Tools & the bottom line
Google Ads (Search & PMax)Meta Ads ManagerLinkedIn Campaign ManagerWhatsApp Business API (Wati)Brevo Email AutomationLeadSquared CRMGoogle Analytics 4Canva Pro
Solo-managed a ₹30.4 Lakhs budget over 35 days to deliver 142 stall bookings (100% floor sellout), 12,450 verified attendee registrations, and ₹2.8 Cr+ in direct booth fees and sponsorship pipeline value (9.2x ROAS).
What I'd take from this
- For large-scale expo marketing, integrating instant two-way WhatsApp communication delivers 10x faster stall booking velocity compared to traditional phone or email follow-ups.
- Pairing industry title sponsor authority (Adani Solar) with clear commercial buyer attendance numbers is the single most decisive factor in closing high-ticket B2B expo exhibitors.
