Measured via live holdout on production traffic, twelve months into the partnership. Not a launch-day spike, a sustained, compounding result.
Nostra commits to a minimum 3% CVR lift. Performance-based pricing means if they don't clear it, they don't get paid. The floor isn't a goal — it's a promise.
Trust-sensitive category, heavy mobile traffic, paid acquisition, first-time visitors, heavier tech stacks — brands that fit this profile consistently land well above the median.
Every number comes from a live production A/B test — a statistically significant holdout group served the unaccelerated experience, measured against the rest. No attribution models, no synthetic benchmarks.
300+ enterprise and high-growth brands rely on Nostra to deliver instant site speed, stronger SEO performance, deeper personalization, and clean, actionable marketing data.
