Holdout Labs provider review
An overview of Holdout Labs' event-marketing measurement service and its read-only advertising-platform connections.
Effective September 4, 2026
What Holdout Labs does
Holdout Labs is an event-marketing measurement and decision-support service. It brings together advertising reporting, ticketing context, creative information, and event milestones so a team can review supporting evidence before deciding what to do next.
Connected advertising data
With a client's authorization, a workspace administrator may connect a Google Ads or Meta Ads account to Holdout Labs for reporting and analytics that support event-marketing measurement and decision review.
The current connector is read-only. It does not create, edit, publish, delete, or manage advertising campaigns, ad sets, ads, budgets, or audiences in Google Ads or Meta Ads.
Manual decisions
Holdout Labs does not automatically change an advertising account. Budget, targeting, creative, and campaign changes remain actions for the customer's team to make in the applicable advertising platform after manual review.
