TL;DR — Key Takeaways

- 2Kairos is best-in-class for the communication layer outside the app — pre-event voice confirmation, day-of AI chat, SMS reminders, post-event follow-up.
- 3Whova reaches users who download the app — typically 40–60% of registrants. Kairos reaches every registrant through voice, chat, and SMS.

The gap Whova leaves open
Whova's strength is the mobile app experience during the event itself. Its communication tools work primarily through the app — push notifications, in-app messaging, session reminders. That's great for users who downloaded the app.
Most events see 40–60% app download rates among registrants. That means roughly half of your registered attendees never see Whova's reminders. They're relying on the registration confirmation email and whatever Cvent or your registration platform sends them. That's the no-show gap.
Kairos reaches the other 40–60%. AI voice calls don't require an app download. SMS reaches everyone with a phone number. AI chat lives on your event website. The communication layer runs in parallel with Whova, hitting every registrant through the channel they actually use.

How Kairos works alongside Whova
Kairos integrates with Whova natively. Attendee data flows from Whova to Kairos as part of the standard 5-day setup. KNVI Labs builds, configures, and operates every voice and chat agent — there is no technical lift on your event team.
We recommend starting with a scoped pilot. A real campaign on a real event, not a sandbox. Voice agents call your registrants. Chat agents handle inbound queries on the event website. SMS reminders run in parallel with Whova's app notifications. The two systems complement each other. Pricing is quoted before any work begins.
Frequently Asked Questions
Is Kairos a Whova replacement?▾
No. Whova is an event app and attendee engagement platform — strong on networking, in-app Q&A, session scheduling, and the mobile experience. Kairos is an AI communication layer running voice, chat, and SMS across the attendee lifecycle. The two solve different problems and work alongside each other. Most teams keep Whova for the in-event app and add Kairos for the pre-event, day-of, and post-event communication that lives outside the app.
What does Whova not do that Kairos does?▾
Whova focuses on the in-event experience through its mobile app. It does not run AI voice outreach to confirm attendance before the event, AI chat agents on your website or social channels for inbound questions, or automated SMS reminder sequences. Whova's notifications work only for users who have downloaded the app — which is a fraction of registrants. Kairos reaches every attendee through their preferred channel.
How does Kairos integrate with Whova?▾
Kairos pulls attendee data from Whova as part of the standard 5-day setup. KNVI Labs handles all integration work — voice agents call registrants, chat agents handle inbound queries, and SMS sequences run alongside Whova's native app notifications. There is no technical lift on the event team.
Whova vs Cvent: which is right for me?▾
Cvent is the heavyweight all-in-one platform — registration, venue sourcing, marketing, full enterprise reporting. Whova is leaner and significantly cheaper, with a much stronger attendee app and in-event networking. Mid-market teams who don't need venue sourcing or complex enterprise reporting tend to find Whova easier to operate. Larger enterprises with multi-track flagship events tend to need Cvent's breadth. Both leave the same gap on attendee communication — which is where Kairos fits.
What does Whova do better than Kairos?▾
Whova is stronger on the in-event mobile app experience, attendee networking and matchmaking, session Q&A inside the app, agenda browsing, and community engagement features. For teams whose primary need is a great attendee app for the event itself, Whova is the right tool. Kairos focuses narrowly on the communication layer surrounding the event and does not compete with Whova on app features.
