Gareth Glaser, CEO and founder of Gamera, joins Corey and Joe fresh off announcing his fundraise. Gareth—former chair of Prebid.js and founder of RTK—explains Gamera's mission: creating a shared inventory identifier so buyers actually know what placements their ads run on. They discuss why the sell side has been "the Wild West," how the MFA crackdown proved transparency works, and why his "Gareth Hates Ad Tech" blog built trust before he hired salespeople. The goal? Make the open web work as efficiently as walled gardens—without taking sides.
