The role of first-party data in machine learning

Machine learning models require high-quality data to produce accurate outcomes, with the principle of 'garbage in, garbage out' being critical. In mobile advertising, first-party data—collected directly from users through their app interactions—has become essential as third-party data sources decline due to privacy regulations like GDPR and CCPA, and platform changes such as Apple's AppTrackingTransparency and Google's Privacy Sandbox. Relying on third-party data poses legal and reputational risks, as seen with fines against Sephora and Instagram.

Moloco's approach emphasizes using first-party data in a privacy-safe manner, leveraging deep neural networks to train models before campaign launch. This reduces training time and costs, enabling quicker return on investment. By translating raw first-party data into artificial languages, Moloco scales limited data into sizable training sets without relying on IDFA or other identifiers.

This method allows for personalized, real-time bidding that adapts to new regulations and user preferences, providing a competitive edge over traditional DSPs that rely on third-party signals and longer training periods.
