Glean is the stronger choice when the deciding factor is analytics & tracking workflow fit, while Fathom Analytics has the clearer case when pricing shape, deployment control, or rollout risk matters more. For product and marketing teams, the practical decision is not feature count; it is which product better supports understanding user behavior, measuring campaign performance, and making data-driven decisions without forcing a costly migration six months later.

Event tracking and data model
Winner: Glean. For event tracking and data model, Glean is the safer default because its profile fits the way product and marketing teams evaluate this decision: workflow fit, rollout cost, ownership model, and time to value. Glean is positioned as enterprise ai search and knowledge discovery platform, while Fathom Analytics is positioned as privacy-first, simple analytics; that difference matters when the comparison moves from a feature checklist into daily operation. If your team is using this category for understanding user behavior, measuring campaign performance, and making data-driven decisions, test the winner against one production workflow and one admin task before committing. Fathom Analytics can still win when its ecosystem, contracts, or migration path reduces change management, but it requires a more deliberate rollout plan.
