400-750 people lost between join and peak each week |
| Best retention week | 72.3% | Feb 28 — identified as anomaly, analyzed for replication |
| Total registrations analyzed | 34,070 | Across 8 weeks of data |
Key Engineering Challenges
1. Identifying the Real Bottleneck
Registration volume did NOT correlate with show-up rate. The two highest registration weeks (5,056 and 5,212) had 33% and 39.6% show-up. Meanwhile the smallest registration week (2,701) had 81.3%. More leads ≠ more engaged leads. Quality of the reminder/warm-up touchpoint matters more than top-of-funnel volume.
2. Peak Viewer vs Show-Up Distinction
"Showed up" and "was there for the pitch" are completely different metrics. A consistent 35-40% of attendees dropped off before peak content. The real conversion funnel had TWO leaks: registration-to-attendance AND attendance-to-peak. Most webinar operators only measure the first one.
3. Retargeting Strategy
The 81.3% week used a Zoom link retargeting approach (sending the direct Zoom join link to registered contacts) instead of the standard landing page reminder. This single change was responsible for the entire 2.25x improvement. Discovered through systematic A/B comparison across weeks.
