Segment Ninja is revenue intelligence for ecommerce brands on Klaviyo, their agencies and the tools they run on. Most of a brand’s revenue comes from a small group of best customers. Klaviyo and today’s AI tools can sort those customers by what they’ve bought. They still can’t tell you who those customers are, why they’re worth more, or where to find more of them. That’s the gap we fill. We read a brand’s real order history in Klaviyo, identify the buyers who drive the most revenue, and describe them in terms retention and media teams can act on. Those best-customer audiences can then be reached on 150+ paid platforms, including Google, Meta, streaming TV and podcasts. Brands spend on the people most like the customers they already have, not on broad lookalikes. Our models were built and tested on more than 1M Klaviyo profiles and 3M+ transactions. Paying DTC brands from $1M to over $100M in annual revenue, and the agencies behind them, already run Segment Ninja inside their Klaviyo accounts. Across our current clients, brands reach less than 0.3% of the consumers who match their best customers, so the room to grow is large. Alen, the air purifier brand, used its Segment Ninja best-customer audiences for acquisition and saw 5.2x ROI on segmented acquisition email and 17x ROI verified with an address-level matchback. Who we work with: • Ecommerce brands that want retention and acquisition built on their most valuable buyers • DTC media agencies and planners that want better audiences for their clients • Klaviyo ecosystem partners that want a revenue data layer to make their own products smarter Segment Ninja is an official Klaviyo Partner and works with any store platform connected to Klaviyo, including Shopify and WooCommerce.
