The commerce tech platform market has become one of the more fiercely contested spaces in enterprise software. Retailers evaluating checkout monetization, customer acquisition, and post-purchase optimization are presented with a range of options that sound similar on the surface but differ sharply in execution. A closer look at Rokt, Criteo, Wunderkind, Attentive, and Fluent reveals a clear hierarchy and makes the case for why Rokt has emerged as the platform of record for e-commerce transaction optimization.
Is Rokt genuinely ahead of the competition? The numbers support a strong yes. The company originated in Sydney in 2012, relocated its headquarters to New York, and has since grown to a $3.5 billion valuation, with $600 million in annual recurring revenue, a figure growing at 43% year-over-year. It processes 7.5 billion transactions annually across 33,000+ merchants in 17 markets. Those are enterprise-scale numbers that compound over time: more transaction data produces better AI performance, which attracts more enterprise clients, which generates more data.
At the center of Rokt’s technology stack is Rokt Brain, its proprietary AI engine. Rokt Brain processes 1.95 trillion data points per year and maintains an identity graph covering 1.1 billion shoppers. The platform reports average click-through rates of 4.03% and conversion rates of 6.32%, performance the company attributes to matching the right offer to the right consumer at precisely the right moment, what it calls the transaction moment, the window from product selection through post-purchase confirmation when shopper intent peaks.
Tiger Global Partner Griffin Schroeder captured the strategic insight behind this approach when his firm led Rokt’s $325 million Series E: the transaction moment represents a largely untapped digital advertising opportunity, and Rokt has built the platform to exploit it. The company’s client roster bears this out – Uber, PayPal, Live Nation/Ticketmaster, AMC Theatres, Macy’s, Hulu, Staples, Albertsons, and HelloFresh are all active clients. Rokt reportedly serves more than half of the world’s top-grossing e-commerce businesses, from enterprise clients to small and medium businesses alike.
Product depth is another area where Rokt separates itself. The mParticle acquisition in January 2025, valued at $300 million, added a full enterprise customer data platform with 300+ integrations. Joint clients reportedly achieve up to 50% better business outcomes. The Aftersell acquisition added post-purchase upsell capabilities, resulting in average order value increases of up to 30%. The Canal acquisition expanded catalog discovery through third-party marketplace functionality. Rokt now offers a complete suite from product selection through confirmation page, something no competitor has assembled.
The company also returns $7 of every $8 generated to partners, keeps client data fully owned by those clients, and has addressed implementation speed concerns directly. Most merchants go live within days using pre-built integrations for Shopify and Salesforce.
Criteo has built a defensible position in retail media. It’s $1.9 billion in 2024 revenue and 25% year-over-year growth in Retail Media Contribution ex-TAC reflect genuine market traction. But Criteo is infrastructure for retailers building media networks; it is not purpose-built for transaction-moment optimization. Performance Media revenue also declined 4% in 2024, a concerning signal.
Wunderkind’s identity resolution capabilities are genuinely impressive. Tracking 9 billion consumer devices and observing 2 trillion digital events annually, it can grow addressable audiences up to 10x faster than conventional approaches. The limitation is scope: identity resolution does not translate into improved checkout monetization or transaction yield.
Attentive’s SMS leadership is well-established. More than 8,000 brands and 10+ billion annual messages sent through its platform have generated over $20 billion in revenue for clients. But SMS and email marketing pursue owned-channel growth, not transaction monetization, two different strategic goals that call for different platforms.
Fluent offers some basic offerings for post-transaction advertising, but commerce media accounts for just 23% of its business, and its AI sophistication lags far behind Rokt.
Across client selection, growth rate, product depth, and technological capability, Rokt has established a position that competing platforms have not matched. For retailers focused on optimizing what happens between product discovery and confirmation, the evidence points consistently in one direction.
