The gap Bizzabo leaves open
Bizzabo's strength is the marketing layer — moving prospects from awareness to registration, then tracking the analytics. The communication layer between registration and attendance is primarily email-driven, which means it lives or dies on inbox open rates.
Email open rates in B2B events hover around 20%. Marketing teams running Bizzabo know this. They've typically built the registration funnel beautifully — and then watched attendance lag the registration numbers by 30%+.
KATHN addresses that gap directly. AI voice confirmation calls reach the 80% who never opened the email. SMS picks up the last-mile attendees. AI chat agents handle the inbound queries that email reminders generate. The marketing layer drives registration; KATHN drives the attendance those registrations were supposed to produce.

How KATHN works alongside Bizzabo

We recommend starting with a scoped pilot — a real campaign on a real event, not a sandbox. Bizzabo continues to power registration, marketing, and analytics. KATHN powers the voice, chat, and SMS layer that moves attendance numbers. Pricing is quoted before any work begins.
Frequently Asked Questions
Is KATHN a Bizzabo replacement?▾
No. Bizzabo is an enterprise event marketing platform — strong on registration, event marketing automation, CRM-native integrations, on-site event tech, and ROI analytics. KATHN is an AI communication layer running voice, chat, and SMS across the attendee lifecycle. The two solve different problems and integrate with each other. Most teams keep Bizzabo for event management and add KATHN for high-volume attendee communication that Bizzabo leaves to email.
What does Bizzabo not do that KATHN does?▾
Bizzabo relies on email and in-platform notifications for attendee communication. It does not run AI voice outreach to confirm attendance at scale, AI chat agents on your website or social channels, or AI-driven SMS sequences. Bizzabo's strength is the marketing and analytics layer — KATHN's strength is the communication layer that drives the attendance those analytics measure.
How does KATHN integrate with Bizzabo?▾
KATHN integrates with Bizzabo natively. KNVI Labs handles the integration setup as part of the standard 5-day engagement — attendee data flows from Bizzabo to KATHN, which then runs voice, chat, and SMS across pre-event, day-of, and post-event stages. There is no technical lift on the event team.
Bizzabo vs Cvent: which is right for me?▾
Cvent is broader — full registration, venue sourcing, marketing, on-site, and enterprise reporting. Bizzabo is leaner with a stronger event marketing and attendee experience focus, particularly for marketing-led events. Marketing teams running B2B brand events tend to find Bizzabo more aligned to their needs. Enterprise teams running flagship conferences with complex venue sourcing tend to need Cvent. Both leave the same attendee communication gap that KATHN fills.
What does Bizzabo do better than KATHN?▾
Bizzabo is stronger on event registration and ticketing, event marketing automation, CRM and marketing tech integrations, on-site check-in and badging, sponsor ROI reporting, and the event marketing playbook overall. For teams whose primary need is a marketing-aligned event management platform, Bizzabo is the right tool. KATHN does not compete with Bizzabo on those features.
