Northbeam does not work well for most small Shopify brands, and the reason is mathematical rather than a product quality issue. Northbeam's media mix modeling requires sufficient ad spend volume to generate statistically reliable attribution signals. Below roughly $50,000 to $100,000 per month in ad spend, the model has too few data points to outperform simpler attribution methods meaningfully, while the platform's cost and complexity remain the same as for brands spending ten times that amount. For small Shopify brands spending under $50,000 per month on paid acquisition, there are better-fit tools at every price point. This post tells you the exact threshold where Northbeam earns its investment, and what the right alternatives are below it.
