Ep 223: The new era of rewarded traffic

Lenny Rabin, founder of Brown Boots and Go-Kart, joins Taylor Lobdell to dissect the evolution of rewarded user acquisition, focusing on how direct publisher-advertiser relationships can solve long-standing industry inefficiencies. Rabin, with over a decade in rewarded traffic and ad tech, explains why most publishers dislike third-party monetization platforms, how custom tech stacks like Go-Kart enable deeper, more transparent deals, and what both advertisers and publishers must do to thrive in an increasingly mainstream and competitive rewards ecosystem. This episode tracks the practical realities of running direct-sold inventory at scale, dives into shifts in audience intent (from GPT sites to fintechs), and breaks down why most campaigns fail. Rabin also shares founder lessons for building in ad tech without an engineering background.
