Rokt built from checkout problem
Rokt: the $480M/year ad network behind Uber & Lyft
This move shows that Rokt was built from a very specific checkout problem, not from a generic ad tech idea. Bruce Buchanan had seen in airline booking that the money was often in the add ons, not the seat itself. Buying Rocklive gave him a working affiliate engine and advertiser relationships, then rebranding it as Rokt turned that base into software and a network that could sit directly inside checkout flows across travel, tickets, food delivery, and ecommerce.

The core insight came from travel. After someone books a flight, they are unusually likely to also buy parking, hotels, insurance, or car rental. Rokt took that same moment of high purchase intent and applied it to Ticketmaster, Uber, Lyft, and other checkout pages where adjacent offers can be inserted without making the user leave the transaction.
-
Rocklive mattered because it gave Rokt a starting marketplace. Affiliate agencies already know how to source offers, track conversions, and get paid when a sale happens. Rokt then productized that into an SDK that merchants install, and into a two sided network where brands buy placement and publishers share the spend with Rokt.

That origin still shapes the business today. Rokt is not trying to win broad display advertising like Taboola or bank portal ads like Cardlytics. It is concentrated on the last screen before purchase, where intent is strongest, which helped it scale from $480M of revenue in 2023 to an estimated $600M ARR in 2024 and then expand into first party data tools with mParticle.
The next step is turning a checkout ad network into a wider commerce monetization stack. With AfterSell and mParticle, Rokt can move from showing one well timed offer at checkout to deciding what offer, message, or upsell a shopper sees from first visit through post purchase, which pulls it deeper into enterprise ecommerce budgets.
