Case Study: Warmies achieves 44.6% faster homepage TTFB and 3% higher revenue per visitor with Nostra

Warmies boosts revenue per visitor 3% with Nostra

Warmies, a company that creates comforting self-care products, was reviewing its software spend and wanted to validate the ROI of Nostra. After initially seeing speed gains from Nostra, they challenged whether they could achieve the same performance through their own in-house Shopify optimization work, which would allow them to simplify their tech stack.

To test this, Warmies paused Nostra for a 30-day sprint dedicated to Shopify theme and app improvements. After completing their internal work, they turned Nostra back on for an A/B test. Layering Nostra's edge-caching and optimization services on top of their newly improved stack resulted in a 44.6% faster homepage TTFB and a 3% increase in revenue per visitor, proving Nostra delivered significant incremental value.
