About this episode

Lotem Karmon discusses the ad tech crisis stemming from a subsidy ending and the unnecessary complexities in the industry.

Here's a podcast episode description with a fresh title. Title: The Cache That Cried Apocalypse: Lotem Karmon on the Ad Tech Crisis That Was Just a Subsidy Ending Description: Microsoft sent an email, picked a date, said the word "deprecate," and an entire industry started shopping for a funeral. Pre-bid cache was dying on April 30th, and large publishers were staring down caching bills of fifty to a hundred thousand dollars a month for a thing most of them didn't know they were using. Then Lotem Karmon, VP of Operations at Primis, did the one thing nobody in ad tech is paid to do. He looked. He logged his own system and found the creative was already sitting in browser memory the entire time. The cache was an elevator to a basement to fetch a toy that was already in the room. Primis turned it off and gained one percent in revenue, because the pointless round trip had been quietly leaking money for years. On this episode of The ADOTAT Show, Pesach Lattin and Lotem use a dead cache as a crime scene to investigate the thing the industry is engineered never to ask out loud: how much of ad tech is necessary, and how much is just complexity wearing a lab coat so you'll feel too dumb…
