Case Study: David Protein achieves unified omnichannel measurement and profitable growth with WorkMagic

The Measurement Methodology Uniting Finance and Growth at David Protein

David Protein, a fast-growing functional food brand, faced significant measurement challenges during its rapid expansion from direct-to-consumer sales into Amazon and retail channels. Their existing tools created conflicts between platform-reported data and internal analysis, eroding trust and preventing confident financial forecasting. The brand needed a unified way to measure the true impact of its advertising, especially the hidden "halo effect" on sales outside its own website.

WorkMagic provided a solution through its incrementality testing framework, which offered a single source of truth for the impact of advertising across all sales channels. This aligned David Protein's finance, growth, and operations teams on one reliable dataset. The results were significant: WorkMagic revealed that 18% of total sales were driven by Meta ads, uncovered a 36% overestimation in DTC orders, and recommended a 40% increase in ad spend to maximize sales while maintaining return on ad spend. This gave the company the confidence to scale its advertising budget profitably.
