Haus

Haus is an AI-powered causal marketing measurement platform that helps brands quantify the true incremental impact of their advertising investments. The platform replaces traditional multi-touch attribution — which overcounts conversions — with statistically rigorous geo-split experiments: treatment regions see ads while holdout regions do not, enabling causal measurement of actual revenue lift. Haus offers four core products: Incrementality Experiments for on-demand causal testing, Causal MMM (media mix modeling) for cross-channel budget allocation, Causal Attribution for daily incrementality reporting, and Haus Copilot for AI-assisted experiment design and optimization. The company runs more than 4,000 experiments per year, has optimized over $30 billion in annual ad spend, and serves brands whose combined revenue exceeds $1 trillion, including FanDuel, Intuit, Wayfair, Coursera, Dyson, Sonos, and Invisalign. Haus was founded in 2021 by Zach Epstein, drawing on expertise from leaders previously at Google, Amazon, Netflix, Spotify, and Meta. The company is headquartered in San Francisco and has raised $37 million, including a $17M Series A led by Insight Partners in 2023 and $20M in additional financing from 01 Advisors in 2024.
