Haus

Incrementality testing and causal measurement for DTC ad spend

Official site →

Haus runs geo-holdout experiments to measure which ad campaigns actually drive incremental sales vs. conversions that would have happened anyway. Brands use the results to cut wasted spend and confidently scale what works. It fits best for brands spending meaningfully across two or more paid channels who suspect their platform-reported ROAS is overstated.

What Haus does for Shopify brands

  • Geo holdout tests reveal non-incremental ad spend -> budget reallocated to channels with proven lift
  • Causal MMM replaces platform-reported attribution -> confident spend decisions across Meta, Google, TikTok
  • Automated test design and reporting -> analyst hours freed from manual measurement work
