How Gaia stacks up

Gaia is built for measurable hiring results, not just job visibility. Its AI is trained on 1 billion hiring data points, enabling intelligent targeting to reach people actively and passively looking for work, wherever they are online.

Unlike aggregator-only models, Gaia runs programmatic, cross-channel campaigns across Google Display, Google Search, Facebook, Instagram, TikTok, Reddit, LinkedIn, YouTube, X, Pinterest and Snapchat.

‍

Key differentiators:

• AI-powered targeting with predictive modelling.

• Cookie-free retargeting to re-engage high-intent visitors.
