Klaviyo B2C clients can identify the most valuable customers and target them with demographic, lifestyle, and psychographic data thanks to an integration of the Claritas tool, Prizm Premier, within Segment Ninja’s Klaviyo platform. 

Who’s who in this arrangement?

Segment Ninja is an approved tech partner of Klaviyo, or an integrated software vendor.  

"Our mission was simple: to help Klaviyo users know exactly who their best customers are and how to engage, convert and acquire more like them," said Jim Kalogerakos, founder and CEO of Segment Ninja. “By partnering with Claritas, we’re enabling brands and their agencies to turn first-party data into precision-targeted campaigns.” 

As an incentive, Segment Nina is offering a free trial to the first 100 brands and agencies.

The other participant, Claritas, is a consumer segmentation firm. 

According to Segment Ninja, the new arrangement allows Klaviyo users to:

• Analyze and enrich customer lists with Prism Premier data in real time. 
• Generate detailed personas to drive more personalized cmpaigns. 
• Access geospatial mapping.
• Acquire best customers via email and through over 150 channel and platform partners. 

Alen, a seller of air purification products, was the first firm to adopt the new solution. 

Segment Ninja claims that brands like Alen were able to identify the top 20% of customers who drive 80% of revenue and leverage that knowledge across welcome series, abandoned cart, post-purchase, and win-back flows.

"Our mission at Claritas has always been to help brands know more and do more," says Jeff Stevens, SVP of Strategic Partners at Claritas. “Segment Ninja delivers PRIZM Premier insights directly into the tools brands already use, making precision marketing easier than ever.”
