haus

haus (operating at haus.io) is an AI-powered causal marketing platform engineered for data-driven decision-making in enterprise advertising. Founded in 2021 by CEO Zach Epstein and headquartered in the United States, haus solves the long-standing challenge of proving marketing spend’s true business impact. Traditional attribution models often misallocate budgets by relying on correlation rather than causation, leading to wasted ad spend and missed growth opportunities. Under the hood, haus combines state-of-the-art causal inference, econometrics, and proprietary AI to analyze marketing data with statistical rigor, isolating the incremental impact of campaigns. This empowers global brands to optimize billions in ad spend with precision, reducing guesswork and maximizing ROI. Backed by $55.3M in funding from Insight Partners and 01 Advisors, haus has positioned itself as a trusted partner for Fortune 500 companies and high-growth enterprises seeking measurable marketing outcomes.
