Wunderkind Joins Klaviyo App Marketplace to Power Smarter, Identity-Driven Marketing

I’m excited to share some big news: Wunderkind has officially joined Klaviyo’s K:Partners Technology Program, and our app is now live in the Klaviyo App Marketplace. This marks a pivotal next step in our partnership strategy — and a meaningful shift in how we show up for the brands and agencies we serve.

Klaviyo is the only CRM purpose-built for B2C, bringing marketing, service, analytics, and data together in one easy-to-use platform. With real-time insights, automation, and AI-powered recommendations, brands can deliver personalized experiences and drive smarter, faster growth without extra complexity. When you connect Wunderkind with Klaviyo, you’re able to turn richer identity and intent data into better-performing campaigns, directly inside your Klaviyo account.

For years, Klaviyo has been a go-to platform for lifecycle marketing, giving brands an intuitive way to build, send, and measure email and SMS campaigns. At Wunderkind, we’ve been focused on solving a complementary (and increasingly urgent) problem: helping brands recognize more of their website traffic, understand real-time intent, and trigger one-to-one messages that actually convert.

Now, as a Klaviyo Preferred Tech Partner, we’ve brought those strengths together.

What this partnership unlocks for brands

With Wunderkind published on the Klaviyo App Marketplace, brands can pair Klaviyo’s native email and SMS execution with Wunderkind’s identity resolution and AI-powered decisioning, without disrupting their existing workflows.

Wunderkind fuses identity and AI to turn anonymous traffic into known customers, without relying on third-party cookies. Our Identity Graph powers privacy-compliant recognition across 1B+ profiles and 9B+ devices, giving brands a much clearer picture of who is on their site and what they care about in real time. Within Klaviyo, that unlocks:

• Smarter identity resolution
  Wunderkind recognizes users across devices and sessions using first-party data, then passes those insights into Klaviyo so brands can message real people — not cookies or guesswork — directly from within Klaviyo.
  
  
• Real-time Signals and triggers
  Our Signals for Klaviyo experience uses identity and behavioral data (browse, cart, price sensitivity, lifecycle context, and more) to trigger highly personalized emails and texts, with every send executed natively in Klaviyo. The result is expanded reach, more relevant messaging, and increased revenue from the traffic you already have.
  
  
• Enriched omnichannel experiences
  Because Wunderkind is built as a decisioning layer, brands and agencies can orchestrate when, where, and how to engage, using Klaviyo as the send engine and source of truth for reporting. That means fewer generic blasts, more behavior-driven journeys, and better performance across your owned channels.
  
  

Working in partnership

This listing is more than a logo moment; it represents a real evolution in our relationship with Klaviyo — from perceived competitor to strategic partner.

By meeting brands where they already are, we’re making it easier to:

• Add Wunderkind as an identity and AI “upgrade” to existing Klaviyo programs
• Create net-new opportunities for both sales teams and agency partners
• Drive incremental pipeline and revenue growth for Wunderkind, Klaviyo, and the brands we jointly serve

In short: if a brand has already invested in Klaviyo, this partnership helps them get more out of it, without adding complexity or ripping anything out.

Looking ahead

Being published on the Klaviyo App Marketplace is a significant milestone for Wunderkind, and just the beginning of what we plan to build together.

In the coming weeks, we’ll be rolling out more enablement, stories, and playbooks to help brands and agencies tap into this partnership. For now, I’m thrilled we can finally say:

Wunderkind and Klaviyo are officially in market together — turning anonymous traffic into known customers, and known customers into long-term revenue growth. To see what the integration makes possible and install it in just a few clicks, explore our Klaviyo listing here.
