Klaviyo Marketplace Adds Wunderkind to Boost Identity-Driven Revenue for Brands
TECHNOLOGY
Wunderkind, the AI decisioning platform that delivers identity resolution and cross-channel personalization to scale performance and reach has announced its official debut on the Klaviyo App Marketplace.
For e-commerce brands, the "Identification Gap" is a silent revenue killer. In an era where roughly 98% of website traffic remains anonymous and third-party cookies are a relic of the past, most marketers are effectively flying blind. Today, Wunderkind and Klaviyo (NYSE: KVYO) announced a strategic integration designed to turn those anonymous visitors into known customers.
By joining the Klaviyo App Marketplace, Wunderkind is bringing its AI-powered identity resolution directly into the B2C CRM used by nearly 200,000 brands.
Layering Identity into the CRM
The core of this partnership is the seamless layering of Wunderkind’s Identity Network, built on over 9 billion device profiles and over a billion unique user identities, into Klaviyo’s unified customer profiles. This allows marketers to recognize shoppers earlier in their journey, across different sessions and devices, without adding complexity to their tech stack.
“Together, Klaviyo and Wunderkind deliver a future-proof, high-performance solution,” said Richard Jones, Chief Revenue Officer at Wunderkind. “This integration enables brands to activate identity-powered insights directly within Klaviyo... driving smarter decisions and measurable revenue growth.”
Triggered Revenue: The 8X Multiple
The results of identity resolution are not just incremental; they are transformative. Brands leveraging Wunderkind’s identity framework have seen up to an 8X increase in triggered revenue. By recognizing more visitors, brands can trigger hyper-personalized email and SMS flows, like cart abandonment or price drop alerts, at a significantly higher match rate than traditional platforms.
“This integration gives brands access to identity insights directly within Klaviyo's real-time customer profiles,” added Anne Prins, Vice President of Global Product Partnerships at Klaviyo. “It helps them recognize more customers and build stronger relationships, all from a single system of record.”
Operational Efficiency in a Cookieless World
As privacy regulations tighten and the "walled gardens" of advertising grow taller, the ability to own your first-party identity data is the ultimate competitive advantage. The Wunderkind-Klaviyo integration allows brands to:
Identify more visitors across devices and sessions using a proprietary identity graph.
Scale triggered messaging with higher match rates for email and SMS.
Boost Lifetime Value (LTV) through consistent, personalized experiences that feel 1:1 rather than 1:Many.
The "Identity Moat"
In 2026, the most successful e-commerce brands are building an "Identity Moat." The partnership between Wunderkind and Klaviyo is a masterclass in Frictionless Integration.
For the Retail Economy, the lesson is clear: if you don’t know who is on your site, you can’t market to them. By moving identity resolution into the CRM, these two giants are proving that Identification is the new Acquisition. In the Relationship Economy, the winner is the brand that stops guessing and starts recognizing.
