Improve Event ROI with Smart AI Post-Call Analysis
5 min read
Introduction: The Event ROI Challenge
Events and webinars are powerful growth channels for B2B and B2C businesses alike. From product demos to thought-leadership sessions, companies invest thousands in ads, content, and speaker prep. Yet, here’s the problem:
40% of registrants never attend webinars (ON24).
Post-event surveys get less than 10% response rates.
Sales teams spend hours manually following up with attendees, often missing hot leads.
This is where AI-powered Post-Call Analysis (PCA) comes in. By combining AI voice agents with intelligent post-event insights, businesses can finally close the gap between event investment and measurable ROI.

Section 1: Why Traditional Event Follow-Ups Don’t Work
Emails get lost in crowded inboxes.
Manual sales calls take too long and lack consistency.
Event feedback collected via forms is usually shallow.
Most businesses end up knowing:
How many attended
How long they stayed
But they miss:
What attendees actually cared about
Which leads are sales-ready
Why some didn’t show up at all

Section 2: How AI Voice & PCA Solve This
Imagine this workflow:
Pre-Event Reminders (Boost Attendance)
AI voice calls remind attendees a day before:
“Hi Sarah, looking forward to seeing you tomorrow at 3 PM for our webinar on AI automation. Would you like me to send the link again?”Result: Attendance rates rise by 15–20%.
Post-Event Feedback (Capture Insights)
AI follows up with attendees and no-shows, asking:
“Did you find today’s session valuable?”
“Would you like the recording?”
“Are you interested in learning about [feature/product]?”
Every response is transcribed → fed into Post-Call Analysis.
PCA in Action (The Backend Magic)
Businesses can set custom questions inside PCA (e.g., “Was the attendee interested in a demo?”).
AI scans transcripts + context → generates direct answers.
Example: Instead of your sales team reading 100 call transcripts, PCA tells you:
“65% of attendees asked about pricing. 20% wanted a demo. 15% mentioned integrations.”

Section 3: Real-World Example
Let’s take a B2B SaaS company hosting monthly webinars:
Before AI Caller:
1,200 signups → 550 show up → <50 survey responses.
Sales team spent weeks filtering attendees to find interested prospects.
With AI Caller:
AI reminders → attendance jumped from 48% to 67%.
AI follow-up calls → captured 4x more feedback than emails.
PCA summarized insights → sales knew within 24 hours:
“120 people interested in integrations, 85 asked about pricing, 40 want demos.”Result → 30% more demos booked in the first week post-event.

Section 4: Why This Matters for ROI
Every webinar is an investment — ads, time, team, speakers. Without smart follow-up, most of that value is wasted. AI ensures:
✅ Higher Attendance – via proactive reminders.
✅ More Engagement – by making feedback conversational.
✅ Actionable Insights – through PCA-generated summaries.
✅ Better ROI – sales teams focus only on high-intent leads.
Events stop being a “branding activity” and become a lead engine powered by AI.
