About TripleLift

TripleLift is the Creative SSP, evolved for the orchestration era and powered by TL Spark, our intelligence layer. We help brands move beyond buying impressions to engineering impact by bringing creative, curation, audience, and measurement together as one coordinated system. Through more than 1 trillion monthly ad transactions, we help publishers and platforms maximize the value of their inventory while elevating the advertising experience.

Built on a foundation of creative innovation, TripleLift has evolved from native advertising into comprehensive omnichannel solutions spanning display, online video, and connected TV. By combining premium creative formats, actionable intelligence, and first-party publisher data, we help brands drive meaningful outcomes while enabling publishers to unlock the full potential of their inventory.

Our philosophy is simple: impact by design. We believe creative should earn attention, intelligence should guide decisions, and orchestration should drive outcomes.
