Read-only access to the accounts you already have.
Authorize Meta, Google Ads and TikTok with OAuth; Amazon and retail media follow. No pixel to install, no tag to change, no customer data to upload.
How it works
From platform claims to a number you can defend.
No clean room, no identity graph, no new pixel. Catalxst takes what the platforms already report, puts it on common terms, and shows its work.

Self-reported ROAS can run well ahead of reality: analysts put true incremental return on one widely publicized $12 retail-media ROAS at 30–60% of the claim. Benchmarks cited are vendor-reported (Haus, Jul 2025; Measured, Jun 2026).
