Case Study: Nécessaire boosts paid media revenue and unified ROAS with Fospha

Nécessaire boosts paid media revenue 61% with Fospha

Nécessaire, a premium personal care brand, faced the challenge of measuring marketing performance across its entire omnichannel ecosystem, which included its DTC site and marketplaces like Amazon. Ad platform reporting and multi-touch attribution were blind to these cross-channel halo effects, making it impossible to quantify the true impact of channels like TikTok. The brand needed a comprehensive measurement solution, which it found with Fospha and its Halo service.

Fospha implemented its Unified ROAS metric, which captures performance across all channels, turning measurement into a strategic operating system for Nécessaire. This solution provided a unified view that broke down siloed thinking and informed weekly optimizations and major strategic decisions. The results were significant, including a +61% YoY growth in paid media revenue, a +25% uplift in TikTok Unified ROAS, and a +58% uplift in Amazon Sponsored Products Unified ROAS during BFCM 2025, validating Fospha's data-driven approach.
