Palantir is expanding its commercial business by pitching its AI platform, AIP, to advertising agencies for use in inventory planning, programmatic sales, and campaign optimization. Despite its controversial work with intelligence agencies, Palantir has secured clients like United Airlines, Tyson Foods, and more recently, Lowe's and General Mills for AIP. The company aims to differentiate itself in the ad industry, amidst growing interest in AI, while facing potential reputational risks due to its government work.
